| 摘 要： | 本文采用50 mg·L^-1、100 mg·L^-1和200 mg·L^-1等3种浓度的多效唑喷施1%盐胁迫下的冷季型草坪草紫羊茅（Featua fubraL.）,以电导法测定叶片膜透性、茚三酮比色法测定叶片脯氨酸含量,探讨多效唑提高紫羊茅耐盐胁迫能力的效果。结果表明：只有50 mg·L^1浓度的多效唑可以使紫羊茅的脯氨酸含量极显著增高,但对膜透性的影响表现出随多效唑浓度增高膜透性也增高。

| Abstract: | In this experiment, we spraied 50 mg·L^-1 , 100 mg·L^-1 and 200 mg·L^-1 of PP333 on the turfgrass, red rescue （Featua fubra L）, under 1% salt stress, measured membrane permeability by conductivity method, and determined proline concentration by ninhydrin colorimetry, which evaluate the ability of PP333 improving salt -tolerance of the red fescue. The results showed that only 50 mg·L^-1 of PP333 could make the proline concentration of red fescue very significantly increase, but that the membrane permeability increasing as the concentration of PP333 rising. |
