| 摘 要： | 在黄淮地区冬季自然低温条件下,以4个不同抗寒类型的冬小麦品种为材料,测定了不同播种深度下冬小麦的抗寒生理指标。结果表明,在4 cm和6 cm播种深度下,抗寒性弱的品种细胞质膜透性和MAD含量低于抗寒性强的品种;在6 cm播种深度下,抗寒性强的品种SOD活性、Pro含量明显高于抗寒性弱的品种;在4 cm播种深度下,抗寒性强的品种POD活性高于抗寒性弱的品种。即在4 cm和6 cm播种深度下,小麦的抗寒性最强。从4个小麦品种SOD活性的变化看,京冬841的SOD活性明显高于其它3个品种。

| Abstract: | In order to understand the physiological characteristics of wheat resistance changes,in the winter Huanghuai natural low-temperature conditions,the four different types of winter wheat varieties for resistance materials,different planting depth of cold Determination of physiological indicators.The results showed that strong winter hardiness of the cell membrane permeability and MDA content were significantly lower than the weak species when the sowing depth of 4 cm and 6cm.At 6 cm depth of planting,the stro... |
