不同短日照对不同叶龄谷子生长发育的影响

Effects of Different Leaf Age and Short-day on Growth and Development of Foxtail Millet

谷子是短日照作物,短日照处理可以减少单株叶片数,促进出叶速度,从而提前抽穗,缩短育种进程。谷子在五叶期时,给予8h短日照光周期处理效果最显著。

Foxtail Millet is short-day crop. The treatment of short-day could reduce theleaf number of single plant and accelerate the speed of leaf development. and the pre-head-ing of foxtail millet. The breeding procedures. of foxtail millet could be reduced. The treat-ment of short-day under 8 hours was the most significant at the five-leaf stage of foxtailmillet.
