摘要
为探明人工光源植物工厂中不同光质对油葵芽苗生长和芳香物质成分和含量的影响,在光强为200μmol/(m^(2)·s)的条件下,以蓝光LED为对照,在蓝光的基础上分别添加光强一致的绿光、红光、远红光和紫外线,研究不同光质组合处理下油葵芽苗的生长以及芳香物质等指标的变化。与对照相比,蓝光+远红光处理下的油葵芽苗下胚轴长显著增加,而蓝光+红光处理下的油葵芽苗的下胚轴直径、根长、全鲜和全干质量与对照相比均显著提高;不同光质处理对油葵芽苗的品质指标有不同程度的影响,蓝光+绿光处理下的油葵芽苗的可溶性糖、可溶性蛋白、类黄酮含量与对照蓝光相比显著上升,分别增加了28.78%,72.25%,163.32%。蓝光+紫外线处理下的总酚、维生素C、叶绿素a和类胡萝卜素含量较对照蓝光分别显著上升了25.81%,238.10%,12.50%,150.00%。蓝光+远红光处理有利于提高油葵芽苗特征挥发性芳香物质的含量,如青叶醛、α-蒎烯、对异丙基甲苯等,该处理下芳香物质的含量高于对照蓝光处理,且含量最大,使油葵芽苗菜具有清香。综上所述,蓝光+红光能促进油葵芽苗生长,蓝光+绿光则对油葵品质有较好的提升。
It was carried out to understand the effect of different light spectrum on the growth and quality of Helianthus annuus sprouts in artificial light plant factory.Green light(B+G),red light(B+R),far red light(B+Fr)and ultraviolet light(B+UV)with the same light intensity were added on the basis of blue light with the light intensity of 200μmol/(m^(2)·s).Blue LED was taken as the control.The results showed that the hypocotyl length of Helianthus annuus sprouts under B+Fr treatment increased significantly compared with the control.B+R treatment greatly improved the hypocotyl diameter,root length and fresh and dry weight of Helianthus annuus sprouts.Light quality treatments also affected the quality indexes of Helianthus annuus sprouts.Compared with the control,the content of soluble sugar,soluble protein and flavonoids of Helianthus annuus sprouts under B+G treatment increased significantly,increased by 28.78%,72.65%and 163.32%respectively.B+UV treatment significantly increased the content of total phenol,vitamin C,chlorophyll a and carotenoid by 25.81%,238.10%,12.50%and 150.00%,respectively.B+Fr treatment was beneficial to increase the content of volatile aromatic substances in Helianthus annuus sprouts,such as C_(6)H_(10)O,C 10 H_(16)and C_(10)H_(14).In conclusion,B+R promotes the growth of Helianthus annuus sprouts,while B+G light improves the quality of Helianthus annuus sprouts.
