Аннотация: The genetic diversity and population structure of Siberian fir (Abies sibirica LEDEB.) in Middle Siberia were studied on the basis of allozyme variation analysis at 20 loci. The vegetatives buds collected from 260 trees in nine populations representing different geographical localities and altitudinal sites were used as materials for study. Horizsontal starch gel electrophoresis was applied to analyze the isozyme patterns of 11 enzyme systems. 20% of the gene loci assayed were revealed to be polymorphic at 95%, and 35% at a 99% criterion. The mean number of alleles per locus, the mean observed heterozygosity, the mean expected heterozygosity, and the effective number of alleles were equal. The obtained data indicates a low level of genetic diversity and a weak differentiation among the A. sibirica populations studied in Middle Siberia. The most significant difference in structure was that between Kozulka and Western Sayan.

Seasonal development of phloem in Siberian larch stems
[Text] / G. F. Antonova, V. V. Stasova // Russ. J. Dev. Biol. - 2008. - Vol. 39, Is. 4. - P207-218, DOI 10.1134/S1062360408040024. - Cited References: 82

Аннотация: The seasonal development of phloem in the stems of Siberian larch (Larix sibirica Ldb.) was studied over two seasons on 50-60-year-old trees growing in a natural stand in the Siberian forest-steppe zone. Trees at the age of 20-25 years were used to study metabolites in differentiating and mature phloem elements, cambial zone, and radially growing xylem cells in the periods of early and late wood formation. The development of the current-year phloem in the stems of 50-60-year-old trees started, depending on climatic conditions, in the second-third decades of May, 10-20 days before the xylem formation, and ended together with the shoot growth cessation in late July. Monitoring of the seasonal activity of cambium producing phloem sieve cells and the duration of their differentiation compared to the xylem derivatives in the cambium demonstrated that the top production of phloem and xylem cells could coincide or not coincide during the season, while their differentiation activity was always in antiphase. Sieve cells in the early phloem are separated from those in the late phloem by a layer of tannin-containing cells, which are formed in the period when late xylem formation starts. The starch content in the structural elements of phloem depends on the state of annual xylem layer development. The content of low molecular weight carbohydrates, amino acids, organic acids, and phenols in phloem cells, cambial zone, and xylem derivatives of the cambium depends on the cell type and developmental stage as well as on the type of forming wood (early or late) differing by the cell wall parameters and, hence, by the requirement for assimilates. Significant differences in the dynamics of substances per dry weight and cell were observed during cell development.

Аннотация: Environmental conditions causing stress have a significant effect on the generative organs of Scotch pine. The parameters characterizing pine pollen are subject to significant interannual variations and are closely connected with weather and climatic conditions in the period of pollen formation. Airborne pollutants affect the quality of pine pollen, which is especially apparent in the years favorable for the formation of microspores. The ability of Scotch pine pollen to germinate and form pollen tubes in the regions with different technogenic loads proved to be significantly lower than in tree stands of the background areas.

Аннотация: The impact of long-term seasonal soil freezing, drought, and waterlogging on the rhizosphere of young Scots pine trees (Pinus sylvestris L., age class 1) has been simulated in experiments. The results have shown that cold stress exposure leads to reduction of the rates of linear and radial tree growth and of chlorophyll content in needles, a shift in the peak of starch content, and initiation of free amino acid deposition in the aboveground plant parts. Drought activates utilization of carbohydrate reserves and amino acid accumulation in the root bast, whereas soil waterlogging stimulates deposition of carbohydrates but causes a decrease in the levels of chlorophyll and amino acids in all plant tissues.

VARIATION AMONG AND WITHIN MOUNTAIN BIRCH TREES IN FOLIAGE PHENOLS, CARBOHYDRATES, AND AMINO-ACIDS, AND IN GROWTH OF EPIRRITA-AUTUMNATA LARVAE

Аннотация: Leaf quality of the mountain birch (Betula pubescens ssp. tortuosa) for herbivores was studied at several hierarchical levels: among trees, among ramets within trees, among branches within ramets, and among short shoots within branches. The experimental units at each level were chosen randomly. The indices of leaf quality were the growth rate of the larvae of a geometrid, Epirrita autumnata, and certain biochemical traits of the leaves (total phenolics and individual phenolic compounds, total carbohydrates and individual sugars, free and protein-bound amino acids). We also discuss relationships between larval growth rate and biochemical foliage traits. Larval growth rates during two successive years correlated positively at the level of tree, the ramet, and the branch, indicating that the relationships in leaf quality remained constant between seasons both among and within trees. The distribution of variation at different hierarchical levels depended on the trait in question. In the case of larval growth rate, ramets and short shoots accounted for most of the explained variation. In the case of biochemical compounds, trees accounted for most of the variance in the content of total phenolics and individual low-molecular-weight phenolics. In the content of carbohydrates (total carbohydrates, starch, fructose, glucose, and sucrose) and amino acids, variation among branches was generally larger than variation among trees. Variation among ramets was low for most compounds. No single leaf trait played a paramount role in larval growth. Secondary compounds, represented by phenolic compounds, or primary metabolites, particularly sugars, may both be important in determining the suitability of birch leaves for larvae. If phenols are causally more important, genet-specific analyses of foliage chemistry are needed. If sugars are of primary importance, within-genet sampling and analysis of foliage chemistry are necessary.

Seasonal development of phloem in scots pine stems

Аннотация: The formation of phloem was studied for two years in stems of 50 to 60 year old trees of Scots pine (Pinus sylvestris L.) growing in nature. The development of phloem of the current year begins 10 to 20 days before the xylem formation and is completed with the termination of shoot growth in the end of June. Observations over the seasonal activity of cambium producing sieve cells of phloem and duration of their differentiation as compared to the xylem derivatives of cambium have shown that the maxima of formation of phloem and xylem cells could coincide or not coincide by season, while the activities of their differentiation were always in antiphase. The sieve cells of early phloem were separated from those of late phloem by a layer of tannin-containing cells, which are formed simultaneously with the formation of late xylem cells by the cambium. Seasonal dynamics of accumulation of starch grain in structural elements of the phloem is related to the xylem development. The content of metabolites in differentiating and mature phloem elements, in the cambium zone, and in the xylem cells growing in the radial direction depended on cell specificity, stage of their development, and type of forming wood, early or late, which differ in the cell wall parameters and, hence, requirement of assimilates. Significant differences were described between the content of low molecular weigh carbohydrates, amino acids, organic acids, and phenol compounds using two methods of calculation: per dry weight and per cell.

Аннотация: The effect of spring defoliation on different aspects of growth and metabolism of 10-year Scots pine trees (Pinus silvestris L.) in natural stands of the Krasnoyarsk forest-steppe region have been studied. These aspects include the structure of annual xylem and phloem increments, the content of starch and photosynthetic pigments in phloem, and the activity of antioxidative enzymes in xylem and phloem. It is shown that defoliation reduces shoot elongation, as well as the length and mass of needles and width of annual rings in xylem and phloem. It also stimulates late wood formation, an increase in total contents of photosynthetic pigments in the needles of newly formed shoots, and a reduction of starch contents in stem phloem. A significant increase of peroxidase activity in the xylem of defoliated trees can be a sign of oxidative stress. Defoliation has an evident negative effect on the formation of the annual rings of xylem, but does not have that strong an impact on phloem genesis. In general, during defoliation, the reserve function of the trees prevails over the growth function.

Аннотация: Biotrophic fungus Melampsorella caryophyllacearum (Pucciniastraceae, Pucciniomycetes, Basidiomycota) developing in tissues of a fir (Abies sibirica) causes broom rust. Physiological mechanisms of plant resistance and fungus pathogenicity are not clear. The purpose of this work was an assessment of a role of secondary compounds and carbohydrates in mechanisms of interaction of Siberian fir and fungus M. caryophyllacearum. The 20-year age trees of Siberian fir grow in a mountain taiga zone in suburban forests of Krasnoyarsk (Central Siberia). Two options (one-year axes and needles of the current year without signs of damage by the fungus, and infected ones) were compared. Samples were taken on 3 trees 3 times during vegetation season: on June 21 (a phenology stage of shoot growth and a formation of pathogen etion), on July 19 (a phenology stage of summer vegetation and the period of active sporulation) and on September 10 (a phenology stage of autumn coloration of leaves and dying off the infected needles). The lignin and resin content were determined by weight method (the lignin determined with thioglycolic acid, the resins - by dissolving in pentane), carbohydrates - by the method of copper reduction using glucose as a standard, PAs - by coloring of solution after adding n-butanol / HCl mixture and heating. Starch was determined by coloring with iodine. The analysis of ANOVA proved reliable influence of various factors (phenology stage, plant organ (needles, axis), presence/absence of fungus infestation) on the content of PAs, lignin, monosaccharides (p < 0.05). The content of resin depended on plant organ only (resin content was more in axes, than in needles; p < 0.05). The tendency to starch accumulation in the infected axes during vegetation appeared to be caused by breakage of carbohydrates outflow. Infecting by the fungus caused decrease in the content of monosaccharides (p<0.05) that probably was connected with active consumption of mobile carbohydrates by the biotroph. The accumulation of PAs was revealed in needles and axes induced by M. caryophyllacearum fungus. Unlike PAs, the lignin concentration differently changed in the infected plant tissues. The accumulation of lignin was noted in diseased needles. In the infected axes in July the lignin content was significantly lower in comparison with control (p < 0.05). The found effect appeared to be manifestation of successful inhibition of plant protection by fungus. We suggested a hypothesis of the delayed lignification according to which a fungus inhibits synthesis of lignin and increases the chances in overcoming of protective barriers of a host. Perhaps, the pathogen influences carbon distribution by reducing its part for synthesis of lignin and increasing thereby synthesis of carbohydrates which further actively uses. The obtained data is agreed with concept according to which with effector molecules, biotrophs manipulate the defense machinery of the host in order to delay defense responses to gain enough time to multiply and spread into neighboring cells. © 2017 Russian Academy of Sciences.

The obtained data is agreed with concept according to which with effector molecules, biotrophs manipulate the defense machinery of the host in order to delay defense responses to gain enough time to multiply and spread into neighboring cells. © 2017 Russian Academy of Sciences.

Перевод заглавия: Influence of Chronical Partial Defoliation of Larch by Casebeareron Stem Physiological Parameters
Аннотация: В очаге лиственничной чехликовой моли Coleophora sibiricella Falkovitsh в чистом лиственничнике исследован защитный ответ флоэмы ствола лиственницы сибирской Larix sibirica Ledeb. на поранение или инокуляцию ствола грибным индуктором. В качестве грибного инокулята использовали мицелий офиостомового гриба Ceratocystis laricicola Redfern & Minter, его экстракт и белковую фракцию, полученную из экстракта. Содержание лигнина, крахмала, конденсированных дубильных веществ (проантоцианидинов) во флоэме определено в начале опыта (0 сут), через 7 и 14 сут. С помощью анализа ANOVA показано, что параметры ответа флоэмы не зависели от формы грибного инокулята (р ≥ 0.918), но зависели от других факторов (р ≤ 0.005) – повреждения кроны молью, времени от начала опыта, наличия инокулята в ране
In the long-term explosion of mass reproduction of larch casebearer Coleophora sibiricella Falkovitsh in pure larch stand the stem phloem responses of larch trees (Larix sibirica Ledeb.) to wounding damage or inoculation of the trunk with the fungal inductor. Mycelium of the ophiostomoid fungus Ceratocystis laricicola Redfern & Minter, its extractive and protein fraction obtained from the extractive were used as a fungal inductor. The content of lignin, starch, condensed tannins (proanthocyanidins) in the phloem was determined at the beginning of the experiment (0 days), after 7 and 14 days. Using ANOVA analysis, it was shown that the response parameters of the phloem did not depend on the shape of the fungal inoculum (p ≥ 0.918), but depended on other factors (p ≤ 0.005) - damage to the crown by the moth, time from the start of the experiment, and the presence of the inoculum in the wound

Аннотация: Береза повислая (Betula pendula Roth.) характеризуется как устойчивый к техногенному загрязнению среды вид древесных растений. Известно, что генеративные процессы растений и, в частности, формирование и жизнеспособность пыльцы крайне чувствительны к воздействию техногенного загрязнения. Исследования жизнеспособности пыльцы проводились в условиях Средней Сибири, в наиболее распространенной группе типов леса - березняках разнотравных, произрастающих в пригородной зоне крупного промышленного центра г. Красноярска, на восьми пробных площадях. Несмотря на устойчивость вида, мужские генеративные органы B. pendula оказались чувствительными к воздействию промышленного загрязнения. Исследования показали снижение качества пыльцы при усилении степени техногенной нагрузки, достоверных различий по диаметру пыльцевых зерен в различных условиях произрастания, как и деформированных пыльцевых зерен не обнаружено. Уровень изменчивости размеров пыльцевых зерен по диаметру в биоценозе не превышал 9,3-9,9 %. Максимальное число проросших пыльцевых зерен отмечалось в фоновых условиях, минимальное - на восточной окраине города, по основному направлению переноса техногенных аэрозолей. Длина пыльцевых трубок у деревьев, растущих в этих условиях, уменьшалась более чем в 2 раза по отношению к критическому значению (диаметр пыльцевого зерна 18-20 мкм). Выявлены взаимосвязи прорастания пыльцы и количества пыли, аккумулированной на листовых пластинках, а также содержания в ассимиляционной массе свинца и алюминия ( r = - 0,1-0,3; р ≤ 0,05). Функциональные показатели пыльцы березы повислой можно рекомендовать в качестве биоиндикационного показателя при проведении мониторинга окружающей среды.
Betula pendula Roth. is tolerant to tehchnogenic air pollutants. However, the viability of pollen decreases under stress conditions, as well as under air pollution. The researches were conducted in Middle Siberia on eight plots of motley birches near industrial city of Krasnoyarsk. In each plot on west side of 15-20 trees, male twigs were cut at pollination time. Pollen was extracted from the male generative organs for size and viability (potential, by starch test, and realized, by in vitro germination) determination. The results were analyzed by statistical methods. The researches have revealed reduction of pollen viability under technogenic pollution and reliable differences in pollen grain diameters under different growing conditions, whereas deformed pollen grain were not revealed. The variability of pollen grains in diameter in the biocenosis did not exceed 9.3-9.9 %. Maximum number of sprouted pollen grains observed under background conditions, and minimum at the eastern border of city in the main direction of the transfer of technogenic aerosols. The length of pollen tubes in trees growing under these conditions decreased by more than twice in comparison to the critical value (namely, pollen grain diameter of 18-20 µm). Regression analysis has shown correlations between pollen germination and accumulation of dust on foliage, as well as of lead and aluminum content in the foliage ( r = - 0.1-0.3, р ≥ 0.05)). In spite of tolerance of the species to air pollution, Betula pendula male generative structures are sensitive to the contamination. Pollen viability can be used as a bioindicator of environmental pollution at monitoring.

В условиях повышения уровня техногенной нагрузки на границе с городом снижаются прорастание пыльцы, длина пыльцевых трубок, накопление основного питательного вещества - крахмала.
The Siberian spruce (Picea obovata Ledeb.) pollen viability was studied on the border of Krasnoyarsk city as well as unpolluted growth conditions. The study discovered the variability and correlation between the functional characteristics of pollens, as well as a low rate of development anomalies. The viability of pollen growth in forest ecosystems of the Eastern Sayans middle mountains (northeast border of national park “Krasnoyarskie Stolby”) decreased under pollution press. A great variety of pollen viability characteristics of the Siberian spruce pollen makes evident the high degree of flexibility and adaptability of species′ reproductive processes.
