摘　　要：随机抽取100只同龄疣荔枝螺(Thais clavigera Kuster),开展其形态性状与体质量和软体部质量的相关与通径分析。实验选取并测量了壳长(X1)、壳宽(X2)、壳厚(X3)、壳口长(X4)和壳口宽(X5)等5项形态性状以及体质量(Y)和软体部质量(Z)等2项质量性状,运用相关分析、通径分析和多元回归分析等方法分析了各形态性状对体质量和软体部质量的影响。相关分析表明,疣荔枝螺各项性状间的相关均呈极显著(P<0.01)。通径分析表明,形态性状对体质量直接影响大小的顺序为壳长(0.459)>壳宽(0.277)>壳厚(0.209)>壳口宽(0.140);壳长对体质量的直接决定系数最大(0.220),是影响体质量的主要因素。通过多元回归分析,建立了形态性状对体质量的回归方程:Y=-9.714+0.220X1+0.204X2+0.195X3+0.151X5。In this study, 100 individuals of Thais clavigerawere used to analyze the correlationsamong morphological traits and body mass and soft body mass. Body mass(Y), soft body mass(Z) and five morphological traits includingshell length(X1), shell width(X2), shell thickness(X3), shell length(X4) and shell width(X5) were measured. The effects of various morphological traits on body mass and soft body were analyzed through correlation, path and multiple regression analyses. The correlations among the traits of Periwinkle were extremely significant(P<0.01). The direct influence of morphological traits on body mass ranged from shell length(0.459) to shell width(0.277), shell thickness(0.209) to shell width(0.140) with the shell length the most dominant factor of body mass. The regression equation of morphological traits to body mass was Y=-9.714+0.220X1+0.204X2+0.195X3 +0.151X5.
