| 摘 要： | 随机抽取中国及日本海域的1龄青蛤(Cyclina shiensis)245个,分别测量其壳高、壳长、壳宽、韧带长、壳重及软体部重等形态学和生产性状,采用相关分析、通径分析、决定系数分析和多元回归分析方法,讨论了贝壳各形态性状对软体部重的影响.结果表明,青蛤的壳高对软体部重相关系数r1y和直接影响通径系数Pi分别达到了0.953和0.938,统计检验均达到了极显著水平(P<0.01).此外,壳高对软体部重的决定系数R12为0.9080,多元回归分析亦显示出青蛤的壳高与软体部重具有显著的相关性(P<0.01).实验结论认为,壳高对青蛤的生产性状影响最大,可以作为青蛤种质选育的重要甄别性状.

| Abstract: | A statistic study on the relationship between the phenotypic feature and the body weight was done on 245 samples of wild Cyclina sinensis collected randomly in China and Japan, using SPSS 13.0 package, in which the body weight was used as a dependent variable and other 6 morphological traits as independent variables, including shell height, shell length, shell width, ligament length, shell weight and total weight. The results show that only the coefficient between the body weight and the shell height is significant (P<0.01), the correlation index, path coefficients and determination coefficients are 0.953, 0.938 and 0.9080 respectively, indicating that the shell height is an important indicative trait for seed selection or breeding of C. sinensis. |
