摘　　要：以1a生草本醉蝶花为材料，研究叶面喷施不同浓度的多效唑对其生长和开花的影响。结果表明：与对照组相比，随着处理浓度的增加，其它处理组植株株高、主茎高随之降低，且处理浓度越高与对照组相比差异越显著；基径除1000mg／L处理外，其它处理组与对照组相比均无显著差异；主花枝长也无显著差异；花枝基茎随浓度增大，差异性越显著；在群落水平上，与对照组相比，其它处理组的花蕾期和盛花期与对照相比差异不大，而始花期和凋谢期均有一定时间的推迟和延长，各处理始花期比对照推迟了6～9d不等；凋谢期比对照延长了14-24d不等；其中盛花期持续时间和平均每株的花数量均以800mg／L为最好。One-year Cleome spinosa L. was used to study on the growth and florescence with foliar spraying paclbutrazole with different concentrations. The results showed that with the increasing of concentration, the plant height and the length of main stem had decreased. Compared with the control treatment, the higher the concentration, the more significant differences between, so the flower branch diameter was. For the stem diameter, there were no significant differenees except the 1 000 mg/L treatment. What is more, so the length of main flower branch was. In the population level, in the flowering phenology of each treatment the bud date and median date were no significant differences, compared with the control treatment ; and the onset date and falling date were both a certain time delay and extension, the onset date of each treatment delayed ranged from 6 to 9 days and falling date ranged from 14 to 24 days, compared with the control; and the 800 mg/L treatment was the best concentration in duration time of the median date and the number of flowers on average per plant.
