以发光二极管(LED)精量调制光质(红光、蓝光和红蓝混合光),以白光(普通日光灯)为对照,研究红蓝光质对香椿芽苗菜营养品质(氨基酸、维生素 C、硝酸盐、粗纤维、总黄酮、单宁)的影响。结果表明:与白光相比,蓝光和红蓝光处理显著提高了香椿芽苗菜氨基酸含量,而红光处理降低了香椿芽苗菜氨基酸含量;3种光质均有利于香椿芽苗菜维生素 C 的形成和累积,其促进作用大小依次为蓝光>红光>红蓝混合光;各处理均抑制香椿芽苗菜硝酸盐的累积,其中红光的抑制作用最强;红光处理可提高香椿芽苗菜的粗纤维含量,而蓝光处理则降低香椿芽苗菜粗纤维含量;与对照相比,蓝光和红蓝混合光处理提高了香椿芽苗菜总黄酮的含量,同时降低了香椿芽苗菜单宁的含量。总之,蓝光和红蓝混合光处理可提高氨基酸、维生素 C、总黄酮含量,同时可降低硝酸盐、粗纤维和单宁含量。因此,蓝光和红蓝混合光处理更有利于提高香椿芽苗菜品质。
以髮光二極管(LED)精量調製光質(紅光、藍光和紅藍混閤光),以白光(普通日光燈)為對照,研究紅藍光質對香椿芽苗菜營養品質(氨基痠、維生素 C、硝痠鹽、粗纖維、總黃酮、單寧)的影響。結果錶明:與白光相比,藍光和紅藍光處理顯著提高瞭香椿芽苗菜氨基痠含量,而紅光處理降低瞭香椿芽苗菜氨基痠含量;3種光質均有利于香椿芽苗菜維生素 C 的形成和纍積,其促進作用大小依次為藍光>紅光>紅藍混閤光;各處理均抑製香椿芽苗菜硝痠鹽的纍積,其中紅光的抑製作用最彊;紅光處理可提高香椿芽苗菜的粗纖維含量,而藍光處理則降低香椿芽苗菜粗纖維含量;與對照相比,藍光和紅藍混閤光處理提高瞭香椿芽苗菜總黃酮的含量,同時降低瞭香椿芽苗菜單寧的含量。總之,藍光和紅藍混閤光處理可提高氨基痠、維生素 C、總黃酮含量,同時可降低硝痠鹽、粗纖維和單寧含量。因此,藍光和紅藍混閤光處理更有利于提高香椿芽苗菜品質。

Red light(RL),blue light(BL),red + blue light(R/ BL)generated by light ̄emitting diode were applied,and white light(WL)generated by fluorescent lamps was used as control. The authors studied the effects of different light qualities on nutritional quality ( amino acids, Vc, nitrate, crude fiber, total flavonoid and tannin) of Toona sinensis sprouts. The results showed that the treatments of BL and R/ BL increased significantly amino acid content of Toona sinensis seedlings compared with the white light treatment,while the RL had the opposite effect. The three spectral quality treatments had the superiority in promoting synthesis and accumulation of Vc in Toona sinensis seedlings, the increase in turn were BL > RL > R/ BL. The three treatments of light quality inhibited the accumulation on nitrate of Toona sinensis seedlings, and the strongest inhibition was RL treatment. The crude fiber content of Toona sinensis seedlings was raised under RL,but reduced under BL. Compared with the control,BL and R/ BL treatments increased the total flavonoid content of Toona sinensis seedlings,while also reduced the content of tannin. To summarize,BL and R/ BL treatments could raise amino acids,Vc and total flavonoid of Toona sinensis seedlings,and could reduce the content of nitrate,crude fiber and tannin at the same time. Therefore,BL and R/ BL light could promote nutritional quality of Toona sinensis seedlings.
