Abstract：Ten local cucumber resources in Yantai with good comprehensive characters were treated with weak light at the seedling stage,then their growth indexes and the protective enzyme activity were analyzed to identify the weak light tolerance.The results showed that under the weak light stress,the plant height,stem diameter,plant height/stem diameter,specific leaf area and dry weight of cucumber germplasm resources Hy910 and Qx1018 had not significant difference with those in normal condition.While their POD and PPO activities were significantly higher than those in normal condition.The SOD activity of cucumber germplasm Qx1018 was significantly lower than that in normal condition.Comprehensive comparison showed that the cucumber germplasms Hy910 and Qx1018 were not sensitive to weak light stress.As a result,they had,to some extent,weak light tolerance and could be used as good weak light tolerant cucumber germplasm resources.
