Аннотация: Scots pine provenance trials established in Buryatia (western Trans-Baikal region) in Siberia were studied. The features of linear increment of 57 progeniers representing a significant part of the total Scots pine area in Russia are shown. Interpopulation variability in Scots pine progenies' linear increment index was found to increase in provenances during optimal moisture conditions during growing seasons. The correlation coefficients, between the linear incremewnt idexes and the climatype survival rate, showed a mostly positive link based on the contrast in conditions of the originating material populations.

Height increments and suevival of Pinus sylvestris climatypes in provenance trials in the western Trans- Baikal region
Impacts of climate change on the distribution of larix spp. and Pinus sylvestris and their climatypes in Siberia

Аннотация: Inter- and intraspecific effects of climate change were assessed for the dominant conifers of Siberia (60-140В°E and 48-75В°N): Larix spp. (L. sibirica, L. dahurica, and L. sukaczewii) and Pinus sylvestris . The approach employed a tri-variate (degree-days above 5В°C, degree-days below 0В°C, and a moisture index) estimate of the climatic envelope within which exists the actual ecological distribution of a species and their constituent climatypes (genotypes physiologically attuned to similar environments). Limits of the actual ecological distribution were approximated by reducing the climatic envelope according to effects of permafrost and interspecific competition. Climatypes were mapped within the climatic envelope according to the climatic interval that must separate populations for reasonable assurance of genetic differentiation. This interval was calculated from response functions that related 13-year growth and survival of a species to the difference in climate between the provenance of a climatype and the climate of numerous test sites distributed across Russia. Mapping species' distributions and their climatypes was done for the contemporary climate and for future climates predicted by the HadCM3GGa1 scenario of Hadley Centre. The results showed that if the forests of the future are to reflect the adaptedness of today, the distribution of species will shift and genotypes within species will be redistributed. Some contemporary climatypes are projected to disappear from Siberia while others common elsewhere would evolve. To mitigate these effects, climatypes should be transferred today to the expected future location of their climatic optima, a distance that is likely to approach 700-1200 km for these species.

climatype -- fluorescence -- provenance trial -- Scots pine (Pinus sylvestris L.) -- winter dormancy
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.

сосна обыкновенная -- географические культуры -- грибные патогены -- устойчивость -- летучие вещества -- хвоя
Аннотация: Исследован качественный и количественный состав летучих веществ в хвое у климатипов сосны обыкновенной в географических культурах в Красноярском крае, выделенных в разные группы по степени поражения в период эпифитотий, вызванных снежным шютте в 8-летнем и ценангиевым некрозом в 23–25-летнем возрасте. Выделенные группы условно названы “устойчивые” и “неустойчивые” к данным грибным патогенам. Исследование летучих соединений в хвое у климатипов сосны проводилось в 40-летнем возрасте. Выявлено, что группа “неустойчивых” климатипов, которые по своему географическому происхождению являются южными, в здоровом состоянии отличается от “устойчивых” северных достоверно бόльшими значениями относительных концентраций ряда летучих веществ, среди которых наибольшее содержание имеют Δ3-карен и камфен. Северные климатипы отличаются от южных более высоким содержанием вещества с наибольшей относительной концентрацией – α-пинена, а также других веществ: кариофиллена, лимонена и α-кубебена. По компонентному составу в газовой фазе выделяется самый северный климатип – печенгский, у 40% деревьев которого обнаружено редко встречаемое в эксперименте вещество – β-фарнезен. Исследование эфирного масла в хвое показало наименьшее количество веществ у “неустойчивого” сузунского климатипа, а наибольшее разнообразие выявлено у кандалакшского и долонского, представляющих разные группы устойчивости
Qualitative and quantitative composition of the volatile substances was performed in needles of different Scots pine climatypes in geographic cultures of Krasnoyarsk Krai, divided into several groups based on how much they were affected by epiphytoties of the snow blight at the age of 8 years and cenangium dieback at the age of 23–25. Based on that, the groups were named “resistant” and “nonresistant” to the aforementioned pathogenic fungi. Volatile substances analysis was carried out on 40-years old trees. It was discovered that the “nonresistant” climatypes that geographically come from the southern regions, while healthy differ from the “resistant” northern ones by having distinctively bigger relative concentrations of some volatile substances, mostly the Δ3-carene and camphene. Northern climatypes differ also by having higher relative concentrations of α-pinene, cariofillene, limonene and α-cubeben. Based on the component structure of the gase phase the northernmost climatype – pechengian – was distinguished, that possesses a substance rarely found during the experiment in 40% of specimens – β-farnesene. Volatile oil studies in pine needles have shown that the smallest number of substances can be found in “nonresistant” suzunian climatype, and the largest in kandalakshian and dolonian climatypes that belong to different resistance groups

Аннотация: Tree-ring width and latewood content were studied to assess the response of wood to growing conditions. Samples were taken from the trees of six Scots pine climatypes with contrast origin, grown in the conditions of provenance trials in southern taiga of Central Siberia (Boguchany forestry) and forest-steppe of Western Siberia (Suzun forestry). A comparative analysis of variance of mean values of the studied features between the climatypes within each test point and between the points is carried out. Correlation analysis was used to analyze the dynamics of the studied traits and as their response to weather conditions over a long period. It was revealed that in the forest-steppe conditions maximal radial increments for all climatypes were observed on average at the age of 9 and in southern taiga at the age of 12-16. Tree-ring width of the climatypes from the south is significantly lower in the forest-steppe conditions than that of of the representatives of northern origin. Climatypes transferred from a warmer climate to southern taiga are characterized by significantly larger values of tree-ring width than in the northernmost of the studied ones. The latewood content decreases in all studied climatypes of pine in southern taiga in comparison with forest-steppe. Significant response of the latewood content of climatypes in forest-steppe is observed not only with average monthly weather conditions of the second part of vegetation period but also with the first. It indicates a higher sensitivity of their wood structure to the complex of climatic and ecological conditions in the provenance trials of forest-steppe compared with southern taiga. The research results show that the Boguchany climatype is genetically stable in terms of the average values of tree-ring width and latewood content in forest-steppe and southern taiga.

Географические культуры -- сосна обыкновенная -- ширина годичного кольца -- доля поздней древесины
Аннотация: Изучена ширина годичного кольца и доля поздней древесины у деревьев шести контрастных по месту происхождения климатических экотопов (климатипов) сосны обыкновенной, выращиваемых в географических культурах в южной тайге Средней Сибири (Богучанское лесничество) и лесостепи Западной Сибири (Сузунское лесничество) для оценки реакции древесины на условия произрастания. Проведен сравнительный дисперсионный анализ средних значений исследуемых признаков между климатипами в пределах каждого пункта испытания и между пунктами. Исследована динамика элементов древесины и их реакция на погодные условия за многолетний период с помощью корреляционного анализа. Выявлено, что в условиях лесостепи у климатипов в среднем максимальные радиальные приросты отмечаются в возрасте9 лет, в южной тайге - позднее, в 12-16 лет. У климатипов с юга ареала в условиях лесостепи ширина годичного кольца имеет достоверно меньшие значения, чем у представителей северного происхождения. Для климатипов, перемещенных из более теплого климата в южную тайгу, характерны достоверно бóльшие значения ширины годичного кольца, чем у самого северного из исследуемых. Доля поздней древесины у всех изученных климатипов сосны в южной тайге уменьшается по сравнению с лесостепью.Значимая связь доли поздней древесины у климатипов в лесостепи отмечается не только со среднемесячными погодными условиями второй половины вегетационного периода, но и первой, что свидетельствует о более высокой чувствительности структуры ихдревесины к комплексу климатических и экологических условий географических культур по сравнению с южной тайгой. Результаты исследования показывают, что по средним значениям ширины годичного кольца и доле поздней древесины в лесостепи и южной тайге генетически стабильным является богучанский климатип.
