“…Еще в конце XIX века Р. Гартигом с учениками проводились исследования связи качества древесины и её технических свойств с анатомическим строением у хвойных пород, и был сделан вывод о том, что строение трахеид полностью объясняет колебания объемного веса (плотности) древесины хвойных пород [1]. Немецкими учеными лесоводами было отмечено, что все лесохозяйственные мероприятия, которые повышают долю поздней древесины, приводят к росту её плотности [2,8,16,18]. О влиянии разреживающих рубок проведено достаточно много исследований, однако они часто противоположны по своим выводам о влиянии рубок на процесс формирования плотности древесины.…”

“…Базисная плотность древесины измерялась методом максимальной влажности по проф. О. И. Полубояринову [8]. По предложенным в работах [3,4,8] конверсионным уравнениям определялась плотность древесины для всего ствола и далее, как средневзвешенная, для всего древостоя на пробных площадях.…”

Для определения соотношения зон поздней и ранней ксилемы, а также величины годичных приростов, полученные керны древесины шлифовались и сканировались.…”

“…Most larch forests in the world, considering both distribution area and wood stock, are in Eurasia (Schmidt 1995). Larch is fast-growing tree species producing high quality timber (Chubinski et al 1990) suitable for outdoor construction, due to its high mechanical strength and decay resistance (Polubojarinov et al 2000). In Finland, larch is considered equivalent to Scots pine with respect to decay resistance (Venäläinen et al 2001).…”

Vitality and height growth of two Larix species and provenances in a field trial located in north-west RussiaFedorkov A. (2014). Vitality and height growth of two Larix species and provenances in a field trial located in north-west Russia. Silva Fennica vol. 48 no. 1 article id 1053. 7 p. Highlights• Differences in tree vitality among provenances were insignificant (p > 0.05) at an early age.• The provenance effect was significant (p < 0.05) for total height.• These findings were in agreement with those of Lukkarinen et al. (2010) using the same material at the same age for field trial located in Punkaharju (Finland). AbstractVitality and height of Larix species and provenances originating from Russia were estimated in a 5-yr field trial performed in the Komi Republic (north-west Russia) using a fully randomized single-tree plot design with 7-8 blocks. Tree provenance had no significant (p > 0.05) effect on tree vitality, though for Larix sukazcewii originating from the European part of Russia, trees from the northern regions were more vital than those from southern regions. Provenance was a significant (p < 0.05) factor for height, where the average height of 136 cm varied considerably (168 cm for trees from Nizhnij Novgorod and 111 cm for trees from Ufa). There were no significant correlations when vitality and height were compared to geographic and climatic variables for the locations.

“…Modern research shows that the larch wood in natural and artificial plantations has very good physical-mechanical properties (Vihrov 1949;Polubojarinov et al 2000;Koizumi et al 2003;Karlman et al 2005;Topaloğlu, Ay 2010;Luostarinen 2011).…”

Neverov N.A., Belyaev V.V., Chistova Z.B., Kutinov Y.G., Staritsyn V.V., Polyakova E.V., Mineev A.L. (2017): Effects of geo-ecological conditions on larch wood variations in the North European part of Russia (Arkhangelsk region). J. For. Sci., The present study examines the macrostructure and density of larch wood and possible influences on the productivity of larch stands. The studies were conducted in the middle and sub-tundra taiga in the Arkhangelsk region. The selected trees were of the same age and diameter at breast height. In all sample plots the average annual ring width varied from 0.68 to 0.93 mm, the average content of latewood was about 29.7-35.1% and the average wood density of these old Siberian larch trees was 572 (500-698) kg·m -3 . There were no significant differences between sample plots in terms of the latewood content, density and annual ring width of the growth rings. Wood macrostructure of larch wood has the same values in forests growing in the sub-tundra and middle taiga. A possible explanation for this is the location of these stands in the karst landscape, which possesses abundant mineral nutrition. Geological factors are surpassing the influence of climatic factors and contribute to the formation of productive larch stands in the subtundra taiga in the European part of Russia.
