摘　　要：研究外源激素对鸡冠刺桐花期的影响,选用赤霉素、丁酰肼、2,4-D这3种激素的3个浓度(1×10-4、3×10-4、8×10-4 g·mL-1),分别在6月中旬花芽发育初期、7月中旬开花前期和8月中旬开花期3个时间段对刺桐的花芽进行处理,观察花期的长短。试验结果表明:赤霉素、丁酰肼、2,4-D均能延长刺桐的花期,3×10-4g·mL-1的赤霉素效果最好。This paper aims to examine the effect of exogenous hormones on flowering erythrina with three levels of concentrations （1 × 10^-4 ,3 × 10^-4 ,8 × 10^-4 g.mL^-1 ） of gibberellins,damin- ozide and 2,4 -D as the hormones.In the three sessions respectively as the early budding devel- opment period of mid-June,the early flowering period of mid-July and the flowering period of mid-August, we tended the buds of erythrina and observed the flowering lengths.The results show that gibberellins, daminozide and 2,4 - D can all extend the lengths of the flowering period of erythrina, but gibberellins on the concentration of 3× 10^-4 g. mL^-1 perform best.
