Abstract

In the previous reports (34, 35) it is reported that identical processes which induce flower formation in the short-day plant induce in the cucumber plant, at the first step, staminate flower differentiation. Increasing amount of the specific substance brought about by increasing amount of foliage leaves, affects the meristematic tissues, changing their activity from production of vegetative tissues to inception of floral primordia, and it may be that the flower forming substance at lower concentration induces staminate flower differentiation and with the rise of the concentration, bisexual and further pistillate flower differentiation. The specific substance, produced in the young mature leaves, is impelled to transfer by the bud or the young leaves.
