夜歇效应在菊花生产中被广泛应用，通过应用白炽灯（INC）来抑制菊花开花，以获得更长的芽。为了节约能源，LED灯已被开发为一种新的光源，并用于农业。由于目前对LED光培养菊花的研究还很有限，我们通过使用几种不同波长的LED灯来研究菊花的夜间休息效果。LED-630和LED-660的红光对‘神巴’的花芽分化有很好的抑制作用，但对‘岩野’的花芽分化没有抑制作用。LED-735的远红光对‘神巴’的花芽分化没有抑制作用，但对‘岩野’的花芽分化有延迟作用。LED-690和INC灯处理抑制‘神巴’的花芽分化，并强烈延迟‘岩之白仙’的花芽分化。LED-660的R光和LED-735的FR光组合处理抑制了两个品种的花芽分化。
Night break effect is widely used in chrysanthemum production by applying incandescent (INC) lamps to inhibit flowering of chrysanthemum in order to obtain longer shoots. To save energy, LED lamps had been developed as a new light source and used in agriculture. Since there is limited research on chrysanthenwms grown in LED light culture, we studied the night break effect by using several different wavelengths of LED lamps. Red (R) light from LED-630 and LED-660 had perfect inhibition on floral bud differentiation in `Jimba,' but could not inhibit that in `Iwa no halcusen' chrysanthemums. The far-red (FR) light of LED-735 had no effect on the inhibition of floral bud differentiation in `Jimba; but it was delayed in `Iwa no halcusen.' Treatments of LED-690 and INC lamps inhibited floral bud differentiation in `Jimba' and strongly delayed that in `Iwa no hakusen.' Treatments of a combination of R light of LED-660 and FR light of LED-735 inhibited floral bud differentiation in both the cultivars.
