| 摘 要： | 采用花盆种植冷蒿，通过剪掉不同比例的顶芽及不同枝条长度人为模拟采食行为，观测受损后构件再生生长速率。实验结果表明不同的年龄组、不同的生长季节、采食与对照间，构件的再生生长速率具有显著差异。

| Abstract: | The net production of Artemisia frigida population which were in different age groups, in different growth seasons and in different treatments were determined. The results were as follows: The regeneration capcity of the population tend to decline with the age increasing; In July, the regeneration capcity is higher than in August; When Artemisia frigida population is grazed, its regeneration capcity is even higher. |
