摘　　要：为了了解海拔与核桃品种(系)生长状况的关系,根据引种对比试验的初选结果,进行7个品种(系)的12个海拔试验点的区域试验,采用随机区组双因素方差分析的方法,研究海拔对不同品种(系)4年生树地径、树高、冠径生长量的影响。结果表明:各处理组合中海拔、品种及海拔与品种交互间地径生长量差异效应非常显著或显著,但差异规律性不明显;树高生长量差异效应非常显著或显著;冠径差异极显著,海拔之间冠径差异不显著,海拔与品种的交互作用不明显。In order to learn relationship of altitude and varieties or strains of walnut, based on the preliminary selection results of introduction contrast experiment, seven varieties or strains were tested at 12 altitude regions, effects of altitude on increments of basal diameter, height, crown diameter of 4 years trees were researched, adopting the method of random block and two-factor variance analysis. The results indicate that difference of basal diameter increment is very signifi cance or signifi cance in different treatment combinations of altitude, variety（strain） and its interplay, but the regularity is not obvious. Difference of tree height increment is very signifi cance or signifi cance. Difference of crown diameter increment is very significance, but it is not significant among different altitudes, and the interplay between altitude and variety（strain） is not obvious.
