低氘水对水培生菜生长及品质的影响

Effects of Deuterium Depleted Water on Growth and Quality of Lettuce under Hydroponic Culture

[目的]低氘水对水培生菜生长及品质的影响。[方法]以"富兰德里"生菜为材料,在水培条件下,研究0.005%低氘水对生菜生长及营养品质的影响。[结果]与对照相比,0.005%低氘水培育的生菜比较矮小,叶片数和根长显著增加,明显降低亚硝酸盐的含量,同时总酚含量、总抗氧化能力与羟自由基清除能力显著提高。[结论]该研究可为低氘水在蔬菜生产上的应用提供理论依据。

[ Objective ] To research the cffects of deuterium depleted water on growth and quality of lettuce under hydroponic culture. [ Method ] With ＇ Flandria＇ lettuce as experimental materials, we researched the effects of 0.005% DDW on the growth and nutritional quality of lettuce under hydroponic culture. [ Result ] C ompared with the control,lettuce under 0.005% DDW treatment was dwarfed,and the number of leaves and roots increased significantly ,which significantly ledueed the nitrite content. At the same time, the total phenol content, total antioxidant capacity and hy- droxyl radical scavenging capacity significantly inmeased, compared with the control. [ Conclusion ] This research provided theoretical basis for the application of DDW water in vegetable production.
