摘　　要：根据2016年对带岭矮化落叶松种子园的调查材料,运用二元线性回归和相关分析的方法,统计出标准2年生长枝上的短枝数量结构与初始嫁接接穗的直径及其所在小环境透光率结构的二元线性回归方程模型:^y=-29.38+366.67x1+39.91x2,复相关系数ry.1.2=0.922;雌花数量结构与短枝数量结构的相关系数r=0.848。据此可根据高枝嫁接矮化兴安落叶松种子园标准株的短枝数量结构与初始嫁接接穗的直径结构预测其种子的产量。同时揭示了兴安落叶松丰产结实光照条件的透光率达到50%即可。Based on the investigation in seed orchard of dwarfing Larix gmelinii in Dailing in 2016, the binary linear regression equation for the relationship among the quantity and structure of dwarf shoot in the standard two - year branches, scion diameter of initial grafting and transmittance in small environment is y = - 29. 38 ＋ 366. 67x1 ＋ 39.91x2,the multiple correlation coefficient is ry.1.2 = 0. 922, and the correlation coefficient of the quantitative structure of female and dwarf shoot is r = 0. 848. The yield of seed can be predicted by use of the quantitative struc- ture of dwarf shoot and the diameter of initial grafting of standard branches. And the transmittance of light condition is 50% for high yielding and fruiting of Larix gmelinii.
