摘　　要：以银条组培苗为材料,研究了不同LED光源对组培苗生长的影响。结果表明:蓝色光下银条组培苗不定芽长势最好,叶片大而展开;绿色光不定芽下增殖倍数最高,达到317%;白色光和对照光源下叶绿素含量最高,蓝光下次之,黄光下叶绿素a+b仅为白光的37%,最少;类胡萝卜素含量趋势和叶绿素含量相近;总酚含量由低到高依次为绿色光、黄色光、白色光、红色光、蓝色光和对照。Taking tissue culture seedling of Stachys floridana Schuttl.ex Benth as material,the effect of different light emitting diode on growth of adventitious bud were studied.The results showed that the growth vigor of the adventitious bud under blue light source was the best,and its leaf was large and exhibition.The increment multiple of the adventitious bud under green light source was the highest,reached 317%.The content of chlorophyll of the tissue culture seedling under white and control light source were the highest,the content of chlorophyll of the tissue culture seedling under blue light source was the second,the content of chlorophyll a＋b under yellow light source was only 37%for the white light source.The trend of content of carotenoid of the tissue culture seedling was similar to the chlorophyll.The content of total phenols ranged that under green light source〈under yellow light source〈under white light source〈under red light source〈under blue and control light source.
