摘要
在人工模拟逆境条件下 ,测定了李 6个种 17个品种 (系 )细胞膜差别透性、过氧化物酶 (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膜低温伤害程度呈极显著负相关 ,枝皮POD同工酶活性与叶片细胞膜高温伤害程度之间存在显著负相关。根据Fuzzy综合评判 ,对李不同种间和中国李不同品种间的抗逆性强弱进行了综合评价。
The relative electric conductivity of leaf and one year old shoot bark cell under artificial adverse circumstances,soluble sugar content in leaf and POD activity in leaf and one year old shoot bark was tested in 17 plum va rieties which belong to six species and one genera hybrid.The comparison of resistance to adverse circumstances in di fferent species was done.The correlation of physiologic and biochemical characters tested above were analysed.The results showed that the significantly negative correlation existed between soluble sugar content and membrane freeze damage and significantly negative correlation existed between POD activity in bark and leaf cell heat damage.According to Fuzzy synthetical valuation the comprehensive resistance of plum species to adverse circumstances were discussed.
