摘要
以四川省南充市金城山3个不同海拔高度(562m,640m和726m)的淫羊藿为研究对象,对其果实成熟的时间及数量进行了研究;同时也对其果实成熟量与大气湿度、温度、光照强度之间的关系进行了研究.相关的数据分析表明,淫羊藿果实成熟过程可分为初始期、高峰期和末期3个阶段.果实成熟主要受湿度,光照和温度的影响.气温的突变可能是促进淫羊藿果实成熟的机制之一;果实数与相对光照、温度之间都存在极显著的相关性.随着海拔高度的变化,淫羊藿果实成熟时间也有相应变化.由于淫羊藿果实成熟后易自裂,所以研究不同生境淫羊霍果实成熟时间的差异对于淫羊霍种子的采收也相当重要.
The fruit of Epimedium brevicornum was sampled from the Jincheng Mountain in Nanchong, Sichuan Province, China at 3 different altitudes of 562 m, 640 m and 726 m. The fruit maturity time and fruit quantity were studied, and the relationship of the matured quantity with humidity, temperature and illumination intensity was investigated. Results showed that the fruit maturity duration could be divided into three successive phases： starting, fastigium and terminal. The fruit maturity was significantly affected by humidity, temperature and illumination intensity. The variation in temperature might be one of the mechanisms that promote the maturity of E. brevicornum fruit. The quantity of the fruit was positively correlated with relative illumination intensity and temperature, respectively. The fruit maturity time was different at different altitudes. Because the fruit of E. brevicornum is easily split open after matured, it is very important to study the maturity time of E. brevicornum fruit at different altitudes and places for harvesting the fruit.
