外源脱落酸、水杨酸对小麦种子萌发及生理特性的影响

Abstract:
穗发芽严重降低籽粒产量、品质和种用价值，是小麦育种和生产急需解决的难题.为利用发芽抑制剂的化控途径有效防治穗发芽，研究了不同浓度的外源激素脱落酸（aba）、水杨酸（sa）对种子发芽的抑制作用及其生理生化响应.结果表明：浓度大于70mgl-1aba和大于4mmoll-1sa均不同程度地抑制种子发芽并表现剂量效应，赤霉素对二者有拮抗作用，70mgl-1aba＋8.0mmoll-1sa对小麦普遍具有强烈的发芽抑制效应；aba阻抑种子发芽是一种延缓作用，受基因型影响较大；sa对不同基因型有强烈的休眠促进作用，并显著提高种子对aba的敏感性（p＜0.01）；种子萌发过程中，两种激素均诱导籽粒α-淀粉酶和ppo活性下降，且sa处理组的酶活性降幅更大；aba明显促进种子pal活性，而sa处理组的pal活性水平最低.因此，aba与sa的发芽抑制效应与作用方式不同，sa增强种子的aba敏感性，二者组合产生了良好、稳定的发芽抑制效果.
