Abstract: | Application of gibberellic acid (GA3) before and sucrose after the inductive dark period promotes flowering in Xanthium. The promotive effects of these two compounds are independent but additive. Sucrose application either before or utter the dark period has promotive effect on the flowering response. These effects are additive. The roles of pre- and post-induction high-intensity light period and of GA3 in the promotion of flowering have been discussed. It has been suggested that sucrose application promotes flowering by increasing translocation of the flowering stimulus and by promoting the rate of development of the terminal male inflorescence. It has also been suggested that GA3-induced promotion of flowering is due to the increased synthesis as well as translocation of the flowering hormone. |
