Individual and geographical variability of 15-year-old seed offspring of grafted trees of siberian cedar pine
Abstract
The indicators of the seed offspring of the second generation of 15-year-old Siberian cedar pine, growing in the Karaulny forestry of the Educational and Experimental Forestry of SibSU (in the suburban zone of Krasnoyarsk), are given. Planting material is grown from seeds collected on a grafting plantation from mother trees of different geographical origin. Trees are planted on the plantation “LET-2” according to the scheme of 4×4 m. It was found that the plants have an average height of 1.1–1.4 m according to the experimental options, the length of the needles is 9.2– 10.0 cm. The maximum height is distinguished by the offspring of Tuvan origin, the length of the needles – by Tyumen and Yartsevo origin, the maximum amount of the current increase has trees of Altai origin. Three macrostrobyls were formed at this age on tree No. 14-40 of Chita origin. Specimens were selected in variants of different geographical origin according to the intensity of growth and the length of needles, which are recommended for vegetative reproduction to create plantations for the intended purpose.
