赤霉素对台农芒果保鲜效果的研究

以10年生台农芒果树为试验材料,研究了采前喷施不同浓度（0.3、0.5、1.0、2.0、3.0g/L）赤霉素（GA）对采后芒果贮藏品质和采后生理的影响。结果表明：与空白对照相比,几种浓度的GA处理都能够延缓叶绿素的降解和类胡萝卜素及花青素积累,其中2.0g/L处理效果最显著;GA处理能够延缓果实病害发生,与对照相比,贮藏30d,0.5g/L处理可降低病情指数19.44%,处理间差异显著;GA处理能够延缓总可溶性固形物（TSS）含量的变化;减少维生素C（Vc）的损失;保持果实较高的硬度及可滴定酸（TA）含量;GA处理能抑制丙二醛（MDA）的积累,以2.0g/L处理效果最好,贮藏36d,CK、0....

Summary:以10年生台农芒果树为试验材料,研究了采前喷施不同浓度（0.3、0.5、1.0、2.0、3.0g/L）赤霉素（GA）对采后芒果贮藏品质和采后生理的影响。结果表明：与空白对照相比,几种浓度的GA处理都能够延缓叶绿素的降解和类胡萝卜素及花青素积累,其中2.0g/L处理效果最显著;GA处理能够延缓果实病害发生,与对照相比,贮藏30d,0.5g/L处理可降低病情指数19.44%,处理间差异显著;GA处理能够延缓总可溶性固形物（TSS）含量的变化;减少维生素C（Vc）的损失;保持果实较高的硬度及可滴定酸（TA）含量;GA处理能抑制丙二醛（MDA）的积累,以2.0g/L处理效果最好,贮藏36d,CK、0.3、0.5、1.0、2.0、3.0g/L处理果实的MDA含量分别为45.454、40.103、37.884、34.462、27.045、39.174nmol/g,处理间差异显著。综合外观品质和内在品质,2.0g/LGA处理保鲜效果最好。

GA; mango; storage quality; postharvest physiology
Taking trees of 10 years old ‘ Tainong ＇ mango as the experiment materials,the effects of pre-harvest spraying treatment with gibberellic （GA） at different concentrations of 0.3,0.5,1.0,2.0 and 3.0 g/L on the storage quality and post-harvest physiology of fruits were researched. The results showed that,compared with control fruits,GA treatment could delay the degradation of chlorophyll and the accumulation of carotenoid and anthocyanin with the best concentration of 2.0 g/L ;GA treatment could decrease disease of fruits compared with the control,0.5 g/L treatment could reduce disease index to 19.44% on 30 storage day and there were significant differences among treatments （P〈0.05）;GA treatment could delay the change of TSS content,reduce
