| 中文摘要: |
| 通过模拟西梅采后长途运输条件，探究振动胁迫后果霜覆盖率对其贮藏期间品质的影响，旨 在为西梅的产地商品化处理提供理论依据。以‘法兰西’西梅为试验材料，按照果霜覆盖率分为3个 等级，设置振动频率5 Hz，于4~6 ℃条件下振动8 h后，将其置于1~2 ℃下贮藏56 d，每8 d取一次样。 结果表明，果霜能明显改善西梅果实的色泽变化，延缓硬度、可溶性固形物（TSS）及可滴定酸（TA）含 量的下降，增强抗氧化酶活性，有效保持抗坏血酸（AsA）和谷胱甘肽（GSH）含量，减少超氧阴离子 （O2 - ）的生成，减缓过氧化氢（H2O2 ）含量、丙二醛（MDA）含量及细胞膜渗透率的增加。果霜对西梅采 后品质维持具有重要作用，能有效延缓果实细胞膜的氧化损伤及衰老软化。该研究将有助于进一步 认识西梅果实果霜的生物学功能，为制定有效的保鲜措施、延缓果实腐烂提供依据。 |
| 英文摘要: |
| The effects of fruit frosting coverage on the quality of prune during storage after vibration stress treatments were investigated by simulating the long-distance transportation conditions of prune after harvest, aiming to provide a theoretical basis for the commercialization of prune at the place of origin. The‘ France’ prunes were used as the test material, and the prunes were divided into three grades according to the frosting coverage rate. After vibration at a fre? quency of 5 Hz for 8 h at 4-6 ℃, the prunes were stored at 1-2 ℃ for 56 days, and samples were taken every 8 days. The results showed that the fruit frost could significantly improve the color change of prune fruits and delay the decline of firmness, soluble solids (TSS) and titratable acid (TA) contents, enhance the activity of antioxidant enzymes, effec? tively maintain the contents of ascorbic acid (AsA) and glutathione (GSH), reduce the formation of superoxide anion (O2 - ), and slow down the increase of hydrogen peroxide (H2O2) content, MDA content and cell membrane permeability. Which indicates that fruit frost plays an important role in postharvest quality maintenance of prune, and can effectively delay the oxidative damage and senescence softening of fruit cell membrane lipids. This study will help to further understand the biological function of prune fruit frost, and provide a basis for formulating effective preservation mea?sures to delay fruit decay. |
