| 摘 要： | 以酿酒葡萄品种六年生赤霞珠(Vitis vinifera L.cv.Cabernet Sauvignon)为试材,通过设置250、350、450、550 kg/667 m~24个负载量水平,研究不同负载量对单行倒L型整形下赤霞珠葡萄生长发育及果实品质的相关影响。结果表明,随着赤霞珠负载量的增加,赤霞珠单叶面积、新梢生长量和果实百粒重显著降低,果实主要品质指标还原糖、花色苷、总酚含量及糖酸比显著降低,总酸含量升高,单宁含量和pH呈现先升高后降低的变化趋势,不同负载量对类黄酮含量的影响没有明显的变化规律。

Effects of Fruit Loading on Grape Quality with Single Inverted L-Type Shape Shaping Method of Cabernet Sauvignon Grapevine |
| |
| Abstract: | Using 6-year-old Vitis vinifera L. cv. Cabernet sauvignon grapevine as the tested material, the effects of different load with single inverted L-type shape shaping method on its growth development and fruit quality were study by setting, four different fruit loads including 250, 350, 450 and 550 kg/667 m2. The results showed that with the increase of fruit loads, the leaf area, shoot growth and hundred-grain weight of grape decreased, the reducing sugar content, anthocyanin content, total phenol content and sugar-acid raito decreased, while the total acid content increased, the tannin content and pH increased firstly and then decreased; but the flavonoid content had no obvious change. |
