Аннотация: Karyotypes of three Larix species (L. sibirica, L. gmelinii, and L. cajanderi) were analyzed using fluorescence in situ hybridization (FISH) with 45S and 5S ribosomal RNA gene probes and 4',6-diamidino-2-phenylindole (DAPI) staining. Two major 45S ribosomal DNA (rDNA) loci (per haploid genome) have been observed in the intercalary regions of two metacentric chromosomes, III and IV, of L. sibirica; in addition to them, minor nucleolus organizing regions (NORs) were mapped in pericentromeric regions of chromosomes I, II, VI, and XII. Two closely related species, L. gmelinii and L. cajanderi, showed similar hybridization patterns; both species possessed an additional major locus of 45S rDNA in the distal region of the long arm of submetacentric chromosome VII that is absent in L. sibirica. Only one locus of the 5S rDNA was found in all larch species we studied; it was located in the distal region of the chromosome III short arm, which also carried the major NOR in the opposite arm. This chromosome containing major loci of the two ribosomal RNA gene families can serve as a marker of the genus Larix. The intra- and interspecific karyotype diversity in the genus Larix is discussed.

Аннотация: High-resolution scanning with Synchrotron Radiation X-ray Fluorescence Analysis (SRXFA) was applied to investigate element distributions in tree rings. Two cores of Siberia Larch have been investigated with resolution 100-200 mkm. Two groups of elements in tree rings with different trends have been found. The members of the first group are Br, Zn, Cl, whose trends correlate with each other. Moreover, trends of Br, Zn, Cl in tree rings are similar to the trend of atmosphere precipitation in the region investigated. Other group of elements are represented by K, Ca, Sr, Mn, Fe, but their trends differ sufficiently from trend of elements of the first group. Extended fixation of elements in tree rings is observed for elements of the first group over the whole interval investigated (150 years). In contrast, elements of the second group mainly accumulate in external part of tree stem. (c) 2007 Elsevier B.V. All rights reserved.

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.

Аннотация: In the long-term (30 years) field provenance experiment (Novosibirsk, Russia) with Scotch pine Pinus sylvestris L. from different geographical populations, X-ray fluorescence analysis with synchrotron radiation (XRFSRA) was used to estimate the concentration of 16 chemical elements in different components of the phytomass collected from living trees and the soil under them. The statistically significant influence of the "geographical population" factor on the elemental composition of different components of phytomass and soil was shown. A relationship between chemical properties and morphometric traits was found.

Аннотация: Regeneration patterns of Pinus sylvestris L. juveniles in central Siberian glades were studied in relation to cold-induced photoinhibition. Spatial distribution of seedlings in different height classes revealed higher seedling densities beneath the canopy than beyond the canopy, and significantly higher densities of seedlings < 50 cm tall on the north side of the trees. These patterns coincided with differences in light conditions. Compared with plants on the north side of canopy trees (north-exposed), photosynthetic photon flux (PPF) received by plants on the south side of canopy trees (south-exposed) was always higher, making south-exposed plants more susceptible to photoinhibition, especially on cool mornings. Chlorophyll fluorescence data revealed lower photochemical efficiency and increased non-photochemical quenching of small (20-50 cm in height), south-exposed seedlings from spring to early autumn, indicating increased excitation pressure on photosynthesis. Maximum rate of oxygen evolution was less in south-exposed plants than in north-exposed plants. Increased pools of xanthophyll cycle pigments and formation of the photoprotective zeaxanthin provided further evidence for the higher susceptibility to photoinhibition of south-exposed seedlings. A linear mixed model analysis explained many of the physiological differences observed in seedlings according to height class and aspect with early morning temperature and PPF as predictors. The link between photoinhibition and differential distribution of seedlings by height class suggests that photoinhibition, together with other environmental stresses, decreases the survival of small, south-exposed P sylvestris seedlings, thereby significantly affecting the regeneration pattern of central Siberian pine glades.

Аннотация: During winter and early spring, evergreen boreal conifers are severely stressed because light energy cannot be used when photosynthesis is pre-empted by low ambient temperatures. To study photosynthetic performance dynamics in a severe boreal climate, seasonal changes in photosynthetic pigments, chloroplast proteins and photochemical efficiency were studied in a Scots pine forest near Zotino, Central Siberia. In winter, downregulation of photosynthesis involved loss of chlorophylls, a twofold increase in xanthophyll cycle pigments and sustained high levels of the light stress-induced zeaxanthin pigment. The highest levels of xanthophylls and zeaxanthin did not occur during the coldest winter period, but rather in April when light was increasing, indicating an increased capacity for thermal dissipation of excitation energy at that time. Concomitantly, in early spring the D1 protein of the photosystem II (PSII) reaction centre and the light-harvesting complex of PSII dropped to their lowest annual levels. In April and May, recovery of PSII activity, chloroplast protein synthesis and rearrangements of pigments were observed as air temperatures increased above 0degreesC. Nevertheless, severe intermittent low-temperature episodes during this period not only halted but actually reversed the physiological recovery. During these spring low-temperature episodes, protective processes involved a complementary function of the PsbS and early light-induced protein thylakoid proteins. Full recovery of photosynthesis did not occur until the end of May. Our results show that even after winter cold hardening, photosynthetic activity in evergreens responds opportunistically to environmental change throughout the cold season. Therefore, climate change effects potentially improve the sink capacity of boreal forests for atmospheric carbon. However, earlier photosynthesis in spring in response to warmer temperatures is strongly constrained by environmental variation, counteracting the positive effects of an early recovery process.

Аннотация: Induction kinetics of chlorophyll fluorescence (the Kautsky effect) and delayed fluorescence (DF) of some cold climate species were studied in both laboratory and in situ experiments to assess their vlaue as indicators of plant health. Experiments included studies of natural variability of fluorescence in connection with the seasonal leaf maturation process, as well as the influence of environmental stress factors, such as ozone. It was found that parameters of induction curves (normalized variable fluorescence, time of its half decrease) could be used as indicators of plant health. No significant differences have been elicited between the information content of the Kautsky effect and induction curves of DF as tools for remote sensing. It is suggested that measurements of the single decay curves of DF are preferable for remote estimation of photosynthetic capacity. В© 1994.

Аннотация: Differences in terms of depth of dormancy have been revealed in the provenace trial of Scots pine based on an analysis of parameters of the zero fluorescence level, as well as the content of chlorophylls and abscisic acid, which corresponds to the results of studying the pine-needle morphological traits and phenological observations. Trees of the southern climatype different in terms of needle morphological traits and the length of phenological stages are characterized by a deeper dormancy than those of the northern climatype. It is assumed that, due to climate change, northern climatypes would be more vulnerable during winter-spring thaws, which were not typical of these regions in former times. © 2014 Pleiades Publishing, Ltd.

Аннотация: Forest fire represents one of the most serious abiotic stress factors that influence the function and productivity of ecosystems globally. Siberian pine forests are often exposed to forest fires, but they are not always harmful to them. This paper discusses the possibility of using fluorescent methods to assess the thermal effects on the assimilation apparatus of Scots pine (Pinus sylvestris L.) needles. The assimilation apparatus of pine needles was reestablished after exposure to convective, simulating the effect of ground fire heat flow, though the recovery rate depends on the impact force. The analysis of fast and delayed fluorescence characteristics revealed differences in the thermostability of the Scots pine needles showing certain modification of physiological processes in plants under the influence of stress factors with a positive acclimation effect. The Scots pine needles grown after ground fire are more resistant to the recurrent sublethal temperature, and this effect is maintained during the next growing season. This paper suggests that reforestation planning, particularly burning (low-intensity fire), will result in improved tree physiology that will lead to an increase in Scotch pine survival rate due to repeated heat stresses. Furthermore, the fluorescence method can be used to diagnose the thermic resilience of pine needle and assess high-temperature effects. © 2017 by the Committee on Forestry Sciences and Wood Technology of the Polish Academy of Sciences and the Forest Research Institute in S?kocin Stary.

Аннотация: We studied the effect of sublethal temperatures, far exceeding a photosynthetic optimum, on assimilatory apparatus of Scots pine (Pinus sylvestris L.) during recovery after surface fire. We tracked the quantitative composition of pigment complex, the heat resistance, and the rate of recovery of photosynthetic activity in pine forests growing in forest-steppe in similar climatic and soil conditions, and having various age of fire disturbance. The needles of the Scots pine differed in heat resistance, as shown by the chlorophyll fluorescence. The heat stress has configured physiological processes and formed positive acclimation. We show that longevity of recovery period controls reparation of photosynthetic apparatus. The heat stress of shoots during sleeper fire induces heat resistance of buds, which generate the heat resistant needles over the following growing season. © 2018, Izdatel'stvo Nauka.

Аннотация: During a forest fire, plants are affected by high temperatures causing stress. At the time of burning, it is difficult to record temperature changes in tree crowns and the associated effects on photosynthesis. This paper presents the results of modelling a high-temperature effect simulating a convective flow from a ground fire. Evaluation of the response was carried out by the parameters of rapid fluorescence (Fv/Fm, ETR), the state of the pigment complex, and the relative water content in the needles. To characterize the degree of heat endurance and short-term effects concerning thermal damage, saplings of Scots pine (Pinus sylvestris L.) were used at different times during the growing season (June, July, August, September). Experimental heating at 55 °C lasted for 5 and 10 min. There were different levels of heat resistance by the needles. Data in June show that heating of the saplings significantly suppressed photosynthesis. In July, August, and September, the photochemical quantum yield (Fv/Fm) was restored to 75% and 60% from the initial level after 5- and 10-min heating, respectively. The electron transport rate (ETR) for saplings in September was restored to their initial level within 3 days after a short heat exposure. Restoration of the photosynthetic activity in needles was observed after a 5-min impact, but by the end of the study period, restoration had not reached control values. A longer heating of 10 min resulted in an irreversible suppression of photosynthesis and destruction of the photosynthetic apparatus, as evidenced by the decrease in the number of photosynthetic pigments. © 2019, Northeast Forestry University.

Аннотация: The Central Siberian Plateau is undergoing rapid climate change that has resulted in increased frequency of forest fires and subsequent alteration of watershed carbon and nutrient dynamics. Across a watershed chronosequence (3 to 100 years since wildfire) we quantified the effects of fire on quantity and composition of dissolved organic matter (DOM), stream water nutrient concentrations, as well as in-stream nutrient uptake. Wildfires increased concentrations of nitrate for a decade, while decreasing concentrations of dissolved organic carbon and nitrogen (DOC and DON) and aliphatic DOM contribution for five decades. These post-wildfire changes in stream DOM result in lower uptake efficiency of in-stream nitrate in recently burned watersheds. Nitrate uptake (as uptake velocity) is strongly dependent on DOM composition (e.g. polyphenolics), ambient dissolved inorganic nitrogen (DIN), and DOC to DIN ratios. Our observations and experiments suggest that a decade-long pulse of inorganic nitrogen and a reduction of DOC export occur following wildfires in streams draining the Central Siberian Plateau. Increased fire frequency in the region is thus likely to both decrease DOM and increase nitrate delivery to the main stemYenisei River, and ultimately the Arctic Ocean, in the coming decades.

Аннотация: During a forest fire, plants are affected by high temperatures causing stress. At the time of burning, it is difficult to record temperature changes in tree crowns and the associated effects on photosynthesis. This paper presents the results of modelling a high-temperature effect simulating a convective flow from a ground fire. Evaluation of the response was carried out by the parameters of rapid fluorescence (Fv/Fm, ETR), the state of the pigment complex, and the relative water content in the needles. To characterize the degree of heat endurance and short-term effects concerning thermal damage, saplings of Scots pine (Pinus sylvestrisL.) were used at different times during the growing season (June, July, August, September). Experimental heating at 55 degrees C lasted for 5 and 10 min. There were different levels of heat resistance by the needles. Data in June show that heating of the saplings significantly suppressed photosynthesis. In July, August, and September, the photochemical quantum yield (Fv/Fm) was restored to 75% and 60% from the initial level after 5- and 10-min heating, respectively. The electron transport rate (ETR) for saplings in September was restored to their initial level within 3 days after a short heat exposure. Restoration of the photosynthetic activity in needles was observed after a 5-min impact, but by the end of the study period, restoration had not reached control values. A longer heating of 10 min resulted in an irreversible suppression of photosynthesis and destruction of the photosynthetic apparatus, as evidenced by the decrease in the number of photosynthetic pigments.

Аннотация: Distribution of chemical elements in tree rings bears important information on various biogeochemical processes. In order to achieve a reliable interpretation of the information, it is necessary to know the degree of variation in the content of chemical elements both at the level of the entire species and at the level of individual trees. The research aims to determine which chemical elements have a stable distribution in the trunks of a number of conifers: Siberian spruce (Picea obovata Ledeb.), Scots pine (Pinus sylvestris L.), Siberian larch (Larix sibirica Ledeb.), and Siberian pine (Pinus sibirica Du Tour). The data for the analysis were obtained on the basis of the long-term experiment in forest growing. The experimental site was laid out in 1971-1972 in the vicinity of Krasnoyarsk by the staff of the Sukachev Institute of Forest of the Siberian Branch of the Russian Academy of Sciences. Before planting the seedlings, the soil ground was mechanically levelled, and thus, sufficiently equal growth conditions were created for all plantings. Cores with a diameter of 12 mm were sampled from three normally developing trees of each species and analyzed using modern X-ray fluorescence methods. Content relative values of elements (counts) were obtained with the Itrax Multiscanner (COX Analytical Systems). The content of elements in the tree rings was characterized by the concentration and reserve of elements. Concentration was calculated as the number of counts per 1 mm(2) of the ring area; reserve was calculated as the number of counts over the entire ring area. Each of these variables was defined by the parameters of linear slope in the calendar year series and the standard deviation. The cluster analysis was performed in the 4-dimensional space of the obtained parameters. This allowed determining whether the series of element distributions from different trees and species are grouped. Three elements (Ca, Co, and P) show high stability of distribution parameters in tree rings with no regard to tree species. A number of other elements (Mn, Pb, Cl, Cr, Ni, Sr, and W) are stably grouped depending on the species. The results of the research enable to focus on the study of the elements stably distributed in the conifer trunks.
