摘　　要：采用6种LED光源进行培养,以荧光灯为对照,研究不同光质对构树组织培养苗鲜质量、干质量和蛋白质、全磷、全钾含量的影响。探究不同LED光质对构树组织培养苗生长量和营养物质含量的影响,为构树组织培养光环境的改善提供理论依据。结果表明:与荧光灯相比,LED光质处理能显著提高幼苗的干物率(P<0.05),蓝光和绿光处理下幼苗干物率最高,荧光灯、紫光、红光处理下幼苗干物率较低,含水量较高;LED光质培养下幼苗的蛋白质、全磷和全钾的含量均显著高于荧光灯(P<0.05),通过模糊隶属函数法分析,紫光和绿光处理下幼苗营养物质含量综合排名最高。To explore the effect of LED light on the growth of Broussonetia papyrifera tissue culture,compared with fluorescent lamps,the fresh weight,dry weight and proteins,total phosphorus and total potassium content of tissue cultured plantlets were studied under different LED lights.The results showed that the appropriate LED light was better than fluorescent lamps in the dry matter rate of tissue cultured plantlets,that was,blue light and green light were the best,but the dry matter accumulation of plants was lower and water content was higher under fluorescent lamps,purple light and red light.The content of proteins,total phosphorus and total potassium of plants under all LED lights were significantly higher than that under fluorescent light(P<0.05).Through the analysis of fuzzy subordinate function value,the nutrient content of plants under purple light and green light were the highest.
