摘 要：
通过对正常生长条件下的一年生油梨实生幼苗进行光合诱导 ,在最适光照强度为 50 0μmol·m-2·s-1下测定了土壤水分胁迫对其光合作用强度的影响及光合色素含量的动态变化。结果表明 ,随着胁迫的加深 ,其光合作用明显下降。胡萝卜素首先明显下降 ,其后叶绿素 a也逐渐下降 ,而叶绿素 b表现为含量不断上升 ;H2 O2 含量先是迅速增加 ,而后呈下降的趋势

摘 要：
Photosynthetic inducement was done in one year old,normally growing avocado tree,the effects of water stress on intensity of photosynthesis and relative dynamic changes of photosynthetic pigments was determined under 500 μmol·m -2 ·s -1 .The results indicated:Its photosynthesis dropped clearly with stress intensified.Carotene dropped first,then did chlorophyll a,but chlorphyll b content increased constantly.H 2O 2 increased greatly then it had a decline trend.
