NaCl对果蝇生长发育的影响

目的]探索最适的食用NaCl浓度，为合理健康膳食提供科学依据。方法]以野生型黑腹果蝇为材料，在含有不同浓度NaCl（0、10、50、100、200mmol／L）的培养基上培养果蝇，分析NaCl对果蝇幼虫生长发育、子代果蝇数目、成虫体重、群体的雌雄平衡等所产生的影响。结果]含低浓度NaCl（10mmol／L）组子代蛹化数目和子代羽化数目有所增加；而高浓度NaCl组（100、200mmol／L）子代蛹化数目和子代羽化数目明显减少。不同浓度NaCl对子代果蝇体重的影响并不明显，但是随着NaCl浓度的提高，雄蝇体重和雌蝇体重都有减轻的趋势。结论]一定量的NaCl能够影响果蝇生长发育、子代数量，干扰果蝇群体的雌雄平衡，影响子代果蝇体重。

Effect of NaCl on the Growth and Development of Drosophila melanogaster

Objective] The reasonable basis of health food was provided through the experiment in the optimal concentration of NaCl in food.Method] The D.melanogasterunder were cultured in the media with the different concentrations of NaCl(0,10,50,100 and 200 mmol/L) and the effect of NaCl on its growth and development,the number of its offspring,the weight of adult insect,the balance of male to female insect was analyzed.Results] The results showed that the number of its offspring,the number of pupal and eclosion ...
