摘　　要：为芸豆的高产栽培提供科学参考。采用DPS软件对单株生物产量、株高、单株有效荚数、荚果长、百粒重进行多元回归分析和通径分析,研究其对芸豆产量的影响。株高对芸豆产量的影响呈负相关,单株有效荚数、荚果长、百粒重对芸豆产量的影响达极显著水平,单株生物产量对芸豆产量的影响最弱。单株有效荚果数、荚果长、百粒重与芸豆产量呈极显著正相关,相关系数分别为0.649 90、.527 5、0.865 5。百粒重、荚果长与单株有效荚数,株高与单株生物产量的互作效应对芸豆产量有明显影响。5个效应因子对芸豆产量的影响大小顺序为百粒重>单株有效荚果数>荚果长>单株生物产量>株高。芸豆的产量与单株生物产量、株高、单株有效荚数、荚果长、百粒重有显著的线性关系。The aim of the research was to provide scientific basis for high-yield cultivation of kidney bean.Based on the multiple regression analysis and path analysis,the effect biomass per plant,plant height,effective pods per plant,pod length and 100-grain weight on the yield of kidney bean was studied with DPS software.The effects of plant height on the yield of kidney bean showed negative relation,that of effective pods per plant,pod length and 100grain weight on the yield of kidney bean reached at extremely significant level and that of biomass per plant on the yield of kidney bean was weakest.Effective pods per plant,pod length and 100-grain weight showed extremely significantly positive relation with the yield of kidney bean,with their correlation coefficients of 0.649 9,0.527 5,0.865 5 respectively.The interaction effect among 100-grain weight,pod length and effective pods per plant and that between plant height and biomass per plant were obvious on the yield of kidney bean.The order of the effects of 5 factors on the yield of kidney bean was 100-grain weight 〉 effective pods per plant〉 pod length 〉 biomass per plant 〉 plant height.The yield of kidney bean had significant linear relationship with biomass per plant,plant height,effective pods per plant,pod length and 100-grain weight.
