Abstract
THE presence of gibberellin-like substances in floral parts (petals plus ovary)1 and demonstrations that gibberellic acid (GA3) can promote the growth of sepals and petals1,2 have indicated that gibberellins are involved in the growth of flowers. Further evidence, presented here, indicates that in carnation the application of GA3 diverts assimilates to the flower and hastens development towards anthesis.
