摘要:
本试验以主栽甘薯品种心香为材料，采用水培方式研究了不同光照度和光周期对薯芽菜品质的影响,以期筛选出生产薯芽菜的最优光照度和光周期，为商业化生产提供理论依据。光照度处理试验结果表明，随着光照度的增强，薯芽菜可溶性蛋白、类胡萝素含量升高，硝酸盐含量降低，叶色变绿，硬度变大、咀嚼性变差。在750 lx光照度下薯芽菜可溶性蛋白和类胡萝素含量比2 250 lx光照度下略低，但叶色比较鲜绿，其咀嚼性较好。光周期处理试验结果表明，不同光周期处理间薯芽菜类胡萝卜素的含量存在显著差异（P＜0.05），但其可溶性糖、可溶性蛋白、维生素C含量差异不显著(P>0.05)。12 h/d光周期条件下的可溶性蛋白、类胡萝卜素含量最高，硝态氮含量最低，但硬度、内聚性最大，咀嚼性最差。4 h/d光周期条件下，薯芽菜的硬度、咀嚼性最好。本试验条件下，750 lx光照度、4 h/d光周期培养的薯芽菜叶色鲜绿，具有鲜嫩的口感和较好的营养品质。
Abstract:
In this paper, the effects of different light intensity and photoperiod on the quality of sweetpotato sprouts were studied by using the main cultivar Xinxiang, in order to screen out the optimal light strength and photoperiod of sweetpotato sprouts and provide the theoretical basis for the commercialization of sweetpotato sprouts. The results of light intensity test showed that with the enhancement of light intensity, the content of soluble protein and carotenoids in sweetpotato sprouts increased, the nitrate content decreased. Meanwhile, the leaf color turned more green, the hardness became greater, and the chewiness became worse. The contents of soluble protein and carotenoids in sweet potato sprouts in 750 lx light intensity were lower than those in 2 250 lx light intensity, but the leaf color was slightly green and its chewiness was better. The results of different photoperiod treatment showed that there was significant difference in carotenoid content (P<0.05), but the contents of soluble sugar, soluble protein and vitamin C were not significantly different (P>0.05). The contents of soluble protein and carotenoid were the highest at 12 h/d, the content of nitrate nitrogen was the lowest, the hardness and cohesion were the highest, and the chewiness was the worst. The hardness and chewiness of sweetpotato sprouts were the best at 4 h/d. Under the conditions of this test, 750 lx light intensity and 4h/d photoperiod were selected, and the sweetpotato sprouts had fresh taste and good nutritional quality.
