| 摘 要： | 通过对孜然芹的7个产量构成因素进行相关分析、通径分析和回归分析。相关分析的结果表明，单株产量与复伞形花序数、小伞形花序数、分枝数、有效分枝数、株粒数及千粒重具极显著正相关，相关系数依次为0．9040＊＊，0．8860＊＊，0．8409＊＊，0．8336＊＊，0．8659＊＊，0．3925＊＊。回归分析和通径分析结果表明，株高、分枝数、株粒数和千粒重是影响孜然芹单株产量的关键因素，其中株粒数、千粒重对单株产量的直接作用较大。

| Abstract: | Analysis on the correlation,path and regression analysis were studied with Cuminum cyminum L.The results showed that there were very significant correlation between single plant yield and the number of compound umbels,umbellules,branches,effective branches,seed number per plant and thousand-grain weight,their correlation coefficients were 0.9040~(**),0.8860~(**),0.8409~(**),0.8336~(**),0.8659~(**) and 0.3925~(**)respectively.The results of regression and path analysis indicated that plant height,number of branches,seed number per plant and thousand-grain weight were important factors for single plant yield,and the direct effects of seed number per plant and thousand-grain weight were stronger than that of plant height and number of branches. |
