摘要:
利用叶面喷施方法,探讨100 μmol/L外施褪黑素(MEL)溶液对低温胁迫下不同葡萄品种抗氧化酶系统和抗坏血酸-谷胱甘肽循环(AsA-GSH循环)的影响,以此推论MEL在葡萄受到低温胁迫时起到的作用。结果表明,外源MEL可以促进低温胁迫下葡萄抗坏血酸(AsA)和谷胱甘肽(GSH)含量的积累,降低GSSG含量。长时间(7 h)低温胁迫下,外源MEL可以降低脱氢抗坏血酸还原酶(DHAR)含量,能够维持较高的AsA-GSH循环系统中抗坏血酸过氧化物酶(APX)、DHAR、单脱氢抗坏血酸还原酶(MDHAR)、谷胱甘肽还原酶(GR)活性。喷施外源MEL促进了低温胁迫下葡萄AsA-GSH循环快速而有效的运转,降低了低温胁迫对葡萄植株的氧化伤害,从而缓解了低温胁迫对葡萄幼苗的伤害作用。
