| 中文摘要: |
| 以葡萄品种‘玫瑰蜜’为试材，通过对主干进行一次和二次环剥，研究了对其果实大小、果皮色素、果肉营养物质含量及其形成规律的影响。结果表明，在果实成熟过程中，果皮叶绿素、可滴定酸的含量均逐渐降低，类胡萝卜素、花色苷、总酚、总黄酮及果实各种营养物质含量均逐渐上升，而淀粉和钾的含量则先升高后降低。环剥不仅能够显著提高果皮类胡萝卜素、花青苷、总酚、总黄酮和果汁可溶性固形物的含量，而且还能显著降低果汁可滴定酸、维生素C的含量，增加固酸比。环剥后，果实可溶性糖、葡萄糖、可溶性蛋白质、总氮、磷和钾的含量均显著升高，而铁、锌和铜的含量则显著降低。此外，二次环剥显著增大了单果重、果实纵径和横径，而一次环剥则使其显著降低。主干一次和二次环剥均能显著提高玫瑰蜜葡萄的果实品质，在生产上，若用于鲜食可进行二次环剥，若用于酿酒则仅需一次环剥即可。 |
| 英文摘要: |
| Rose Honey grape variety were used to examine the effects on berry size, the contents of pericarp pigments and flesh nutrients and its change regularity by trunk-girdling once and twice. The results showed that the contents of chlorophyll and titratable acid reduced gradually, and the contents of carotenoid, anthocyanin, total phenols, total flavonoids and kinds of nutrient contents increased gradually during the process of fruits ripening, whereas the contents of starch and potassium increased firstly, then decreased again. Girdling could not only significantly improve the contents of carotenoid, anthocyanin, total phenols, total flavonoids and soluble solids content, but also significantly decrease the contents of titratable acid and vitamin C, increased solid acid ratio. The contents of soluble sugar, glucose, soluble protein, total nitrogen, phosphorus and potassium improved significantly after girdling, but the contents of iron, zinc and copper decreased significantly. Additionally, trunk-girdling twice could also significantly increase berry weight, length and diameter, whereas trunk-girdling once could decrease significantly the indices. Above all, trunk-girdling once and twice could significantly improve fruit quality of Rose Honey grape. Grapevine should be girdled twice for table grape and be girdled once for wine grape, in production. |
