应用相关与通径分析方法研究山楂幼树结果母枝产量、母枝粗度、母枝抽生结果新梢数,结果新梢叶片数、花序果个数、单果重等因素之间的关系。相关分析结果表明,与产量密切相关因素依次为:果个数(r=0.9672)、叶片数(r=0.8668),果枝数(r=0.8163)、母枝粗(r=0.6096);通径分析结果为:果个数对母枝产量具有决定性的正向直接作用(p=0.9785),而果枝数对产量具有决定性的负向直接作用(p=-0.1019)。 Correlation and path analysis methods were used to study the relationship between seedling yield and stem thickness of young hawthorn seedlings, number of new shoots of female parent shoots, number of shoots of new shoots, number of inflorescences and weight of single fruit. The results of correlation analysis showed that the factors closely related to the yield were: the number of fruit (r = 0.9672), the number of leaves (r = 0.8668), fruit branch number (r = 0.8163) The results showed that the number of fruit had a decisive positive direct effect on the yield of parent (p = 0.9785), while fruit number had a decisive negative direct effect on the yield (p = -0.1019).
