中文摘要 | 根据传统形态度量学和框架结构形态学法测量了15月龄的杂交F1代(滇池金线鲃Sinocyclocheilus grahami♀×西畴金线鲃S.xichouensis♂)以及滇池金线鲃(S.grahami)和西畴金线鲃(S.xichouensis)的10项传统可量性状数据和24项框架结构数据以及鳍条、侧线鳞和脊椎骨等可数性状数据。并用方差分析和多元统计分析法(聚类分析,判别分析和主成分分析)对三者的传统可量性状和框架结构数据进行分析。结果显示:三者的可数性状差别不大,杂交F1代体表花纹与双亲相比发生一定变化。聚类分析结果表明,杂交F1代的形态与母本滇池金线鲃形态较为相似。采用逐步判别分析方法建立了3种鱼的判别函数,判别准确率较高(90%,90%,100%)。主成分分析结果及主成分散点图显示:三者均有重叠区域不容易从形态上清楚分开,但杂交F1代明显更接近母本滇池金线鲃。结合方差分析和主成份分析发现杂交F1代与双亲不同的性状主要集中在头部和尾部。 |
英文摘要 | Sinocyclocheilus grahami,S. xichouensis and their hybrid F1( S. grahami ♀ × S. xichouensis ♂) were infected twice by Ichthyophthirius multifiliis and Trichodina spp. artificially to conduct a investigation of their resistibility. The mean mortality rate of one and half a year' s hybrid F1,S. grahami and S. xichouensis which infected by I. multifiliis was( 50. 00 ± 11) %,( 56. 70 ± 23) %,( 80. 0 ± 18) % respectively. The mortality rate of hybrid F1 was significantly lower than that of S. xichouensis by analysis of variance( P〈0. 05),it showed that the resistibility of hybrid F1 was obviously higher than its male parent. The mean mortality rate of half of a year's hybrid F1,S. grahami and S. xichouensis which infected by Trichodina spp. was( 40. 56 ± 13) %,( 56. 11 ± 05) %,( 42. 78 ± 13) % respectively. As a result of analysis of variance,mortality rate of hybrid F1 was significantly lower than that of S. grahami,it showed that resistibility of hybrid F1 was higher than its female parent apparently. Hybrid F1,S. grahami and S. xichouensis showed the similar tendency in mortality,it rose significantly in the first 3 days and reached the top during the 4thto 7thday,and then had a gradual fall,finally it dropped to 0. Trichodina spp. which was used to infect fish in this experiment appear mainly on skin of body surface: there are about 57% - 79% on trunk,12% - 28% on fins and fewer on head 4% - 15%. There are 10% - 20%I. multifiliis which was found on gills,different with I. multifiliis there are rarely Trichodina spp. be found on gills in this research 0% - 3%. |
