Аннотация: Thanks to acclimation, trees overcome environmental changes and endure for centuries. The anatomy of water conducting cells is an important factor determining plant success. Forming cells are coupled with the environment and their properties are naturally archived in the wood. Its variability across tree rings can thus provide a retrospective of plant's hydraulic adjustments. In this work, we measured lumen and wall thickness of tracheids along tree-rings to explore how trees regulate their conducting system under variable plant-water conditions. Tracheids were measured along 51 dated rings of five mature Larix decidua and Picea abies trees from a low elevation site. Anatomical-based chronologies of annual growth performance, hydraulic conductance and safety, and construction costs were built. Similarities among chronologies and the relation to monthly climate data were analyzed. Most parameters displayed high annual plasticity which was partly coherent among trees and mostly associated with radial growth. In general, summer drought reduced growth and potential hydraulic conductivity of the forming ring, and increased hydraulic safety and construction costs. To evaluate the functional relevance of the annual acclimation, the conductivity of the forming ring relative to the entire sapwood needs to be assessed.

Аннотация: The effect of stand density on the antioxidant system of Scots Pine (Pinus silvestris L.) and Siberian Pine (Pinus sibirica Du Tour) was studied. The dynamics of concentrations of chlorophyll, hydrogen peroxide, glutathione, ascorbic acid, and dehydroascorbic acid were investigated during the vegetation period. In addition, the activities of superoxide dismutase, catalase, peroxidase, glutathione reductase, and ascorbate peroxidase were observed in the 1-year needles of 26-year-old trees with an initial stand density of 0.5 and 128 thousand individuals ha(-1).

Аннотация: We compared effects of ambient (360 vpm) and elevated (720 vpm) carbon dioxide concentration ([CO(2)]) and high and low nutrient supply rates on stem growth, annual ring structure and tracheid anatomy of Siberian larch (Larix sibirica Ledeb.) seedlings over two growing seasons. Elevated [CO(2)] had no significant effect on either stem height or diameter growth; however, both stem height and diameter growth were enhanced by the high nutrient supply rate, and these increases were stimulated by elevated [CO(2)]. Elevated [CO(2)] tended to increase the width of the annual xylem ring, the number of cells in a radial file spanning the ring, and tracheid lumen diameter, whereas it tended to reduce cell wall thickness, although there were no statistically significant CO(2) effects on tracheid anatomy. Changes in tracheid cell morphology seemed to be dependent on changes in shoot elongation rates.

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: 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: The response of vegetation to climate change is of special interest in regions where rapid warming is coupled with moisture deficit. This raises the question of the limits in plants' acclimation ability and the consequent shifts of the vegetation cover. Radial growth dynamics and climatic response were studied in Scots pine (Pinus sylvestris L.), Siberian larch (Larix sibirica Ledeb.), and silver birch (Betula pendula Roth.) in the forest-steppe, and for Siberian elm (Ulmus pumila L.) in the steppe of South Siberia, as indicators of vegetation state and dynamics. Climate-growth relationships were analyzed by the following two approaches: (1) correlations between tree-ring width chronologies and short-term moving climatic series, and (2) optimization of the parameters of the Vaganov-Shashkin tree growth simulation model to assess the ecophysiological characteristics of species. Regional warming was accompanied by a slower increase of the average moisture deficit, but not in the severity of droughts. In the forest-steppe, the trees demonstrated stable growth and responded to the May-July climate. In the steppe, elm was limited by moisture deficit in May-beginning of June, during the peak water deficit. The forest-steppe stands were apparently acclimated successfully to the current climatic trends. It seems that elm was able to counter the water deficit, likely through its capacity to regulate transpiration by the stomatal morphology and xylem structure, using most of the stem as a water reservoir; earlier onset; and high growth rate, and these physiological traits may provide advantages to this species, leading to its expansion in steppes. © 2019 by the authors.

Аннотация: In moisture-limited regions in which droughts leave a significant “footprint”, monitoring of quantitative climatic parameters and of forest adaptation and acclimation to these parameters is of utmost importance due to the ambiguity of spatial patterns in reaction of tree growth to drought and the variety of drought resistance strategies exhibited by trees at the genetic, morphological and physiological levels. This is a case study of the radial growth of Siberian larch (Larix sibirica Ledeb.) along the forest-steppe transect in the foothills of the Bateni Ridge (Kuznetsk Alatau, Southern Siberia, Russia) and of its climatic response and stability under the influence of droughts and contributing factors. In this region, a permanent mild moisture deficit is gradually increasing due to warming of the vegetative season by 0.14–0.19 °C per decade; droughts occurred in 1951, 1963–65, 1974–76, and 1999. The forests in the region are represented by pure larch stands in the west and mixed stands of larch with Scots pine and silver birch in the eastern portion of the ridge. The forest-steppe ecotone comprises a significant part of the ridge area, mainly on the southern and southeastern slopes. At 5 sampling sites, dependence of larch growth on precipitation (P) and standardized precipitation-evapotranspiration index (SPEI) during April–July of the current year and June–September of the previous year and on maximum temperature (Tmax) during May–July of the current year and July–September of the previous year was observed. We propose the use of a linear regression model based on the SPEI of these seasons as an individualized indicator of climate aridity, which is biologically significant for larch in the study area. An analysis of pointer years showed that precipitation in November (formation of snow cover) also contributes to larch growth. The larch in the study area tolerates moisture deficit, rebounding after the end of stress exposure. The spatiotemporal patterns of the stability indices revealed that despite the decrease in growth resistance and resilience with drought severity, these characteristics are higher at more arid sites due to trees’ acclimation to permanent climate aridity. The findings contribute to a better understanding of the capability of larch to further acclimatize and provide a basis for planning measures for conservation and/or restoration of the region's forests under climate warming; however, to clarify the contributions of factors at the individual and local scales, further investigation of the stability of larch growth at the level of individual trees may be required. © 2019 Elsevier B.V.
