不同光质补光对番茄、黄瓜幼苗生长的影响
Effects of Different LED Supplemental Lighting on Growth of Tomato and Cucumber Seedlings
摘要
Abstract
The effects of light quality on the growth of tomato and cucumber seedlings were studied by different Light Emitting Diode ( LEDs) supplemental lighting ( red 630 ~660nm, orange 590 ~610nm, blue 450~460nm, green 520~540nm, 12 h, 120μmol·m-2·s-1). The results showed that, under the red and blue supplemental lighting treatment, leaf area, seedling index, concentration of photosynthetic pigment, fresh weight and dry weight of plant and shoot in tomato seedling were significantly higher than those of other treatments. Under the red and green supplemental lighting treatment, plant height and stem diameter of tomato seedling significantly increased. Under supplemental lighting treatments, the plant height significantly decreased while seedling index significantly increased in cucumber seedling, especially under red and blue lighting treatment. The chlorophyll concentrations in cucumber seedling decreased under red, orange and blue LED supplemental lighting.关键词
