摘　　要：以豌豆为试验材料,设8红1蓝(8R1B、T1)、6红3蓝(6R3B、T2)、6红2绿1蓝(6R2G1B、T3)3个处理,以普通白光LED灯为对照(CK),研究不同光质LED植物灯对豌豆芽苗生长、光合色素(叶绿素a、b和类胡萝卜素)含量与营养品质(硝酸盐、维生素C、可溶性糖、可溶性蛋白、可溶性总酚、类黄酮和游离氨基酸)含量的影响。结果表明:与CK相比,3个处理均不同程度促进豌豆芽苗生长,其中以T3处理效果最好,下胚轴长增加27.50%,鲜重增加28.02%,干重增加33.85%。各处理的硝酸盐含量T1>T3>CK>T2,均低于国家规定的硝酸盐含量标准;3个处理的豌豆芽苗Vc和类胡萝卜素含量均显著高于CK;T3处理可增加可溶性蛋白、类黄酮的含量。综合得出:与CK相比,3个处理均可增加豌豆芽苗菜的产量,改善营养品质,其中T3处理效果最突出。The effects of different light-emitting diodes （LEDs） light quality （white （CK）, 8R1B（T1）, 6R3B（T2） and 6R2G1B （T3）） on the growth and quality of pea sprouts were studied.. The results showed that, compared to CK, the growth of pea sprouts were improved in 3 treatments and the best treatment is T3. The fresh weight and dry weight of sprouts in T3 treatment increased by 28.02%, 33.85%, respectively, and the hypocotyl length of sprouts in T3 increased by 27.50%. Nitrate contents of sprouts in these treatments were as follow ： T1〉T3〉CK〉T2 and far below the standard limit of nitrate in vegetables in China. The contents of vitamin C and carotenoid of sprouts in 3 treatments were significantly higher than CK. The contents of soluble protein and flavonoid increased in T3 treatment. In general, compared to CK, 3 treatments could increase the yield and improve the quality of pea sprouts, and T3 was the best treatment.
