摘要: 在人工模拟逆境生态条件下,测定了李6个种17个品种(系)细胞质膜差别透性、POD同工酶活性及叶片中可溶性糖含量.结果表明,叶片可溶性糖含量与枝皮细胞质膜低温伤害程度之间呈极显著负相关,枝皮POD同工酶活性与叶片细胞质膜高温伤害程度之间存在显著负相关性根据Fuzzy综合评判,对不同种类品种的综合抗逆性进行了评价.

Abstract: The relative electric conductivity, soluble sugar content in leaf, and PODactivity of 17 plum varieties, which belong to six species and one genera, were measured under artificial adverse environments. The results showed that there were extreme significant negative correlation (α=0.01) between soluble sugar content and membrane freezing damage, and significant negative correlation (α=0.05) between POD activity in bark and leaf cell heat damage. According to Fuzzy synthetic evaluation, the comprehensive resistances of different plum varieties to adverse circumstances were discussed in this paper.
