Karyotype analysis in three species of Rhizoclonium Kuetz.

摘要: Cytological studies of R. dimorphum, stagnale and crispum have been made for the first time. A count 24 chromosomes as diploid number has ascertained all three species their karyotypes also worked out. The degree relationship between calculated through Karl Pearson's coefficient correlation method. Recognition distinct supported in view appreciable difference with respect to total chromatin length, variations among chromosome complements TF%. possible means speciation genus Rhizoclonium suggested by shift position centromere alteration length chromosomes, since it is a homothallic alga such translocation well inversion homozygotes are expected be established easily.Meiotic 12 bivalents at diakinesis filaments preceding zoospore formation dimorphum. zoospores observed was quadriflagellate which new report genus.Diplobiontic life cycle dimorphum on basis that meiosis precedes formation.
