Cytomorphological studies of three species of Paspalum Linn. from South India.

摘要: Cytological studies have been made on three species of Paspalum, two which were collected from natural populations while P. scrobiculatum is a cultivated species. commersonii consists forms with diverse morphological varieties, occurring either as mesophyte or hydrophyte. and orbiculare show regular meiosis n=20 2n=40. In contrast, in has somatic number 2n=60 very irregular total asynapsis chromosomes. This probably hybrid origin apomictic. The results the present cytological clearly indicate that variations characters habit shown by these are correlated distinctness. Therefore taxa deserve separate specific rank suggested Bor (1960).
