【摘要】 选取2种新型LED植物光源(LED-Ⅰ、LED-Ⅱ),1种国产LED植物光源(LED-Ⅲ),1种进口LED植物光源(LED-Ⅳ)作为试验的4个处理,研究不同LED光源对千禧幼苗质量的影响。结果表明LED-Ⅰ、LED-Ⅳ照射下植株地上部分鲜重(干重)、全株干重、生长速率、壮苗指数、SOD、CAT表现均显著优于LED-Ⅱ、LED-Ⅲ。结论:LED-Ⅰ、LED-Ⅳ有利于‘千禧’幼苗培养。更多还原

【Abstract】 2 kinds of new LED plant light sources(LED-Ⅰ,LED-Ⅱ),1 kinds of domestic LED plant light sources(LED-Ⅲ),1 kinds of imported LED plant light sources( LED-ⅠV) were selected as the 4 treatments of the experiment, and the effects of different LED light sources on the quality of Millennium seedlings were studied. The results show that LED-1 and LED-ⅠV under the irradiation of the shoot fresh weight( dry weight),the whole plant dry weight, growth rate, seedling index, SOD and CAT were significantly better than those of LED-Ⅱ,LED-Ⅲ. Conclusion: LED-Ⅰ and LED-ⅠV are beneficial to the cultivation of millennial seedling stage.更多还原
