The developmental time of period mutants in Drosophila melanogaster was monitored under different environmental conditions. We observed that the pers mutants, which have short 19 h circadian cycles, develop faster from eggs to adult than the wild-type: perL mutants, which have long 28 h circadian rhythms, complete development more slowly than the wild-type. These results suggest that endogenous timers may be involved in regulating the development time of D. melanogaster.
在不同环境条件下监测了黑腹果蝇周期突变体的发育时间。我们观察到，具有19小时短昼夜节律周期的pers突变体从卵发育到成虫的速度比野生型快；而具有28小时长昼夜节律的perL突变体完成发育的速度比野生型慢。这些结果表明，内源性计时器可能参与调节黑腹果蝇的发育时间。
