Cytological Studies on Luzula Chromosome. II Pachytene Chromosome of Luzula Purpurea

Abstract

The distal sequence of Luzula purpurea chromosomes at meiotic prophase has been studied. The result obtained indicates that as shown in Figs. 2-11 a well differentiated structure which may imply the centromere structure has been confirmed on both distal parts of every chromosomes; this will support the third hypothesis refered to in the introduction. At the same time the presence of chiasmta in the bivalent chromosomes has also been suggested in contrast to the current opinion.
