摘要
采用电导法对赤霉素(GA3)处理后燕麦膜透性的变化情况进行研究,对10个燕麦品种(系)抗寒性进行比较。两种浓度GA3处理其电解质透出率相对较低。0mg/L浓度与100mg/L、250mg/L浓度处理间差异极显著。GA3使燕麦叶片电解质透出率降低,对燕麦膜透性有稳定作用。不同燕麦品种(系)对GA3的反应敏感程度不同。本次实验中GA3作用的持续时间较长。
Membrane permeability under cold condition of oats(Avena sativa L.),which were treated with Gibberelic acid(GA3),was measured by electrical conductivity method `and cold hardness was compared among 10 varieties.The electrolyte leakage of treated oats was relatively lower.In comparing the effects of GA3 spraying ,we found there were significant differences(P<0.01) between both 0mg/L and 100mg/L,and 0mg/L and 250mg/L,The reactions of the varieties were varied to GA3 spraying.GA3 spraying decrease electrolyte leakage under low temperature,which implied that the membrane permeability was more steadier.The action of GA3 on oats had a longer duration in the experiment.
