title: Comparative characteristics of karyometric parameters of microsporocytes and tapetum cells of the formed anthers of long-styled and short-styled plants Jasminum fruticans L. (Oleaceae)
abstract: In connection with the study of the functional activity of generative structures in heterostylous plants, a comparative karyometric analysis of tapetum cells, as well as microsporocytes of the formed anthers of long-styled and short-styled plants Jasminum fruticans L. (Oleaceae) was carried out. Based on the measurement of the nucleus areas, nucleolus, counting the number of nuclei and nucleoli in cells, the total values of the areas of nuclear structures were calculated. Since the processes of
