摘要
研究了在土壤自然干旱的水分胁迫条件下，干旱诱导的小麦叶片衰老与小麦叶片内源多胺水平之间的关系。结果表明，土壤干旱促进小麦幼苗衰老，不同处理间内源多胺水平与水分、蛋白质和核酸代谢之间存在一定的相关性，较高的内源多胺水平有利于小麦叶片在水分胁迫过程中保持较好的水分状况。
Relation of the levels of endogenous polymines (PAs) and senescence of leaves of wheat induced by drought was studied under water stress of natural soil drought.The results indicated that soil drought could bring about the senescence of wheat seedling,some correlations between the level of endogenous PAs and water status,protein and nucleic acid metabolism exised,and the high level of endogenous PAs might help in maintance of better water status in wheat leaves and in relief of hydrolysis of protein and nucleic acid during water stress.
