Abstract

Cytogenetic studies on four species of vascular coastal and water plants from Russian Far East are presented. During the present investigation the next chromosome numbers have been revealed: Gypsophila pacifica (2 n = 34), Allium sacculiferum (2 n = 32), Mertensia maritima (2 n = 24), and Nelumbo komarovii (2 n = 16). Unusual chromosome numbers for these species have not been noted but it was the first case of karyological studies of Nelumbo komarovii from the Jewish Autonomous Region and most northern habitat. The number of nucleoli in interphase nuclei of these species was counted. Interphase nuclei of studied species contain 1–4 nucleoli except in A. sacculiferum so far which have 1–2 nucleoli per cell. Different points of view on polyploidy of studied species are discussed. [ABSTRACT FROM AUTHOR]
