Variability of morphological features of the Siberian larch introduced on the disturbed land of the Egorievsk deposit of phosphorite

The purpose of this work is to study the variability of the morphological features of Siberian larch introduced on land, disturbed by open phosphorite mining (in the city of Voskresensk, Moscow Region). Endogenous and individual variability of morphological features of seeds (the length and width of a seed), cones (the length and width of cones, the number of scales in the cone) and needles (the length of needles) are analyzed, the relationship between these attributes in relation to their orientation, tightness and shape, the degree of genetic determination of the investigated features is determined on the basis of the heritability factor in the broad sense (H2). A comparative analysis of the individual variability of Siberian larch growing on the Egorevsk phosphorite mining with a population from natural growth conditions (Irkutsk Forestry, Irkutsk Region) and Ivanteevsky Dendrological Garden (Ivanteevka, Moscow Region) was carried out. All the studied introduced plants are native of Irkutsk.
