摘要: 比较小麦耐盐突变体近等基因系的钾离子含量及其与SOD活性的相关性分析,结果表明:耐盐性不同的近等基因系之间钾离子含量存在着显著差异,耐盐性强的RH8706-9含钾量最高;分别为耐盐性差的H8706-3、H8706-58的3.572倍和3.167倍.小麦功能叶片的SOD活性与钾含量呈极显著线性正相关.进而表明,小麦耐盐性强弱与旗叶叶片含钾量的多少在一定范围内呈正相关,钾可能参与了SOD的活性调节.

关键词: 近等基因系小麦, 钾离子含量, SOD活性, 耐盐性

Abstract: The K+contents of wheat salt-tolerance mutants were measured and the correlation analysis was carried out. The results showed that the K+content of different wheat salt-tolerance mutants was greatly different. The K+content of strong salt-tolerance mutant RH 8706-49 was highest, It is 3.572 times of the H8706-34 s and 3.167 times of the H8706-58 s. There is significant linearity positive correlation between the SOD activity and the K+content in the function leaves of wheat. We can make the conclusion that there is a positive correlation between the K+content and the salt-tolerance of wheat.Therefore, K+is probably involved participated in the regulation of the SOD activity.

Key words: Near-isogenic line wheat, K+content, SOD activity, Salt-tolerance
