摘要：
以决明(Cassia tora L.)幼苗为材料,采用半导体发光二极管光源(LED)精确调制白光(W)、红光(R)、蓝光(B)、绿光(G),对决明(C.tora)芽苗进行2 h的辐照处理,探究对决明(C.tora)芽苗菜光合色素、可溶性糖、可溶性蛋白、总酚、类黄酮及花青素含量的影响.结果表明:以室内自然光处理(D)为对照,各光质都显著提高决明(C.tora)芽苗菜中叶绿素及类胡萝卜素的含量,绿光处理叶绿素a含量增加了31.73%,白光处理叶绿素b以及叶绿素总含量、类胡萝卜素含量分别增加了50.20%、33.62%、52.71%;红光处理可溶性糖含量增加了57.04%;蓝光、白光和红光处理可溶性蛋白含量分别增加了69.33%、51.74%、40.58%;几种光质处理后总酚和类黄酮含量都明显高于对照组,但不同光质间差异不明显;蓝光处理花青素含量最高,增加了32.89%.生产中可通过增加LED照射提高决明(C.tora)芽苗菜的营养品质.
The effects of LED light qulities on photosynthetic pigments, soluble sugar, soluble protein, total phenols, fla- vonoids and anthocyanins content of Cassia torah. seedlings were investigated with treatments of 2h. C. tora sprouts were dis-posed in white light（W） , red light（R） , blue light（B） , green light（G） generated by light-emitting diode applied. The results showed that in comparison with those of the indoor natural light treatment, the chlorophyll and carotenoid contents of all the different light both increased extremely significantly. The chlorophyll a contents of green light increased by 31. 73 % ; the chlo-rophyll b, the sum of chlorophyll a and b, and the carotenoid contents of white light increased by 50. 20% , 33. 62% , 52. 71% respectively; the soluble sugar contents of red light increasedby 57. 04%; the soluble protein contents of blue light, white light, red light increased by 69. 33% , 51. 74% , 40. 58% respectively; and for the total phenolsand flavonoidscontents of all the different light qulities both increased extremely significantly, but there are no obvious difference between the different light qualities. The anthocyaninscontents of blue light increased highest by 32. 89%. Production can be increased C. tora sprouts nu-tritional quality by increasing the LED illumination.
