| 摘 要： | 为了探究家蚕T6和734两品系耐氟力的差异，分别对其4龄时期氟敏指数，以及5龄时期体重变化和死亡率进行调查，在100ppm、200ppm、300ppm、400ppm氟化物浓度下．734的氟敏指数分别是：29．14、62．22、104．36和137．61，而T6的分别是：4．38、11．13、26．87和43．76，两品系的氟敏指数随着氟化物浓度的增大而增大，但734指数增加远远大于T6；734体重变化较T6明显。并且734的死亡率也远大于T6。表明了家蚕T6品系具有较强的耐氟能力。

| Abstract: | In order to understand the difference in fluorine tolerance between the silkworm (Bombyx mori) strains T6 and 734,the fluorine-sensitive index of the fourth instar larvae and body weight change and mortality of the fifth instar larvae were investigated. In fluoride treatments at 100,200,300 and 400 ppm,the fluorine-sensitive index was 29.14,62.22,104.36 and 137.61 for 734 and 4.38,11.13,26.87 and 43.76 for T6,respectively,thus indicating that.the fluorine-sensitive index of both strains increased with incre... |
