Effects of Ultraviolet Rays on Phenotype Variation and Development of Drosophila melanogaster
摘要/Abstract
对紫外线照射黄身果蝇进行了研究.结果表明:紫外线照射能够极显著地降低果蝇的寿命,使果蝇成蝇的存活时间比对照组降低66.31%~83.96%;能够抑制果蝇的产卵量,并降低卵的成活率;影响子代的个体发育,使子二代个体重量减少12.08%.紫外线照射还能影响当代或子代的行为性状,引起果蝇子代的表型变化.随着照射时间的延长和照射频率的增加,其伤害作用明显增加.
The yellow Drosophila melanogaster were irradiated by ultraviolet rays. The result showed that the life-span was reduced notably, and there was 66. 31 % ~ 83. 96 % decreased than that in the control group. Otherwise, the number of eggs, the survival ratio of eggs are also reduced. Even the growth and development of Drosophila melanogaster were influenced, the weights of second filial generation were observed 12. 08 % lower than those in the control group. After the ultraviolet irradiation, the behavior and character of the first generation and the second generation were influenced, the phenotypes of the secondg eneration were changed. The injury was more obviously increased as the time of radiation was extended and the frequency of irradiation was increased.
