- 摘要:
- 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。
- Abstract:
- Taking tomato species ‘Baiguoqiangfeng’ as research materials,the effect of LED illumination on tomato growth and physiological characters were analyzed,the photosynthetic efficiency,soluble sugar content,relative chlorophyll content and protein content of the tomato plants were compared.The results showed that net photosynthetic rate of tomato plants cultured under lower light intensity of LED illumination was roughly equal to that of tomato plants cultured in greenhouse.The leaf protein,soluble sugar content of tomato plants under LED illumination was lower than that of tomato plants under natural light slightly.But the relative chlorophyll content of tomato leaf cultured under LED illumination was much higher than that of tomato plants cultured under natural light in greenhouse.
