| 摘 要： | 在木枣白熟期分别用ABA、H2O2与NO供体硝普纳（SNP）喷洒果实，对其调控木枣果实成熟的生理基础进行了研究。结果显示用不同浓度的ABA，H2O2与SNP处理，枣果实中丙二醛（MDA）的含量明显升高，其中100 mg?L-1浓度时MDA含量为最高；Ca、Vc和β-胡萝卜素含量呈现先降低后升高再下降的趋势，其中75 mg?L-1浓度时Vc和β-胡萝卜素含量最高，50 mg?L-1时Ca含量最高；CAT和APX活性的变化呈现先升高后降低的趋势，75 mg?L-1时CAT和APX活性均最大；DNA含量的变化呈现先缓慢降低后升高再下降的趋势，ABA比H2O2、SNP处理对DNA含量影响更明显，100 mg?L-1时DNA含量最高。结论：ABA、H2O2与SNP对木枣果实发育成熟的影响效果较为明显，其生理效果在多方面表现基本一致，有加快木枣果实成熟衰老的作用。

Effects of ABA, H2O2 and NO on the ripening physiology inMu Jujube Fruit |
| |
| Abstract: | In Mu jujube white mature period, respectively spraying fruit by ABA, H2O2 and NO donor sodium nitroprusside (SNP), and then having to research its regulation of physiology characteristics of fruit ripening.The results showed; Using different concentrations of ABA, H2O2 and SNP treatment of jujube fruit, content of MDA was significantly increased in tissues , the content of malonaldehyde(MDA) is the highest on 100 mg? L-1; The content of Ca, VitC and beta carotene decreased after increasing and then decreasing trend.content of VitC and beta carotene was the highest on 75 mg? L-1, when 50 mg mg? L-1,the content of Ca was the highest; the activity changes of CAT and APX increased at first and then decreased in tissue, when 75mg? L-1, CAT and APX activity were the biggest; The content changes of DNA decreased slowly after increasing and then decreasing trend in tissues, compared with H2O2and SNP, the treatment effect of ABA is more obvious on the content of DNA, when 100 mg? L-1, the content of DNA was the highest. Conclusion; the treatmen effect of ABA , H2O2 and SNP on development mature of Mu jujube fruit is more obvious, its physiological effects is basically identical in many ways,accelerate the ripening and senescence of Mu jujube fruit. |
