以甘肃河西走廊日光温室主栽辣椒品种(陇椒2号)为试材,采用盆栽控水的方法,研究了干旱胁迫下喷施外源 ALA 提高辣椒幼苗抗旱性的效应。研究结果表明,与喷清水对照相比,外源 ALA 提高了干旱胁迫下辣椒幼苗叶片可溶性糖、叶绿素含量,超氧化物歧化酶(SOD)和过氧化物酶(POD)活性,而丙二醛(MDA)含量则相反,表明喷施外源 ALA 能提高辣椒幼苗的抗旱性。
以甘肅河西走廊日光溫室主栽辣椒品種(隴椒2號)為試材,採用盆栽控水的方法,研究瞭榦旱脅迫下噴施外源 ALA 提高辣椒幼苗抗旱性的效應。研究結果錶明,與噴清水對照相比,外源 ALA 提高瞭榦旱脅迫下辣椒幼苗葉片可溶性糖、葉綠素含量,超氧化物歧化酶(SOD)和過氧化物酶(POD)活性,而丙二醛(MDA)含量則相反,錶明噴施外源 ALA 能提高辣椒幼苗的抗旱性。

Using the major pepper cultivar Longjiao No.2 for heliogreenhouse planting in Hexi corridor of Gansu, we studied the effects of spraying exogenous ALA on improving drought stress of pepper seedlings in pots by controlling water usage. The results showed that, compared with the control treatment (spaying clear water), spraying exogenous ALA could significantly improve the soluble sugar content, chlorophyll content, SOD activity and POD activity, and lowered MDA content, which indicated that spraying exogenous ALA could improve the drought resistance of pepper seedlings.
