| 摘 要： | 目的：探讨不同时期剪枝处理对桔梗结实特性的影响，找出促进桔梗种子生长发育的适宜时期，为桔梗的繁种提供参考。方法：一年生种苗，大田栽植，现蕾后剪枝处理，田间观察记载剪枝后开花与果实成熟进程，测定株高、分枝数、坐果数、千粒重等。结果：剪枝处理的开花期依次后移，株高显著降低，分枝数增多，单株坐果数减少，对种子的千粒重有明显影响。结论：对二年生繁种桔梗，其适宜的剪枝时期在6月20日至7月5日之间。 |

| Abstract: | Objective: To investigate the effects of top pruning on fruiting characters of Platycodon grandiflorum, and find the suitable stage, in which seed growth and development furtherly. Method: One-year old seedlings were chosen and planted in field. Plant height, branching number, fruit number per plant, 1 000 grains weight were measured during growth and development period, respectively. Result: The treatment of top pruning postponed in turn the flowering date, lowered the plant heights and the fruit number per plant, increased the branching number and influenced significantly on 1 000 grains weights. Conclusion: The suitable stage of top pruning for producing seeds was from June 20th to July 5th. |
