摘要:

以'岳华'苹果为试材,采用不同浓度2,4-表油菜素内酯(EBR,0、0.02、0.05 mg · L-1)与茉莉酸甲酯(MeJA,0、20、50 mg · L-1)两两混合,采前30 d喷施果实一次,以喷施蒸馏水为对照,研究对贮藏过程中果实品质的影响。结果表明,20 mg · L-1 MeJA + 0.05 mg · L-1 EBR处理可延缓室温贮藏过程中果实内在品质的下降;乙烯生成速率较对照低17.4%,且乙烯合成基因MdACO1MdACS1和乙烯响应因子MdERF3的表达受到抑制;果实色差值及花青苷含量较对照分别提高7.3倍和1.4倍,且果皮中MdMYB1MdCHSMdDFRMdF3H的表达量增加。50 mg · L-1 MeJA + 0.05 mg · L-1 EBR处理显著提高了果实色差值及花青苷含量,而对其他指标作用效果不显著。综上所述,苹果果实发育期间进行20 mg · L-1 MeJA + 0.05 mg · L-1 EBR处理对于果实贮藏过程中内在品质维持和外观品质提高具有显著效果。

Abstract:

The purpose of this study was to explore the effects of brassinolides(EBR)and methyl jasmonate(MeJA)on apple fruit quality during storage. The'Yuehua'apple fruit was used as a test material at different concentrations of EBR(0,0.02,0.05 mg · L-1)with MeJA(0,20,50 mg · L-1) mixed in pairs,and sprayed once on the fruit 30 days before harvest,and distilled water was sprayed as the control. The results showed that the mixed treatment of 20 mg · L-1 MeJA + 0.05 mg · L-1 EBR could delay the fruit firmness,titratable acid content,ascorbic acid content and soluble solids content increase of 'Yuehua'fruit during storage at room temperature,and prolong the fruit storage period. At the same time,the production of ethylene was 17.4% lower than that of the control,and the expression of ethylene synthesis genes MdACO1,MdACS1 and ethylene response factor MdERF3 were inhibited. 20 mg · L-1 MeJA + 0.05 mg · L-1 EBR treatment increased the color difference and anthocyanin content of the fruit by 7.3 and 1.4 times compared with the control,respectively,and increased the expression of MdMYB1,MdCHS,MdDFR and MdF3H in the peel. Moreover,50 mg · L-1 MeJA + 0.05 mg · L-1 EBR treatment group significantly increased the color difference and anthocyanin content of the fruit;however,the effect on other indicators was not significant. In summary,the treatment of 20 mg · L-1 MeJA + 0.05 mg · L-1 during apple fruit development had a significant promoting effect on the maintenance of internal quality and the improvement of appearance quality during fruit storage.
