我区核桃栽培历史悠久,但生产中品系繁杂,优系极少,亟待解决品种规范化和良种化问题。我们试从芽接入手,探索核桃的芽接适期及为同砧木与接穗亲和力等因子对芽接的影响,以提高芽接效率,加速核桃良种化进程。 一、材料与方法 试验于1978年在乌什县九源泉果园核桃苗圃进行。供试砧木为31、41、317等三个优株的二年生实生苗,接穗分别采自831、417、418、961、96、91、63、44及241等优株,芽接时间分别为6月12—13日、6月20—21日、6月26—27日、7月19—20日、8
Walnut cultivation in our region has a long history, but the production of complex strains, very few excellent system, the urgent need to solve the problem of varieties of standardization and varieties. We try to start from bud hand, to explore the appropriate period of walnut budding and for the same rootstock and scion affinity and other factors on budding, in order to improve budding efficiency, speed up the process of walnut breeding. First, the material and method test in 1978 in Wushu County, nine orchard walnut nursery. The tested rootstocks were perennial seedlings of three excellent strains of 31, 41, 317 and the scion were collected from 831, 417, 418, 961, 96, 91, 63, 44 and 241, respectively, and their budding time was June December 12-13, June 20-21, June 26-27, July 19-20, 8
