Abstract
The analysis of generative organs of Larix sibirica and Larix gmelinii growing in natural and artificial plantings of Siberia is presented in this work. The collection of cones of Gmelin larch growing in the natural plantings in the northern (Evenkiysky Field station) and in the eastern (Bodaybo) range boundaries. In artificial plantings, samples of cones of L. sibirica and L. gmelinii were taken in the arboretum of Sukachev Institute of Forest SB RAS (Krasnoyarsk). Based on information about the length and width of cones and the number of seed scales, the seed productivity of the generative organs of larches was calculated. The study of the structure of the L. gmelinii crop on the northern (Evenkiysky Field station) and the eastern border of the area (Bodaybo) showed that cones of this species are formed smaller than trees from the arboretum (16.07±0.4 mm versus 19.53±0.3 mm). The seed productivity of the female cone of L. sibirica is higher than that of L. gmelinii. It was found that with a sufficiently high seed productivity of female cones in larch species, the formation of full-grain seeds in L. sibirica and L. gmelinii is extremely low. Most of the seeds are damaged by conobionts. In order to preserve the larch gene pool, it is necessary to use modern reproduction biotechnologies. One of these technologies is the biotechnology of somatic embryogenesis in in vitro culture.
