近紫外线，特别是UV-A，辐射的紫外线灯对萝卜植物的生长和生理活性的影响进行了研究，种植植物在塑料框架覆盖的聚氯乙烯薄膜，是不透明的太阳紫外线辐射在地球表面上。UV-A辐射促进了萝卜的生长，且这种促进作用与叶绿素含量和光合活性的增加有关。此外，硝酸还原酶活性，可溶性蛋白质水平，维生素C水平（抗坏血酸+脱氢抗坏血酸）和烟酰胺辅酶（NAD（H）和NADP（H））的水平在叶和所谓的地球仪“根”，其中包括萝卜植物的茎组织，也被UV-A辐射的提高。综上所述，这些数据表明，促进植物生长的UV-A辐射涉及促进碳和氮代谢的萝卜植物。
Effects of near-UV, especially UV-A, irradiation from UV lamps on the growth and physiological activity of radish plants were investigated by growing plants in plastic frames covered with a poly(vinyl chloride) film that was opaque to solar UV radiation on the Earth's surface. The growth of radish plants was promoted by the UV-A radiation, and the promotion by UV-A radiation was associated with an increase in chlorophyll content and photosynthetic activities. Furthermore, nitrate reductase activities, levels of soluble protein, levels of vitamin C (ascorbic acid + dehydroascorbic acid) and levels of nicotinamide coenzymes (NAD(H) and NADP(H)) in leaves and in the so-called globe “root”, which includes stem tissue in radish plants, were also elevated by UV-A radiation. Taken together, these data suggest that promotion of plant growth by UV-A radiation involves the promotion of carbon and nitrogen metabolism in radish plants.
