A Comparative Karyological Study of Root and Embryo Tissue of a Few Genera of Leguminosae

Abstract

Detailed analysis of chromosomes was undertaken in Lathyrus sativus, Pisum sativum, Crotalaria juncea, Trigonella foenum-graecum, Dolichos lablab, Phaseolus mungo, P. vulgaris, and Glycine max of Leguminosae with the aid of improved methods in both root and embryonic cell. Data on mitosis in tissues of embryo is hitherto unrecorded. The present investigation has demonstrated that with the technique devised, tissues of the embryo can be successfully utilized for chromosome analysis in this family. However, for the comparative study of the chromosome complements choice of similar organ is essential.
