摘要
在单一弱光、单一亚适温及亚适温弱光下测定了不同类型黄瓜苗期的生理性状。结果表明 ,欧亚杂交品种在 3种逆境下各项生理指标均较高 ,各类型黄瓜遇单一弱光和亚适温弱光后光合速率都有一个降低又逐渐回升的过程 ,而在单一亚适温时光合速率下降不大。欧洲品种在单一弱光下叶面积、叶绿素含量高于亚洲品种 ,亚洲品种在单一亚适温时表现好于欧洲品种 ,欧洲品种可适应短期的单一亚适温。
The physiological characters of the different type cucumber were tested under the poor light condition,lower temperature condition.The results indicated that the cross hybrid varieties between European and Asian have higher physiological indexes. There is a process of gradually increased after decreased for photosynthetic rate of each type of cucumber under the lower temperature and poor light condition. Under the poor light condition,the European type varieties have the larger leaf area and higher chlorophyll content than the Asian type varieties. Under the lower temperature condition,the Asian type varieties appeared better than the European type varieties. The European type varieties can adapt short period lower temperature condition.
