| 摘 要： | 为分析抗寒性不同的冬麦品种在低温驯化期适应性的差异,以两个冬小麦品种为材料,在低温驯化期测定叶片和分蘖节处的生理指标。结果表明,抗寒性较强的东农冬麦1号的电导率低于济麦22;在低温驯化期,两个品种脯氨酸和可溶性蛋白含量均有升高,其中东农冬麦1号两个部位的脯氨酸和可溶性蛋白含量均高于济麦22。

| Abstract: | To analyze the distinctions in adaption during cold acclimation period among the cultivars which were different in the cold resistance, the physiological traits in the leaves and tiller nods of two kinds of winter wheat cultivars during the cold acclimation period were observed and measured. The results showed that the electrical conductivity of the cold resistant cultivar Dongnong Dongmai1 was lower than that of Jimai22; the content of proline and the soluble protein of both cultivars increased during the cold acclimation period, and the content of proline and the soluble protein in leaves and tiller nods of the Dongnong Dongmai1 was higher than that of Jimai22. |
