THE ANALYSIS OF THE INTRAPOPULATION VARIATION OF THE ALMOND-LEAVED AND GRAY-LEAVED WILLOWS, TO BE CONDITIONED BY THE INFLUENCE OF THE GENETICO-ECOLOGICAL FACTORS

Abstract

The object of investigation: the natural populations of the almond-leaved and gray-leaved willows on the territory of the Desninsky Polesje. The purpose of the work: to establish the main laws of the intrapopulation variation of the almond-leaved and gray-leaved willows. The new type of the meiosis of the plants has been described, the high level of the aneuploidy in the populations has been established; the correlative-combination quazicontinuous character of the variation of the vegetative organs and the length of the pollen grains has been revealed. The method of revealation of the aneuploidy has been developed with the aid of the palinometric analysis; the dependence of the pollen grains dimensions on the conditions of inhabitation has been established.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
