外源水杨酸对干旱胁迫下小冠花种子萌发及幼芽生理特性的影响OA北大核心CSCDCSTPCD
Effects of exogenous salicylic acid on seed germination and physiological characteristics of Coronilla varia under drought stress
以豆科牧草“绿宝石”小冠花为试材,研究PEG-6000(浓度8％和12％)模拟干旱胁迫下不同浓度外源水杨酸(0、0.5、1.0和2.0 mmol·L-1)对小冠花种子萌发和幼芽生理特性的影响.结果表明:0.5～1.0 mmol·L-1水杨酸显著提高了干旱胁迫下小冠花种子发芽率、发芽势、发芽指数、活力指数和芽长,12％PEG胁迫下1.0 mmol·L-1水杨酸处理小冠花幼芽干质量显著高于干旱处理.0.5～ 1.0 mmol·L-1水杨酸处理显著提高…查看全部>>
This research investigated the effects of different concentrations (0,0.5,1.0,2.0 mmol · L-1) of salicylic acid on the seed germination and physiological characteristics of legume forage Coronilla varia (cultivar ‘ Lvbaoshi’) under PEG-6000 (concentration 8％ and 12％) simulated drought stress.The results showed that under drought stress,0.5-1.0 mmol · L-1salicylic acid significantly increased germination percentage,germination vigour,germination index,v…查看全部>>
