| 中文摘要: |
| 为探究茉莉酸甲酯对蓝莓贮藏品质的的影响。通过采后用不同浓度的茉莉酸甲酯处理蓝莓,在(0.5±0.5)℃冷藏条件下研究蓝莓生理品质变化,并结合主成分分析法对不同处理进行综合评价。结果表明：采后用茉莉酸甲酯处理均能不同程度低降低果实的腐烂率、呼吸强度及相对电导率,延缓蓝莓鲜果的硬度、VC含量、可滴定酸含量、可溶性固形物含量、花色苷含量及总酚含量的降低,降低蓝莓蓝莓果实PG活性和LOX活性。另外,主成分分析表明经过茉莉酸甲酯处理的蓝莓综合得分明显高于对照处理,并且300 μmol/L 茉莉酸甲酯处理的样品综合得分最高。因此,采后用300 μmol/L 茉莉酸甲酯对蓝莓果实的贮藏效果最好,能有效保持蓝莓的贮藏品质。 |

| The work aims to study the effect of Methyl jasmonate on the preservation effect of blueberry. The blueberry were treated with different concentrations of methyl jasmonate, the physiological quality changes of blueberry were studied under the condition of (0.5±0.5)℃ cold storage, and the principal component analysis method was used to comprehensively evaluate the different treatments. The results showed that the postharvest treatment with methyl jasmonate could reduce the decay rate, respiration intensity and relative conductivity of the blueberry fruits,and delay the decrease of hardness, VC content, titratable acid content, soluble solid content, anthocyanin content and total phenol content of blueberry fruits. The activity of polygalacturonase(PG) and lipoxygenase (LOX) were were significantly decreased. In addition, the principal component analysis showed that the comprehensive score of the blueberry treated with methyl jasmonate was significantly higher than that of the control treatment, and the comprehensive score of the sample treated with 300 μmol/L methyl jasmonate was the highest.Therefore, the effect of 300 μmol/L methyl jasmonate on the preservation effect of blueberry is the best, which can better maintain the storage quality of blueberry. |
