Abstract
A new cytological procedure specifically suited to maize endosperms is presented. It uses 8-hydroxyquinoline with sucrose and aeration to pretreat the tissues. Glusulase is used to spread the cells. the procedure makes it possible to squash endosperms into a single cell layer and to photograph as many as 70 chromosomes in the same focal plane. It also allows identification of translocation chromsomes. with a slight modification the technique has been applied successfully to root tips and other tissues.
