.. kszl10.8%、12.9%、15.13%, and spraying paclobutrazol in 200 mg/L to the whole plants of the three species brought about 13.2、10.7、10.2 days of delay to the starting time of flowering. Their respective flowering duration was prolonged by 23.86%、17.62%、21.38%. Thus, spraying with GA3 in proper concentration made the three species flower earlier and have shorter flowering duration; however, spraying withpaclobutrazol in proper concentration only led to opposite results. The concentration in proper range of GA3 was negatively related with the flowering duration of the three species with notable level P < 0.05 or P < 0.01 whereas the concentration of paclobutrazol was positively related with the flowering duration of the species of which displayed notable level P < 0.01.
