Abstract
Benzyladenine (BA) induced flowering when applied at a high concentration (10−3M) to the cotyledons of seedlings of Pharbitis nil held in a non-inductive photoperiod (continuous irradiation). The transition to flowering occurred rapidly (within 4 to 5 days) following as few as two days of application of BA. There was no flowering after 20 days in control seedlings. Induction of flowering by BA was sometimes, but not invariably, associated with (i) greater retention of dry matter in the cotyledons and (ii) inhibition of shoot elongation and (iii) a slower rate of increase in root and shoot dry weight. Slowing stem elongation by application of growth inhibitors or by removal of one or both cotyledons did not induce flowering. Various cytokinins other than BA were active but so was triacanthine a structurally-related, non-cytokinin compound. Non-hormonal action of these compounds is implied. Possible direct effects of BA on processes of flowering are discussed.
