摘要/Abstract

摘要： 以不同剂量T-2毒素染毒的凡纳滨对虾(Litopenaeus vannamei)为研究对象,以毒素染毒剂量为自变量、凡纳滨对虾形态学指标为因变量,采用灰色关联度分析、通径分析和回归分析探究毒素剂量与染毒凡纳滨对虾形态学指标的相关性,筛选出最便捷、最简单的生物学统计方法。灰色关联度和通径分析显示,凡纳滨对虾体质量、体长、头胸甲长和第一腹宽是受T-2毒素影响最大的指标;利用回归分析进行显著性检验发现,T-2毒素对凡纳滨对虾体质量、体长、头胸甲长和第一腹宽指标的影响均为显著水平(P<0.05)。3种统计学方法得出的结果相吻合,体质量、体长、头胸甲长、第一腹宽等染毒凡纳滨对虾形态指标的重要生物学标记,均与T-2毒素的暴露剂量呈负相关。其中,灰色关联度分析法是最便捷、最简单的生物统计法。

Abstract: Litopenaeus vannamei was adopted as the research object in this study, which was treated with different doses of T-2 toxin. T-2 toxin dose was adopted as the independent variable, along with morphological indicators of shrimp as the dependent variable. To investigate the correlation within the dose of T-2 toxin and various morphological indexes of treated shrimp, common statistical analysis methods were used including gray correlation analysis method, path analysis and regression analysis. The most convenient and simple biological statistics were filtered out. The experimental results indicated that the body weight, body length, carapace length and the first abdominal segment width of toxic shrimp morphological index were the most influential indexes of T-2 toxin as analyzed by gray correlation and path analysis. The significance test performed by regression analysis showed that the effects of T-2 toxin on body weight, body length, carapace length and the first abdominal segment width of treated shrimp were significant (P<0.05). The results of the three statistical methods were consistent. Body weight, body length, carapace length and the first abdominal segment width were the important morphological indicators of toxic shrimp, and they were negatively correlated with the exposure dose of T-2 toxin. And gray correlation analysis was the most convenient and easiest biological statistics.
