摘要
选用2个强优势组合(9514、9518)及其亲本为材料,就其有关生理生化指标进行测定分析。结果表明:可以利用黄瓜子叶叶绿素含量、POD活性作为早期预测黄瓜杂种优势的一个辅助手段。而SOD活性可否作为早期预测黄瓜杂种优势的一个参考依据,有待于进一步验证。
Two crosses （9514, 9518） with excellent heterosis and their parents were used in the experiment. Some physiological and biochemical characteristics were measured and compared between the crosses and their parents. The results showed：the content of the cotyledon chlorophyll and enzyme activity of POD could be regarded as a reference index to predict the heterosis of the cucumber. However, further experiment should be made to determine whether SOD activity could be used to predict heterosis of cucumber.
