弱光条件下光质与连续光照对水培生菜生长与品质的影响
Influence of Light Quality and Continuous Lighting on Growth and Nutritional Quality of Two Two-color Lettuce Cultivars
摘要
Abstract
Purple lettuce and green lettuce were hydroponically cultivated in a culture room to investigate the influence of light quality and continuous lighting on their growth and nutritional quality.The results showed that the shoot fresh weight and root fresh weight of the two kinds of lettuce improved under treatment of continuous lighting.The shoot fresh weight of purple lettuce under RB 2∶1 treatment was significantly higher than that of RB 1∶2 when the photoperiod was the same, but that of green lettuce didn’ t showed significant difference.Phenol and flavonoid relative contents of purple lettuce and green lettuce responded to continuous lighting treatment differently with the variation of light quality.When under the same lighting period, phenol and flavonoid relative contents of purple lettuce and green lettuce reduced with the increasing of red light ratio.The ascorbic acid content of purple lettuce lessened greatly under continuous lighting.The soluble sugar and soluble protein contents of purple lettuce didn’ t change much with the variation of red and blue light ratio and lighting period.The influence of continuous lighting on soluble sugar content of green lettuce differed with the change of light quality.When under the same light quality, soluble protein contents of green lettuce dropped under treatment of continuous lighting.And soluble sugar and soluble protein contents of green lettuce responded differently to the change of light quality with the alteration of lighting period.关键词
