Bychkov S. Introduction potential of Pinus pallasiana D. Don and Pinus sylvestris L. in technogenously polluted territories of the Azov Sea coast

Object - Pinus pallasiana D. Don and P. sylvestris L. Intention: determination of introduction potential of these species in conditions of technogenously polluted regions territories of the Azov Sea coast. The comparative analysis of individual and population (group) variability of morphometric, reproductive indices and hereditary biochemical indices in in native populations and man-made plantations. The methods of isoenzymic analysis (Goncharenko et al., 1989). The methods of sexual reproduction investigation (Romanovsky, 1989; Nekrasova, 1986). The influence of steelworks emissions on life conditions, sexual process and the level of genetic variation of these species has been investigated. It is determined, that in the man-made plantations the basic level of genetic variation of native populations renews. The relation of allozymous variations with variability of morphologic indices of P.pallasiana has been studied. Practical proposals on these species use for making plantations at the Azov Sea coast have been developed.
