Researches of individual variation of female strobiles and needle morphometric indices of thirty Pinus allasiana
D. Don and Pinus nigra Arnold var. austriaca Hoss trees of 40-aged stands of the Donetsk Botanical Gardens
Dendrarium have been made. Valid differences concearning the morphometric indices being peculiar to length of
needles only. To determine genetic differentiation and these taxa similarity introduction stands of P. nigra var.
austriaca and natural population of P. allasiana from the Crimea were compared. Isozymes of 9 enzymous
systems were used as genetic markers. Their variability was analysed with the help of electrophoretic division in
7,5% polyacrylamide gel. Nei’s genetic distance between P. allasiana and P. nigra var. austriaca was not sensible
– 0.009. It was fixed on the base of 21 allozyme loci frequencies. Such low values of this universal index do not
give any reason for P. allasiana to be regarded to independent species category
