| 摘 要： | 以酿酒葡萄‘赤霞珠(Vitis vinifera L.cv.Cabernet Sauvignon)’果实为试验材料,研究采后不同剂量UV-B对葡萄果实中多酚含量及PAL活性的影响,为人为调控葡萄果实乃至葡萄酒品质提供理论依据。以成熟葡萄果实进行UV-B照射0 min(对照)、15 min、30 min、45 min、60 min、120 min,并随机取样测定果实中总酚、黄烷醇类多酚及PAL活性,结果表明:采后UV-B处理能显著提高葡萄果实苯丙氨酸解氨酶(PAL)活性,诱导采后葡萄果实多酚类物质积累。

| Abstract: | Taking the harvested berries ofVitis vinifera L. cv. Cabernet Sauvignon as material, the effects of ultraviolet-B （UV-B） on the concentration of total polyphenol, flavanols and the activity of phenylalanine ammonia-lyase （PAL） were studied to provide a theoretical basis for the artificial regulation of quality of grape berry and wine. Harvested grape berries were exposed to UV-B for 0, 15, 30, 45, 60 and 120min respectively, then the concentration of total polyphenol, flavanols and the activity of PAL were determined. The results indicate that UV-B can significant increase PAL activity and induce the accumulation of polyphenol compounds. |
