Description
Summary:Evaluated the variability of the content of essential oil in wood Siberian fir greenery in 9 age groups. It is shown, that except for the regrowth of forest regeneration measures its content to any perestojnym is reduced by half. Content in essential oil bornilacetata that determines the quality and price of the product, is reduced from 34 to 24%. When you change the latitude growing Siberian fir (from Krasnoyarsk forest-steppe at taiga Lesosibirsk) its contents in wood greenery increases. Found a significant change in the content of essential oil in ohvoennyh shoots to the height of the tree crown. Its content at the top of the Crown in 1,5 times higher than the lower part. Offered dependency change in the content of essential oil in ohvoennyh shoots to the height of the tree crown. Received adequate model of age-related changes of the content of essential oil in ohvoennyh shoots, to assess the contribution and the nature of decreasing of essential oil in the assimiljacionnom apparatus of the Siberian fir in the age interval from 0 to 200 years. Held parametric identification model for Siberian fir growing in Krasnoyarsk forest and the Lesosibirsk region. The maximum content of essential oil from the Siberian fir corresponds from 25 to 30 years and then declining to a minimum at overaged trees. Оценена изменчивость содержания эфирного масла в древесной зелени пихты сибирской в девяти возрастных группах. Показано, что за исключением подроста его количество от молодняков к перестойным древостоям снижается вдвое. Содержание в эфирном масле борнилацетата, который определяет качество и стоимость продукта, уменьшается с 34 до 24 %. При изменении широты произрастания пихты сибирской (от Красноярской лесостепи к Лесосибирской тайге) его содержание в древесной зелени возрастает. Установлено существенное изменение содержания эфирного масла в охвоенных побегах по высоте кроны дерева. Его количество в верхней части кроны в 1,5 раза выше по сравнению с нижней частью. Предложена зависимость для оценки содержания эфирного ...
