光质是影响植物生长发育的重要光环境要素之一.为探究LED光质对青花菜生长和营养品质的影响,以青花菜‘湘绿3号’为试料,设置了红光（R）、蓝光（B）、红蓝光3:1（3RB）、绿光（G）、紫光（P）5种光质处理,并以白光（W）为对照,测定分析了青花菜的生物量、产量以及花球中硫苷、萝卜硫素、维生素C、总酚、原花青素、类黄酮含量和黑芥子酶活性.结果显示,与对照相比,红光、蓝光、红蓝光3:1和绿光处理对青花菜的生物量和产量均未造成显著影响（P> 0.05）,紫光处理下生物量显著降低（P

To explore the effect of LED light quality on the growth and nutritional quality of broccoli, five light quality treatments (red, blue, red + blue, green, and purple light) were set up in this study with white light as the control. The broccoli Xianglv 3 was used as the experimental material. The biomass, yield, glucosinolates, sulforaphane, vitamin C, total phenol proanthocyanidins, and myrosinase activity of broccoli were measured. The results showed that the biomass and yield of broccoli under red, blue, red + blue, and green light treatment...
