Research Articles


The present investigation has been focussed on mitotic and meiotic chromosome study of androdioecious Stichoneuron membranaceum from the state of Tripura. The somatic chromosome number in both the sexual phenotypes was found to be 2n = 18 having one pair of chromosomes bearing secondary constriction. Meiosis is regular and the presence of nine bivalents in pollen mother cells of male and hermaphrodite flowers suggest that the basic chromosome number is X = 9. The accentuated chromosome homology in androecious and hermaphrodite plants of S. membranaceum is the intrinsic character of their karyotypes.
