Abstract
Internode elongation was induced during the seedling stage by foliar application of gibberellic acid (GA3, 1-1, 000 ppm) in floating rice and non-floating rice. The induction effect of GA3 was stronger in floating rice than in non-floating rice. Comparing Bangladesh floating rice with Thai floating rice, the induction effect was generally stronger in the former than in the latter. In each of both floating rices, it was stronger in the varieties which have good elongation ability than in those with inferior elongation ability. But, the promotion of elongation of both leaf sheath and leaf blade by GA3 did not differ among Bangladesh floating rice, Thai floating and non-floating rices.
