| 摘 要： | 为深入了解5-氨基乙酰丙酸（ALA）对西葫芦生长影响的光合生理机理，以‘早青一代’西葫芦为材料，研究ALA对低温胁迫下西葫芦幼苗光合特性的影响。结果表明，低温胁迫下，西葫芦幼苗叶绿素含量显著降低，净光合速率显著降低，单株叶面积和物质积累极显著减少；60 mg/L的ALA可以减缓低温胁迫对西葫芦幼苗的影响，使总叶绿素含量增加29.96%，净光合速率（Pn）增加52.96%，叶面积增加39.80%，单株物质积累增加43.75%。60 mg/L的ALA缓解低温胁迫对西葫芦幼苗的影响主要是通过叶绿素的增加和非气孔因素实现的。 |

| Abstract: | In order to utility ALA in summer squash,we need a better understanding of the mechanism of ALA to photosynthetic and physiological characteristic of summer squash.Using ' Zaoqingyidai ' as experiment material,an experiment was conducted to examine the effects of 5-aminolevulinic acid (ALA) on photosynthetic characteristics of leaves of summer squash seedlings under chilling stress.The results were as follows:Under chilling stress,the chlorophyll contents decreased,net photosynthesis rate (Pn),leaf area and... |
