中文摘要：

以荧光灯为对照,采用LED调制光质和光量,研究不同光质对萝卜芽苗菜生长和营养品质的影响。结果表明,红光处理对萝卜芽苗菜生长影响显著,下胚轴长、子叶面积、植株鲜质量及干质量均达到最大值,且显著高于对照。红光与红蓝光组合处理下,可溶性糖与淀粉含量均显著高于对照。综合考虑认为应用红光照射有利于萝卜芽苗菜生长,提高产量,改善部分营养品质。

英文摘要：

Effects of different spectra of light emitting diode （LED） on growth of radish sprouting seedlings were studied. Light generated from LED and fluorescent lights were used as the control. From the experimental results, red LED was the most effective for the growth of radish sprouting seedlings, and exhibited the highest hypocotyl length, cotyledon area, fresh weight and dry weight. Red LED, combination of red and blue LED significantly increased the contents of soluble sugar and starch. The results suggested that application of red LED could accelerate the growth of radish sprouting seedlings, increase yield and improve partial nutrient quality.
