中文摘要：

为根茎和交替的灌溉(AI ) 通俗化打一个生物基础，不同根茎上的葡萄藤 Malvasia grafted 的生长上的部分根地区弄干的效果(PRD ) 被调查。三联合上的 112 划分的根灌溉的生物效果，即， Malvasia/420A， Malvasia/3309C，和 Malvasidl 10R，被关木头的植物学习。所有植物为不同灌溉策略被分开成三个组。在灌溉替换物的植物的新生根的集体生长被大约 7.8-22.2% 显著地比井高支持 -- 浇的。然而，新射击生长，特别内部节点被交替的灌溉减少。所有三联合的平均根射击比率从 1.1 ～ 1.46 被增加。新生根生长并且内部节点长度被固定的部分根地区灌溉(FI ) 在不同数量减少，在 37.9 和 36.9% 点的 M/3309C，在 18.4 和 22.5% 点的 M/llOR 分别地。在 FI 下面的所有三联合的全部的生物资源与浇得好的相比以 19.2-34.3% 的率减少了。葡萄藤的水压力改编主要取决于根茎。llOR 比水里的 3309C 和 420A 强调改编是更有效的。PRD-A1 有益于根生长，因此改进了葡萄藤的干旱抵抗的能力。

英文摘要：

To lay a biological foundation for rootstocks and alternate irrigation （AI） popularization, the effects of partial rootzone drying （PRD） on the growth of the grapevine Malvasia grafted on different rootstocks were investigated. Biological effects of 1/2 divided root irrigation on three combinations, i.e., Malvasia/420A, Malvasia/3309C, and Malvasia/110R, were studied by wood-boxed plants. All the plants were separated into three groups for different irrigation strategies. Mass growth of new root in alternate-irrigated plants was remarkably promoted by about 7.8-22.2% higher than the well- watered ones. However, new shoot growth, especially the internode was reduced by alternate irrigation. The average root-shoot ratio of all the three combinations was increased from 1.1 to 1.46. New root growth and internode length were decreased by fixed partial rootzone irrigation （FI） at different amount, M/3309C at 37.9 and 36.9%, M/110R at 18.4 and 22.5%, respectively. Total biomass of all the three combinations under FI decreased at the rate of 19.2-34.3% compared with well-watered ones. Water stress adaptation of grapevine mainly depends on rootstock. 110R is more efficient than 3309C and 420A in water stress adaptation. PRD-AI benefited root growth, thus improved the drought-resistant ability of grapevine.
