摘　　要：本实验选取管花蒲公英种子在实验室条件下种植,当幼苗长到5-6片真叶时进行水分胁迫处理,结果表明:水分协迫组植株比正常植株的POD活性和脯氨酸含量高,而且随着胁迫时间的增加,POD活性和脯氨酸含量也随之增加。The seeds of Neo - Taraxacum siphonanthum were planted in the terms of laboratory, The sprout were handled under water stress when they have 5 - 6leaves.The results indicated that the activities of water stress plants is higher than the normal groups, the contents of free proline is also higher,The activity of POD and the contents of free proline also grow with the creasing of the time of water.
