  2. The quantity of increased leaf efficiency contributed to the aboveground biomass gain after defoliated are different at different irradiance. at the initial stage, the increased leaf efficiency of defoliated plants contributed more to biomass increment of aboveground under higher light level than those under lower irradiance. as the treatment time extended, the contribution to growth of increased leaf efficiency of plants under intermediate light level went beyond those under full irradiancy

    （ 2 ）葉受損的植株葉效率顯著高於未受損植株；光照強度越高，植株的葉效率越高；受損植株增加的葉效率在不同光照條件下對生長的貢獻大小不同，處理初期，全光照下葉損失植株增加葉效率對地上部分的生物量增加貢獻大於中度光照，大於低光照下植株，隨處理時間的延長，中度光照下的植株增加葉效率對生長的貢獻逐漸超過了全光照下植株。
