生态因子对山茱萸开花习性的影响

Study of Effects of Ecological Factor on Flowering Habit of Cornus officinalis

摘要:

目的 :在山茱萸花期内,通过观察温、湿度的变化探索生态因子对其开花习性及开花的影响。 方法 :在山茱萸花期内连续5昼夜每隔2 h测量温度和湿度,同时记录其开花数。 结果 :山茱萸在1天中开花时间为6 ∶00-16 ∶00,花蕾开放85%以上在8 ∶00-14 ∶00; 开花的最适温度为10 ℃~14 ℃,湿度为45%~55%。 结论 :适宜的温湿度是山茱萸开花的必要条件,生态因子与山茱萸开花有着密切的关系。

Abstract:

Objective: In the florescence of Cornus officinalis ,we observe the change in temperature and humidity for exploring the relationship between ecological factors and the flowering habit of C. officinalis . Method: We measure temperature , humidity and the number of blooming every 2 h in the sequence 5 day and night of the florescence of C. officinalis . Result: we find that in a day,the blooming time of C. officinalis is from 6 ∶00 to 16 ∶00,and the blooming time is from 8 ∶00 to 14 ∶00 when more than 84 percent buds effloresced.The best temperature of blooming is from 10 ℃ to 14℃,and the needful humidity is from 45 percent to 55 percent. Conclusion: Appropriating temperature and humidity is a necessary condition for flowering of C. officinalis . So we think the ecological factors is closely related to flowering of C. officinalis .
