| 摘 要： | 以黑体红眼长翅果蝇(Drosophila melanogaster)为材料,培养基用硝酸镍和氯化汞染毒(浓度为0.5μg/mL、5μ/mL、15μg/mL、30μg/mL)后对果蝇后代的雌雄性比、存活率,体重的影响进行研究.结果表明:随着镍、汞浓度的增加和处理世代的增加,Ni2+对果蝇雌雄性比、存活率和体重的毒害较Hg2+轻;高浓度的Hg2+严重抑制雄果蝇的发育;降低果蝇的存活率,抑制果蝇体重的增加.这表明Hg2+对果蝇的毒害要比Ni2+重.

| Abstract: | Drosophila melanogasters were cultured in the media with the different concentrations of nickelous nitrate and the mercuric chloride(0.5μg/mL,5μ/mL,15μg/mL,30μg/mL).The effect of nickelous nitrate and the mercuric chloride on its Male-female sex ratio of adults insect,survival rate of adult insect,the weight of adult insect.The results showed that with nickel,mercury concentration and generation of extended treatment,nickel ions on the Drosophila male and female sex ratio,survival rate and weight were less than mercury ions;High concentrations of mercury ions significantly reduce the development of male Drosophila melanogaster,reduce the survival rate of Drosophila,and restrain weight gain of Drosophila;Mercury ions cause severer injury on Drosophila,compared with nickel ions. |
