Morphological characteristics of pollen Betula verrucosa Ehrh. (syn. B. pendula) depending on habitat

Abstract

As a result of carrying out by means of scanning electronic microscopy of the comparative analysis of morphological traits of two samples of pollen Betula verrucosa Ehrh. from different habitats, it is revealed reliable distinctions between length of a polar axis, equatorial diameter and the area of apoporial field. The length of the polar axis of the samples of dry pollen grains from Kiev defined from 16.49 to 22.26 µm and from the samples of dry pollen grains from Ivankov from 16.88 to 22.51 µm. The length of the equatorial diameter from 18.95 to 26.96 µm and from 20.95 to 28.08 µm accordingly.
