Abstract

Karyotypic analysis of Chara corallina Linn., C. vulgaris Linn., C. gymnopitys Linn. and Nitella translucens Ag. collected from natural habitats revealed that C. corallina has n=42, C. vulgaris and Chara gymnopitys have n=14 while Nitella translucens has n=18 chromosomes. All the species had differences in individual chromosome length, total chromatin length, total frequency between the complements of their chromosomes. The proposed standard karyotype formula were 6Lm + 2Mm +26Msm + 6S1m + 2S2m for Chara corallina, 4Mm + 8S1m + 2S2m for Chara vulgaris, 6Mm + 4S1m + 2S2sm +2S2m for Chara gymnopitys and 6Lm + 2Lsm + 6Mm+ 2Msm + 2S1m for Nitella translucens.

Key words: Chara; Nitella; Karyotype; Green algae; Bangladesh
