以番茄“白果强风”为试材,研究比较了玻璃日光温室自然光及LED光照下光合作用效率、可溶性糖含量、可溶性蛋白质含量和叶绿素含量等指标,以分析LED灯光对番茄生长和生理特性的影响。结果表明:较低LED光照下生长的番茄的净光合效率与日光温室栽培番茄相当,与自然光下的番茄植株相比较,LED光照下生长的番茄叶片的可溶性蛋白质、可溶性糖含量稍有降低,但LED光照下番茄叶片相对叶绿素含量明显提高。
Tomato “Ginkgo biloba ” was used to study the photosynthesis efficiency, soluble sugar content, soluble protein content and chlorophyll content under natural light and LED light in glass solar greenhouse to compare the effects of LED light on tomato growth and physiological characteristics Impact. The results showed that the net photosynthetic efficiency of tomato grown under lower LED illumination was similar to that of solar greenhouse cultivated tomato. Soluble protein and soluble sugar content of tomato leaves grown under LED illumination decreased slightly compared with that of tomato under natural light, The relative chlorophyll content of tomato leaves increased significantly under LED illumination.
