新疆6个欧洲李品种休眠枝抗寒性研究
Cold Resistance of Dormant Branches of Six European Plume Varieties in Xinjiang
摘要
Abstract
To investigate the differences in cold resistance of different European plum varieties in Xin-jiang,this experiment was conducted using the varieties of'Stanley','Tacheng Suanmei','Frence','Richard Early','Empress'and'President'.The changes of cold resistance related indexes in dormant an-nual branches of the six European plum varieties were investigated under low temperature stress treatments,their semi-lethal temperatures were calculated,and their cold resistance was evaluated using the method of membership function.The results showed that the semi-lethal temperature of the branches of the six varieties were-30.88 ℃('Tacheng Suanmei'),-25.34 ℃('Richard Early'),-24.25 ℃('Frence'),-24.24 ℃('President'),-23.45 ℃('Stanley'),and-22.56 ℃('Empress').As the stress temperature de-creased,the relative conductivity of dormant branches of the six European plums showed an increasing trend,the malondialdehyde content showed an increasing-decreasing-increasing-decreasing trend,the soluble protein and proline contents showed the trend of first increasing and then decreasing,the soluble sugar content showed a trend of first decreasing and then increasing,the superoxide dismutase(SOD)and catalase(CAT)activi-ties showed the trend of increasing-decreasing-increasing,while the peroxidase(POD)activity showed first increasing and then decreasing.Eight indexes were selected for the comprehensive evaluation by membership function method,and the results showed that the cold resistance of the six European plum varieties was ordered as'Tacheng Suanmei'＞'Richard Early'＞'President'＞'Stanley'＞'Frence'＞'Empress'.关键词
