Karyology of Nitella from South India

Abstract

Karyological investigations on four taxa of Nitella have been carried out. The chromosome counts recorded are all new records to the respective taxa. Chromosome numbers are n=9, 27, 12 and 9 to Na furcata subspa flagellifera f. flagellifera RDW, Na furcata subsp. megacarpa f. megacarpa (T. F. A.) RDW, N. pseudoflabellata var. elegans (Pal) RDW and N. gracilis f. intermedia (Nordst.) RDW, respectively. N. graeilis f. intermedia is karyologically investigated from India for the first time. © 1992, Japan Mendel Society, International Society of Cytology. All rights reserved.
