摘　　要：研究了水分胁迫下亚精胺对小麦幼苗相对含水量、叶绿素总量、蛋白质含量和蛋白酶活性的影响。结果显示,亚精胺预处理延缓水分胁迫下小麦幼苗叶片含水量、叶绿素含量和蛋白质含量的下降,抑制蛋白酶活性的上升。表明亚精胺预处理对水分胁迫的小麦幼苗具有防衰抗旱的保护作用。The effects of spermidine on the content of water, chlorophyll, protein and protease activity in leaves of wheat seedlings under water stress were studied. Results showed that spermidine could alleviate distinctly the decline of water content, chlorophyll content and protein content, retard effectively the increase of protease activity. These results suggested that using of exogenous spermidine could have protective effects on delaying senescence and resisting drought of wheat seedlings under water stress.
