以内蒙古扎兰屯地区山杏为试材,通过对其群体性状进行研究,调查树体因子、正态性检验和相关性分析。结果表明:28个山杏数量性状呈正态分布,其中变异系数最大的为嫩枝长,达48.7%;叶柄长、完全花比例、嫩枝粗、叶宽、叶柄粗、核重等变异系数均超过20%。核重、仁重与嫩枝粗、节间长度、叶长、叶宽、叶柄长、叶柄粗、核长、核宽、仁长、仁宽和果重显著相关;出核率与果厚显著相关,出仁率与核宽、核厚、仁厚和核重显著相关。综合变异性分析和相关性分析,确定嫩枝长、嫩枝粗、节间长度、叶形指数、果重、果厚作为当地山杏间接选种的主要数量性状指标。
In order to study the population traits, the arborvitae apricot in Zhalantun area of Inner Mongolia was used to investigate the tree body factors, normality test and correlation analysis. The results showed that the quantitative traits of 28 wild apricots showed a normal distribution, with the biggest variation coefficient being 48.7% of shoot length; the variation coefficient of petiole length, complete flower proportion, shoot diameter, leaf width, More than 20%. Kernel weight, kernel weight and shoot diameter, internode length, leaf length, leaf width, petiole length, petiole thickness, kernel length, kernel width, kernel length, kernel width and fruit weight were significantly correlated Related, kernel rate and nuclear width, nuclear thickness, thickness and nuclear weight were significantly correlated. Comprehensive variation analysis and correlation analysis to determine the length of shoots, shoots, internode length, leaf index, fruit weight, fruit thick as an indirect selection of the main characters of the local apricot.
