Karyological Studies on Some Indian Charophyta
(1992) B.V.S. Subrahmanyam; Y.B.K. Chowdary
Cytological investigations on two taxa of Chara Linn. (C. vulgaris var. gymnophylla f. grovesii and C. zeylanica var. sejuncta f. formosa) and a taxon of Nitella Ag. Leonh. (N. heterodactyla) were carried out. Nuclear events conformed to the standard pattern of mitosis described. The chromosome numbers determined are n=35 for C. vulgaris var. gymnophylla f. grovesii, n=42 for C. zeylanica var. sejuncta f. Formosa and n=18 for N. heterodactyla. All the three taxa were investigated for the first time and are new reports. © 1992, Japan Mendel Society, International Society of Cytology. All rights reserved.
Karyology of Nitella from South India
(1992) B.V.S. Subrahmanyam; Y.B.K. Chowdary
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.
