菊花（Chrysanthemum morifolium Ramat.）是世界上最重要的切花之一。由于菊花是一种短日照（SD）植物，因此从秋季到春季通过白炽灯（INC）进行夜间休息（NB）处理对于切花的全年生产是必要的。INC灯是用于调节开花的有效光源，因为它发射波长范围从400 nm到超过800 nm的光。但作为防止全球变暖的措施，日本政府取消了INC灯的制造和销售。因此，开发新的光源来取代INC灯是对植物进行NB处理的迫切需要。荧光灯不仅容易损坏，而且不一定是菊花NB处理的最佳光源，因为它们不适合某些菊花品种，并且开花抑制不完全（Cathey和Borthwick，1970）。LED灯最近已经被开发出来，并且具有比INC灯更低的能量消耗和更长的耐用性的优点。LED灯在窄的波长范围内发光，并且对于光形态发生非常有效，特别是在低光强度下（Ohishi等人，2010年）。然而，很少有使用发光二极管在植物中进行NB治疗的情况（Arai和Ohishi，2010年）。光质和光周期调节植物生长和发育的许多方面，包括茎的伸长和开花。芽伸长受光波长影响;蓝光和远红光（FR）具有积极作用（Hirai等人，2006; Shimizu等人，2008; Arai和Ohishi，2010），而红光具有抑制作用（Reid等人，2002年）。光敏色素是植物重要的光感受器，能诱导光形态建成反应。它们的最大吸收光谱为668 nm和730 nm，并且两种形式（Pfr和Pr）分别响应于R光和FR光（Kelly和Lagarias，1985; Lagarias等人，1987年）。在这项研究中，我们研究了芽伸长在NB处理期间对不同光质的反应，以及不同LED波长与芽伸长之间的关系。
Chrysanthemum (Chrysanthemum morifolium Ramat.) is one of the most important cut flowers in the world. As chrysanthemum is a short-day (SD) plant, night-break (NB) treatment by incandescent (INC) lamps from autumn to spring is necessary for the year-round production of cut flowers. The INC lamp is an efficient light source for regulating flowering, because it emits light at wavelengths ranging from 400 nm to over 800 nm. However, as a measure to prevent global warming, the Japanese government canceled the manufacture and sale of INC lamps. Therefore, the development of new light sources to replace INC lamps is a pressing need for the NB treatment of chrysanthemums. Fluorescent lamps not only are easily damaged, but also are not necessarily the optimal light source for NB treatment in chrysanthemums, because they are unsuitable for some chrysanthemum varieties, and flowering inhibition is incomplete (Cathey and Borthwick, 1970). LED lamps have recently been developed, and have the advantages over INC lamps of lower energy consumption and longer durability. LED lamps emit light over a narrow range of wavelengths, and are highly effective for photomorphogenesis, particularly at low light intensities (Ohishi et al., 2010). However, there have been few instances where NB treatment in chrysanthemums has been conducted using LEDs (Arai and Ohishi, 2010). Light quality and photoperiod regulate many aspects of plant growth and development, including stem elongation and flowering. Shoot elongation is affected by light wavelength; blue and far-red (FR) light have a positive effect (Hirai et al., 2006; Shimizu et al., 2008; Arai and Ohishi, 2010), whereas red (R) light has an inhibitory effect (Reid et al., 2002). Phytochromes are important light sensors in plants, and induce photomorphogenic responses. Their maximum absorption spectra are 668 nm and 730 nm, and the two forms (Pfr and Pr) respond to R light and FR light, respectively (Kelly and Lagarias, 1985; Lagarias et al., 1987). In this study, we investigated shoot elongation responses to different light qualities during NB treatment in chrysanthemums, as well as the relationship between different LED wavelengths and shoot elongation.
