以随机选取的500条宽体金线蛭为样本,运用SPSS13.0软件包中的双变量相关性分析(Bivari-ate)程序对宽体金线蛭种蛭体重、产卵茧量、卵茧重、出苗量等4个繁殖指标作统计分析。在对宽体金线蛭种蛭体重与产卵茧量、卵茧重、出苗量的两两相关性分析中得出:宽体金线蛭种蛭体重与产卵茧量、卵茧重、出苗量相关系数分别为0.8697、0.9351、0.6972,均呈极显著正相关;产卵茧量与卵茧重相关系数为-0.563,呈极显著负相关;卵茧重与出苗量、产卵茧量与出苗量之间的相关系数分别为0.8172、0.4873,均呈正相关。20~30g种蛭平均产卵茧量、平均卵茧重、平均出苗量分别为2.78个、2.24g、32.48条,为最适种蛭。
以隨機選取的500條寬體金線蛭為樣本,運用SPSS13.0軟件包中的雙變量相關性分析(Bivari-ate)程序對寬體金線蛭種蛭體重、產卵繭量、卵繭重、齣苗量等4箇繁殖指標作統計分析。在對寬體金線蛭種蛭體重與產卵繭量、卵繭重、齣苗量的兩兩相關性分析中得齣:寬體金線蛭種蛭體重與產卵繭量、卵繭重、齣苗量相關繫數分彆為0.8697、0.9351、0.6972,均呈極顯著正相關;產卵繭量與卵繭重相關繫數為-0.563,呈極顯著負相關;卵繭重與齣苗量、產卵繭量與齣苗量之間的相關繫數分彆為0.8172、0.4873,均呈正相關。20~30g種蛭平均產卵繭量、平均卵繭重、平均齣苗量分彆為2.78箇、2.24g、32.48條,為最適種蛭。

The number of 500 Whitmania pigras were chose as samples randomly. We made a statistical analy- sis on 4 traits of Whitmania pigras including body weight, cocoon weight, cocoon number, emergence rate by using SPSS 13 software package in the bivariate correlation analysis (Bivariate) program. By the correlation a- nalysising between Whitmania pigras body weight, cocoon weight, cocoon number and emergence percentage, we found that the correlation coefficients were 0. 8697, 0.9351and 0. 6972, respectively, showed a highly sig- nificant positive correlation. The correlation coefficient between the number of cocoon and egg cocoon weight was - 0. 563, showing highly significant negative correlation. At the same time, the correlation coefficient be- tween the egg cocoon weight and cocoon seedling number, the number of egg cocoon and cocoon seedling num- ber were 0.8172, 0.4873, respectively, both showing positively related. The average fecundity, average egg weight, average seedling number of 20-30 g Whitmania pigra which was the most suitable provenances were 2.78 individual, 2.24 g and 32.48g, respectively.
