摘要: 以管花蒲公英为材料,研究盐分胁迫对其的生理影响及水杨酸对盐胁迫条件下的管花蒲公英的保护作用。结果表明:水杨酸能够降低盐胁迫条件下相对电导率,提高体内过氧化物酶等细胞保护性酶的活性;提高可溶性糖和可溶性蛋白的含量,提高管花蒲公英对盐胁迫的抗逆性。

Abstract: Responses of dandelion to salt stress and protection of salicylic acid on salt stressinduced injuries were studied. The result showed that, salicylic acid can decrease the leaf’s relative conductivity, promote the activity of membrane protective enzymes such as POD; The content of solubility carbohydrate and solubility protein were increased. Therefore, the injuries of salt stress in dandelion were protection and the adaptabilities of dandelion to salt stress were raised.

Key words: salt stress, salicylic acid, protection, Neo-Taraxacum siphonanthum
