Growth physics and water relations of red-light-induced germination in lettuce seeds : V. Promotion of elengation in the embryonic axes by gibberellins and phytochrome.

abstract：:In the qualitative short-day plant Impatiens balsamina, gibberellic acid (GA3) not only promoted the formation of floral buds in response to suboptimal photoinductive conditions and reduced the number of SD cycles that are required for their development into flowers, but also caused initiation of floral buds under non...
