Аннотация: Experiments in intraspecific hybridization of Siberian stone pine, not just of this species but of different regional origins as well, have been carried out at a clone plantation in Middle Siberia (Krasnoyars forest-steppe). Crossings were realized using the principle of ecologo-geographical remoteness of populations. Siberian stone pine clones chosen for crossing had good growth and constant reproductive ability over many years. An analysis of the characteristics of hybrid female cones (weight, linear size, number of developed scales) and seeds (number, weight, seed fullness, viability) showed the positive influence of controlled pollination with combinations of different climatypes. The study of hybrid growing climatypes, resulting from crossing of the plain and mountain populations, also revealed signs of heterosis.

Аннотация: We studied the ecological conditions forming on the solifluction areas often occurring in cryolithic zone of Central Evenkia. A significant change of microenvironment was registered on some solifluction "microecosystems" that differ sharply form the control ones in plantation. The ecological conditions formed in these areas result in the change of species composition of vegetation and its diversity. However, we revealed no significant differences of separate ecological groups depending on hydrothermal and trophic conditions.

Аннотация: Phenomenological models of the forest plantations growth are analyzed. Those derived from the Verhulst's model are shown to fail describing qualitative effects reflecting tree growth, phytomass withdrawals, and plantation restoration. The method of phase portraits is used for exploration of the forest ecosystem dynamics, which allows to describe regulatory mechanisms of the growth processes, regulation delay, and feedback types. A bistable phenomenological model is suggested herewith to characterize dynamic processes in the forest ecosystems. Principal patterns of formation of the forest plantations at different stages of the forest generation processes are considered on the basis of that model, and ecological effects responsible for the plantation dynamics are revealed.

Аннотация: We present results of individual-based root system measurement and analysis applied for Larix gmelinii trees growing on the continuous permafrost region of central Siberia. The data of root excavation taken from the three stands were used for the analyses; young (26 years old), mature (105 years old), and uneven-aged over-mature stand (220 years old). In this article, we highlight two topics: (1) factors affecting spatio-temporal pattern of root system development, and (2) interactions between aboveground (i.e., crown) and belowground (i.e., root) competition. For the first topic, the detailed observation of lateral roots was applied to one sample tree of the overmature stand. The tree constructed a superficial (< 30 cm in depth) and rather asymmetric root system, and each lateral root expanded mainly into elevated mounds rather than depressed troughs. This indicated that spatial development of an individual root system was largely affected by microtopography (i.e., earth hummocks). For these lateral roots, elongation growth curves were reconstructed using annual-ring data, and annual growth rates and patterns were compared among them. The comparison suggested that temporal root system development is associated with differences in carbon allocation among the lateral roots. For the second topic, we examined relationships between individual crown projection area (CA) and horizontal rooting area (RA) for the sample trees of each stand. RA was almost equal to CA in the young stand, while RA was much larger (three or four times) than CA in the mature and overmature stands. Two measures of stand-level space occupation, crown area index (aboveground: CAI; sum of CAs per unit land area) and rooting area index (belowground: RAI; sum of RAs), were estimated in each stand. The estimates of RA1 (1.3-1.8 m(2) m(-2)) exceeded unity in all stands. In contrast, CAI exceeded unity (1.3 m(2) m(-2)) only in the young stand, and was much smaller (< 0.3 m(2) m(-2)) in the two older stands. These between-stand differences in RAI-CAI relationships suggest that intertree competition for both aboveground and belowground spaces occurred in the young stand, but only belowground competition still occurred in the two older stands. Based on this finding, we hypothesized that competition below the ground may become predominant as a stand ages in L. gmelinii forests. Methodological limitations of our analysis are also discussed, especially for the analysis using the two indices of space occupation (CAI, RAI).

Аннотация: The hygroscopic properties of the litter of coniferous (larch and pine) and deciduous (aspen and birch) stands were studied in terms of isotherms of water-vapor sorption and with use of thermal analysis methods (TG, DSC). It was found that most of the monolayer capacity belongs to subhorizons OL and OF of the larch and pine forest litters. The larch plantation litter has the highest hydrophilicity. DSC results show that the water is most strongly associated with the litter substance in subhorizon OL in coniferous plantations and OH in deciduous ones. The moisture supply in the litter of coniferous stands is greater than in deciduous ones.

Аннотация: Scots pine provenances from all over Russia planted in 1964 at the forest-steppe zone were analyzed. Eight tree-ring characteristics from 12 different provenances were measured densitometrically. The time span of tree-ring observation covers the period from 1969 to 1997. The sensitivity coefficient of latewood width, latewood and maximum densities and latewood percentage decreases in relation to the increasing latitude of the provenances. The growth of all studied provenances is dictated by the local weather and climate. The correlation coefficients of indices between the local provenance and the other provenances are not lower than 0.46-0.97, and the synchronicity coefficients are minimally 0.84. The Euclidean distances vary from 0.11 to 0.13 between the local provenance and the other provenances. All statistical parameters show that the interannual. variability reflects the prevailing influence of the local weather conditions. Variability of weather conditions determines up to 87% of the growth variability in the forest-steppe of southern Siberia.

Аннотация: Investigating the tolerance of plant reproductive systems to environmental changes has become a research priority under current climate change scenarios. Successful plant conservation requires knowledge of plant reproductive biology, particularly the meiotic characteristics of planted species. Meiosis, as part of microsporogenesis, is a critical plant developmental stage controlling future pollen quality. Meiosis in a Siberian fir (Abies sibirica) plantation, established in the Forest Arboretum of the Sukachev Institute, Russia, was studied from 2002 to 2004. The microsporogenesis pattern found for the Siberian fir appeared to be largely similar to that exhibited by other conifer species. Meiosis in the Siberian fir has the following characteristics: asynchrony, rapid progression of telophases I and II, and parallel and linear spindle arrangements at different meiosis II stages. General and specific meiosis irregularities were recorded at each stage. Some specific features of meiosis and the specific development of some irregularities were revealed. Pollen development analysis showed that irregular pollen grains made up less than 1% of all grains. The specific features of meiosis identified in fir trees growing in the Arboretum indicated low resistance of male reproductive structures to climatic changes and might account for high fir pollen sterility in this new environment.

Аннотация: Scots pine provenance trials were established in 1964 in forest-steppe and in 1974 in southern taiga zones of Central Siberia from seeds collected over whole Russia. Tree-ring characteristics (radial growth and density chronologies) from 12 and 16 provenances planted in those plantations were measured densitometrically. Tree-ring analysis revealed a retention of a genetically fixed response to climatic factors proper to pines' origin. Trees from higher latitudes keep the orientation towards accelerated growth at the beginning of a growing season, which is followed by a rapid transition to formation of latewood cells and deceleration of growth earlier, than in medium-latitude trees. Main climatic factors controlling tree-rings formation differed slightly between different provenances within plantations. Genetically fixed ability of the provenances are not great (less than 15%), that proves high adaptability of pines to abrupt climatic change. Tree-ring formation of Scots pine provenances is mainly determined by the environmental factors. В© Springer 2006.

Аннотация: The results of long-term work on the induction of somatic embryogenesis in Siberian pine (Pinus sibirica Du Tour) growing in a natural stand of trees and in clone grafting plantation located in the Western Sayan are shown. Controlled pollination of the clones of Siberian pine had a positive influence on the state of callus cultures. The cytological analysis of embryonal-suspensor mass made it possible to identify embryological structures morphologically close to zygotic embryos at early developmental stages; as a result, the callus tissue was recognized embryogenic. We revealed donor plants (clones), whose zygotic embryos in vitro can serve as a source of embryogenic callus tissue.

Аннотация: Afforestation in low-carbon-density areas has been proposed for mitigating climate change, because it leads to a reduction in the atmospheric carbon dioxide concentration. However, afforestation can be conducted for numerous purposes, and the complexity of tree species may render accurate estimation of the carbon (C) sequestration potential difficult. In this study, 22 cropland afforested plantations among 12 tree species and 4 study sites were investigated. We investigated stand development and aboveground biomass C accumulation of cropland afforestation in Taiwan, and examined how tree species and site conditions affected stand growth and yields. Results showed that average values of the mean diameter at breast height, tree height, stand density, and aboveground biomass C stocks for all studied plantation at 8-10 yr after planting were 12.1 cm, 8.5 m, 1272 trees ha-1, and 32.1 Mg C ha-1, respectively. The results also revealed that fast-growing tree species such as Swietenia macrophylla and Melia azedarach attained the highest growth rates and accumulated the most biomass C stocks, whereas slow-growing tree species such as Zelkova serrata exhibited the lowest growth rate and C accumulation potential. Trees grown at sites with deep soils outperformed those grown at sites with shallow and rocky soils. Overall, current cropland afforestation in Taiwan can enhance C sequestration, and also generate economic and ecological benefits. © 2016, Taiwan Forestry Research Institute. All rights reserved.

Аннотация: Morphogenesis and maturation of somatic embryos, ploidy, and genotyping of cell lines (CL) of embryogenic cultures of Larix sibirica Ledeb. in vitro were investigated during 2–6 years. It was revealed that from 2000 to 11103 globular somatic embryos were formed in proliferating CL. However, the ability of somatic embryos to the maturation and germination decreased. Cytogenetic study of embryonal-suspensor masses (ESM) of Larix sibirica demonstrated that cells of long-term cultivated cultures remained diploid. According to microsatellite analysis, proliferating CL of Siberian larch were characterized by weak allelic variability, and cell line 6 and cloned seedlings of this line were genetically stable and corresponded to the donor tree. Embryogenic cell lines composed the collection bank, which will be successfully used for plantation forest growing. © 2016, Pleiades Publishing, Ltd.

Аннотация: Оценена антимикробная активность летучих соединений хвои 23-летних клонов <i>Pinus sylvestris</i> L. методом «опарения» штриховых посевов микробных культур в чашках Петри. Исследования проведены 18 и 26 июля 2011 г. на трех тест-объектах - грамположительных бактериях <i>Staphylococcus epidermidis</i>, грамотрицательных бактериях <i>Esсherichia coli</i> и дрожжеподобных грибах <i>Candida albicans</i>. Оценка антимикробного действия сосны проводилась в сравнении с контролем по шкале фитонцидной активности в баллах от 0 (отсутствие эффекта) до 4 (сильный эффект). Средний балл фитонцидной активности клонов по отношению к отдельным тест-системам варьировал в пределах 0.00-3.00. Выявлены слабая дифференциация клонов сосны к <i>Staphylococcus epidermidis</i> и отсутствие достоверных межклоновых различий по воздействию эфирных масел сосны на остальные микробные тест-объекты. Частота парных сравнений, в которых обнаружены достоверные различия между клонами, составляет менее 5 % для S. epidermidis и около 1.5 % для всех тест-микробов. Наряду с этим прослеживались высокодостоверные эффекты времени проведения тестов (календарной даты), вида тест-объекта («патогена») и взаимодействия «дата тестирования - патогены» и «дата тестирования - клоны», на которые в 3-факторном дисперсионном анализе приходится около 23, 33 и 15 % соответственно. Наиболее вероятными причинами этого являются динамика состава летучих соединений хвои и взаимодействие генотип - среда, что должно стать объектом более пристальных исследований. Очень важным в этой связи является вопрос о сезоне, который оптимален для надежного выявления генотипов сосны, отличающихся максимальной фитонцидностью. Выявлена отрицательная межклоновая (генотипическая) корреляция между фитонцидностью сосны к <i>S. epidermidis</i> и к <i>C. albicans</i>. Возможно, это обусловлено обратно пропорциональной зависимостью между содержанием определенных компонентов в эфирных маслах, которые отвечают за ингибирование различных патогенных организмов. При анализе генетических особенностей протестированных клонов выделяются их совокупности, достоверно различающиеся, с одной стороны, по фитонцидности к стафилококку <i>S. epidermidis</i>, с другой - по индивидуальной гетерозиготности аллозимных локусов. Такого рода дифференциация генотипов отмечена впервые и также может быть в фокусе дальнейших исследований.
Streak inoculation of microbial test-cultures was treated with volatile emissions of needles of 23-years clones of <i>Pinus sylvestris</i> L. The study was conducted in July 2011 on three test-objects - gram-positive bacteria <i>Staphyllococcusepidermidis</i>, gram-negative bacteria <i>Esсherichia coli</i> and yeast-like fungi <i>Candida albicans</i>. Antimicrobial effect of pine volatile emissions was assessed in comparison with the control on 0 (absence of the effect) - 4 (strong effect) scale of antimicrobial activity. The mean marks of antimicrobial activity of clones, calculated in relation to separate test-systems, were within the limits of 0.00-3.00. The weak differentiation of pine clones to <i>S. epidermidis</i> is revealed. Frequency of pair comparisons in which statistically significant differences between clones was found to be less than 5 % for <i>S. epidermidis</i> and about 1.5 % for all the test-microbes. Alongside with it significant effects of the time of testing (calendar dates), a microbial species («pathogens») and interactions «date of testing-pathogens» and «date of testing-clones» were revealed: in ANOVA their effects amounted to nearly 23, 33 and 15 % of the total dispersion accordingly. The most probable reasons for it are dynamics of structure of essential oils and «genotype-environment» interaction that should become object of future research. In this connection, an important question is what is the season that is optimum for reliable revealing of the pine genotypes with maximal antimicrobial activity? Negative between-clones (between-genotypes) correlations between antimicrobial activity to <i>S. epidermidis</i> and to <i>C. albicans</i> are revealed. It is probably caused by inversely proportional dependence between concentrations of the components in essential oils, which are responsible for inhibition of various pathogenic organisms. The sample of investigated clones was divided into two sub-samples that sufficiently differed by the levels of both antimicrobial activity to <i>S. epidermidis</i> and individual heterozygosity of allozyme's loci. Such differentiation of genotypes is noted for the first time, and can be in focus of further studies.

Аннотация: Background: Soil respiration contributes to a large quantity of carbon emissions in the forest ecosystem. In this study, the soil respiration rates at three Taiwanese forest plantations (two lowland and one mid-elevation) were investigated. We aimed to determine how soil respiration varies between lowland and mid-elevation forest plantations and identify the relative importance of biotic and abiotic factors affecting soil respiration.& para;& para;Results: The results showed that the temporal patterns of soil respiration rates were mainly influenced by soil temperature and soil water content, and a combined soil temperature and soil water content model explained 54-80% of the variation. However, these two factors affected soil respiration differently. Soil temperature positively contributed to soil respiration, but a bidirectional relationship between soil respiration and soil water content was revealed. Higher soil moisture content resulted in higher soil respiration rates at the lowland plantations but led to adverse effects at the mid-elevation plantation. The annual soil respiration rates were estimated as 14.3-20.0 Mg C ha(-1) year(-1) at the lowland plantations and 7.0-12.2 Mg C ha(-1) year(-1) at the mid-elevation plantation. When assembled with the findings of previous studies, the annual soil respiration rates increased with the mean annual temperature and litterfall but decreased with elevation and the mean annual precipitation. A conceptual model of the biotic and abiotic factors affecting the spatial and temporal patterns of the soil respiration rate was developed. Three determinant factors were proposed: (i) elevation, (ii) stand characteristics, and (iii) soil temperature and soil moisture.& para;& para;Conclusion: The results indicated that changes in temperature and precipitation significantly affect soil respiration. Because of the high variability of soil respiration, more studies and data syntheses are required to accurately predict soil respiration in Taiwanese forests.

Аннотация: We present the results of cytogenetic analysis of seven young and long-term cultured embryogenic cell lines (CLs) of Larix sibirica obtained by somatic embryogenesis. All CLs were found to be mixoploid. Three CLs (1, 2 and 6 years of cultivation) were the most stable cytogenetically with 91-96% cells having diploid chromosome number 2n=24, typical for the species. These CLs can be successfully used for the development of planting material and in clonal plantation forestry. At the same time, some embryogenic CLs were shown to possess various chromosome and genome mutations. We found two aneuploidy proliferating CLs (2n=25 and 28) capable of somatic embryo formation. One of the CLs analyzed in a current study was found to be cytogenetically unstable with chromosome numbers ranging from 24 to 35 and containing one-two micronuclei in the interphase cells. Fluorescent in situ hybridization (FISH) and morphometric analyses of karyotypes of these embryogenic CLs allow an assumption that the trisomy for one or several chromosomes is the most widespread type of genomic disturbances in embryogenic CLs of L. sibirica.

Аннотация: In vitro cultivation of embryogenic cultures of Siberian larch on AI medium supplemented with different concentrations of antimicrobial peptides of two Trichoderma species, T.citrinoviride (strain TYVI 4/11) and T. viride (strain 346), has been performed to achieve a direct antimicrobial effect and initiate the mechanisms of induced resistance (regulatory function of embryogenic cultures) as well as to study the morphogenesis and growth activity of regenerant plants. The experiment was arranged using four cell lines, CL4, CL5, CL6, and CL12, differing in their embryogenic activity. The effect of treatment of cell cultures with Trichoderma peptides was manifested via significant growth stimulation of proliferating embryogenic cell lines, root growth stimulation, and formation of callus excrescences on regenerant plants. No difference between the treated and untreated variants was observed in seedlings. Conceivably, such peptide treatment may provide an increased immunity of soil-grown seedlings in forest nurseries. Study of the effect of biocontrol strains' use in a plantation reforestation to stimulate the growth and development of calluses and embryos and to obtain disease-resistant regenerant plants of conifer species will provide the development of a clonal silviculture, a new trend that recently appeared abroad (Park 2002, 2014).

Аннотация: Soil CO2 emission is one of the most important components of the global carbon cycle. This study analyzes the seasonal dynamics of soil emission for various land cover types in the middle taiga subzone of central Siberia during five growing seasons. It is shown that, throughout a vast area covered by pine forests and their derivatives formed on sandy soils, seasonal CO2 emission values are determined primarily by the moisture conditions and only secondarily by the temperature regime and ecosystem type. The effect of the forest type is manifested only under the most favorable moisture conditions. A new approach is proposed: divide the growing season into dry and moist periods depending on the threshold soil moisture for areas with different vegetation types.

Аннотация: Many environmental and climatic disturbances can significantly change the magnitude and pattern of litterfall. This study investigated the effects of typhoon disturbances on the seasonal and interannual patterns of litterfall on coniferous and broadleaf plantation stands in Xitou, central Taiwan. Throughout the study period from 2012 to 2018, typhoon disturbances were recorded in 4 of these 7 years, whereas only minor or even no typhoon disturbances occurred in the other 3 years. Our results demonstrated that the pattern of monthly litterfall varied substantially between the coniferous and broadleaf stands. The coniferous stands exhibited a substantial litterfall pulse due to typhoon disturbances. By contrast, typhoon disturbances exerted a minor impact on the broadleaf stands. The litterfall seasonality of the coniferous stands was higher than that of the broadleaf stands, especially in the years with typhoon disturbances. Furthermore, the yearly variation caused by typhoon disturbances was distinct at the coniferous stands; the annual litterfall mass at the coniferous stands in the years with typhoon disturbances was more than twice as high as that in the years without typhoon disturbances, namely 6,000 kg ha(-1) yr(-1) versus 2,500 kg ha(-1) yr(-1). By contrast, the annual litterfall mass at the broadleaf stands did not differ significantly among the study years. Because of high interannual variation, long-term sampling is essential for accurate estimation of annual litterfall at coniferous stands. For broadleaf plantations, interannual litterfall variation seems less critical, and spatial variability should be considered because of higher variability in terms of site conditions.

Аннотация: The visibility of the spatial distribution of soil moisture is achieved through mapping, which is most simply carried out according to a digital model. Information on soil moisture is stored in the attribute table field of the Geographic Information System (GIS) layer and available for editing and later use. It is shown that a digital moisture model can be obtained through the cross-spectrum analysis of soil moisture with terrain parameters (frame of mapping - a digital elevation model) and ranking of forest types in order of increasing soil moisture (frame of mapping - a feature layer of inventory plots). The mapping results are demonstrated in terms of 2 test sites in mountainous and flat areas. Soil moisture mapping based on the DEM (digital elevation model) data was performed for a test site located in the Axial Western Sayan district of the mountain taiga forests; where forest types, due to the spatial cross-spectrum analysis, are distributed by terrain parameters and ranked by soil moisture. The result of the spatial analysis of the DEM is a raster (digital elevation model of soil moisture). Soil moisture mapping based on the forest management materials is performed for the test area representing the southern taiga forests of the Angara region. Ranking of soil moisture is made on the basis of inventory plot descriptions of the test site. The data of inventory plots was excluded from the analysis. Growth of tree species is a priori impossible down there (wetlands, rivers and lakes). In a simplified form, a ranked range of soil moisture is also demonstrated relative to the forest type as a generalized qualitative indicator of forest site conditions. Regardless of the land category (plantation, burnt area or cutover), each inventory plot receives an additional quantitative indicator of soil moisture, followed by the possibility of determining the regression equations for the potential productivity of tree species. It is found that in the presence of a feature layer of forest management data, soil moisture mapping is preferable to be adapted from the forest management materials. It is shown that there is a dependence of the productivity of stands on soil moisture.

Аннотация: Investigating the tolerance of plant reproductive systems to environmental changes has become a research pri-ority under current climate change scenarios. The results of the investigations of meiosis at microsporogenesis in Siberian spruce (Picea obovata Ledeb.) under introduction are presented. The meiosis in the Siberian spruce plantation established in the Forest Arboretum of the Sukachev Institute, Russia, was studied in 2018. The microsporogenesis pattern found for the Siberian spruce appeared to be largely similar to that exhibited by other conifer species. The meiosis in the Siberian spruce has the following characteristics: identification of all stages of prophases I; asynchrony in different trees as well as in different meiocytes of the same tree and the same microsporangium; parallel and perpendicular as well as linear spindle arrangements at different meiosis II; irregularities of development at different stages. Some specific meiosis irregularities have never been revealed in natural populations of Central Siberia. The investigations of plant ontogenesis in new conditions of growth show the response of the plants on climate change. The specific features of meiosis identified in the spruce trees growing ex situ indicated high resistance of male reproductive structures to climatic changes. © 2020, Komarov Botanical Institute.
