Variability of vegetative and generative organs of introduced Korean Dahurian larch.

Abstract

The article analyzes the variability of vegetative and generative organs of Korean Dahurian larch (Larix olgensis) growing in the conditions of introduction, on the example of conditions of the Tsytsin Main Moscow Botanical Garden. Morphological characters of seeds (length and width of seeds), cones (length of cones, width of cones, number of scales in cones) and needles (length of needles) were analyzed. The relation between these characters is estimated based on the calculation of the correlation coefficient (r) and the correlation ratio (η). The statistical indicators analysis of the quantitative characteristics of Korean Dahurian larch and Dahurian larch confirms the conclusion that these larches belong to different species.
