以菊花品种‘Arajin2’和‘Iwanohakusen’为材料，研究了不同夜间光照波长对菊花花芽分化的抑制作用。波长为516、593,630、663,684和705 nm的光由LED灯产生。‘Arajin2’和‘Iwanohakusen’的有效抑制波长分别为593、630和663 nm，其中‘Arajin2’和‘Iwanohakusen’的有效抑制波长分别为630 nm和593和630 nm。使用“Arajin2”和“Iwanohakusen”比较了红光或红光和远红光混合光作为夜间照明的有效性。对‘Arajin2’花芽分化的抑制效果无显著差异，而红光和远红光混合光对‘Iwanohakusen’花芽分化的抑制效果优于红光。
Effects of the wavelength of night-break light on the inhibition of flower bud differentiation in chrysanthemum were investi-gated using the cultivars ‘Arajin2’ and ‘Iwanohakusen’. Wavelengths of 516, 593, 630, 663, 684, and 705 nm of light were produced using LED lamps. Effective wavelengths for inhibition in both ‘Arajin2’ and ‘Iwanohakusen’ were 593, 630, and 663 nm, and the most effective wavelength was 630 nm in ‘Arajin2’ and 593 and 630 nm in ‘Iwanohakusen’, respectively. The effectiveness of red light or a mixture of red and far-red light as a night-break light was compared using ‘Arajin2’ and ‘Iwanohakusen’. No difference in the inhibition of flower bud differentiation was observed in ‘Arajin2’, whereas the mixed light of red light and far-red light was more effective than red light to inhibit flower bud differentiation of ‘Iwanohakusen’.
