摘要
山葡萄生产主栽品种左山一、双红、双优和左优红、用“贝达”做砧木硬枝劈接亲和力、生根率、移栽苗圃地成活率和成苗率高。出圃苗木根系大于自根扦插苗木,用于生产建园表现生长和树体成型快、比同品种硬枝“扦插树”提早一年进入盛果期。上述品种2～6年生“贝达”嫁接树的公顷产量比对照平均增产20.8%、有良好的生产性能和遗传稳定性。上述品种与“公酿一号”硬枝嫁接、表现接穗与砧木亲和力差、生根和成苗率低、生产建园开花株率和产量低、3～4年生树嫁接树出现满树开花坐果少、5～6年生树出现大量死亡。左山一和双红互做砧穗、左优红做接穗、左山一和双红做砧木硬枝嫁接的催根幼苗表现为“假活”、不能育出苗木。
Study was carried out on high affinity and rooting rate of cleft grafting of hard branch and high viability rate of plants and plants percent transplanted into nursery garden among the varieties of ＂Zuoshanyi＂, ＂Shuanghong＂, ＂Shuangyou＂ and ＂Zuoyouhong＂ of Vitis arnurensis rupr. （v. a. r. ） mainly planted. Root sizes of plants out of nursery garden were bigger than that of self-root, which growth and trees taking shape were faster and one year earlier into full fruit period than those of self-root trees. Yielding per hectare of 2～6 years＂ grafting trees of those varieties of v. a.r. used ＂beta＂ as stocks was 20.8% higher than that of selfroot trees and which trees had good productive capacities and hereditary stability. Cleft graft of hard branch of those varieties used ＂Gongniang No. 1＂ as stocks showed low affinity of stock and scion, rooting rate, plant percent, bloom percent and yield in a productive garden, 3～4 year-old graft trees showed low fruit while full bloom, 5～6 year-old graft trees showed a large mount of death. Treatment of ＂Zuoshangyi＂ and ＂ Shuanghong＂ as stocks and scions for each other and treatment of ＂Zuoyouhong＂ as scions, ＂Zuoshangyi＂ and ＂Shuanghong＂ as stocks respectively showed ＂false living＂ and no plants.
