7月龄方斑东风螺形态性状对体质量的通径分析
Path analysis of the effects of morphometric attributes on the body weight of 7-month-old Babylonia areolata
摘要
Abstract
This study analyzed the relationship between 11 morphometric attributes (X1–X11) and the body weight (Y) of 7-month-old Babylonia areolata. The results showed highly significantly positive correlations between mor-phometric attributes and body weight (P<0.01). The path analysis revealed that X2displayed the highest positive direct effect (0.373) on body weight, followed by X7and X3. X10showed an indirect effect on body weight through X2,X3,and X7.The results of analysis of the determination coefficients revealed the total decision coefficient of four morphological attributes affecting body weight to be 0.852, indicating that these morphological attributes are the primary factors affecting body weight. Multiple regression equations established using multiple regression analysis revealed that all the morphometric attributes are the best models for the 7-month-old B. areolata, including Y =0.0034X22.5128, Y = 0.0034X32.4349, Y = 0.0015X72.5967, and Y = –6.4964 + 1.3293X10.关键词
