| 探讨γ-氨基丁酸(GABA)采后处理对芒果果实品质的影响,为寻找芒果采后保鲜新技术提供理论依据。以‘贵妃’芒果为试材,研究2.0 mmol/L的GABA采后处理对芒果在常温贮藏期间果皮色泽、果实硬度、Vc、TSS、淀粉、可溶性糖和有机酸含量以及自然发病率和病情指数的影响。结果表明,GABA采后处理抑制了芒果果皮L值和b值的增大,促进贮藏前期a值的增大；延缓了芒果贮藏前期果实硬度和淀粉含量的降低、TSS和可溶性糖含量的上升,并提高了中后期TSS和可溶性糖含量；同时,GABA可延缓果实Vc、柠檬酸、莽草酸及总酸含量的降低,并提高贮藏中后期苹果酸和奎宁酸的含量；另外,GABA降低了贮藏期间果实自然发病率和病情指数。因此,GABA采后处理能有效保持芒果果实的采后品质。 |

| Effect of GABA postharvest treatment on the quality of mango fruit was investigated to provide a theoretical basis for looking for new postharvest preservation technology of mango fruit. The ‘Guifei’ mango fruit was used as test material to study the effects of 2.0 mmol/L GABA postharvest treatment on the fruit peel color, fruit hardness, vitamin C, soluble solids, starch, soluble sugars and organic acids contents, as well as natural incidence rate and disease index of mango fruit during storage at room temperature. The results showed that GABA postharvest treatment inhibited the increase of L and b values, promoted the increase of a value in mango peel in the early storage stage. GABA treatment delayed the decrease in fruit hardness and starch content, as well as the increase in soluble solid and soluble sugar contents in the early stage of storage, and increased the contents of soluble solids and soluble sugars in mango fruits in the middle and later stages of storage. Meanwhile, GABA postharvest treatment can delay the decrease of vitamin C, citric acid, shikimic acid, and total acid contents, and increase the contents of malic acid and quinic acid in mango fruit in the middle and later stages of storage. In addition, GABA postharvest treatment reduced the natural incidence rate and disease index of mango fruits during storage. Therefore, GABA postharvest treatment can effectively maintain the postharvest quality of mango fruit. |
