摘要
在木枣白熟期,用不同的植物激素处理果实,通过检测其生理生化变化,研究6-BA、IAA、GA3与ABA对枣果实成熟衰老的调控作用。结果显示,6-BA、IAA、GA3和ABA处理后枣果中DNA含量差异较为明显,其中,ABA和6-BA处理效果显著;GA3和IAA处理后枣组织中的丙二醛(MDA)含量明显低于对照组,6-BA和ABA处理则相反;除ABA处理外,枣组织中脯氨酸(Pro)含量明显低于对照组,维生素C(Vc)含量变化则相反;过氧化氢酶(CAT)活性表现差异很大,ABA和6-BA处理CAT活性显著高于对照组,IAA和GA3处理则相反。6-BA、IAA、GA3与ABA的生理作用在多方面表现为相互促进与互为拮抗的关系,有调控木枣果实成熟衰老的作用。
In white mature period of Mu jujube, treating the fruits with different plant hormones 6-BA, IAA, GA3 and ABA, the regulatory effect of them on the ripening and senescence of fruits were studied through the detection of physiological and biochemical changes. Results showed that : the contents of DNA in jujube fruit after 6-BA, IAA, GA3 and ABA treatment varied significantly, and the effects with ABA and 6-BA treatment were the most;the contents of MDA in jujube tissue after GA3 and IAA treatment were significantly lower than those in the control group, and the results after 6-BA and ABA treatment were contrary;the contents of proline in jujube tissue were significantly lower than those in the control group except ABA treatment, and the contents of Vc were in the opposite; the CAT activity differed greatly, the CAT activities with ABA and 6-BA treatment were significantly higher than those in the control group, and those with IAA and GA3 were contrary. In conclusion, the physiological role of 6-BA, IAA, GA3 and ABA presented as the mutual promotion and antagonists in many ways, and showed their regulations on ripening and senescence in Mu jujube fruit.
