Effects of Light Quality and Photoperiod on Growth and Total Phenolics Content of Soybean Sprouts
摘要
Abstract
Light emitting diode(LED)was applied to accurately modulate light spectral energy distribution. The effects of light quality and photoperiod on the growth,total phenolics content and DPPH scavenging activity of soybean(Glycine max)sprouts were studied.The results of light quality test indicated that hypocotyl length and edible rate were significantly decreased by UV-B,which was favorable for water accumulation in plant.Every light treatment significantly increased the content of total phenolics in hypocotyls.The total phenolics content reached the max under UV-B treatment,and was much higher than that in the darkness and other light treatment. Under UV-B treatment,the DPPH scavenging activity in hypocotyls and cotyledon of soybean sprouts reached the max,and was significantly higher than that of the darkness.The photoperiod test showed that the root length reached the max and the hypocotyl length reached the min when the photoperiod was 8 h·d-1 under UV-B.The total phenolics content and DPPH scavenging activity were significantly decreased by 8 h·d-1,12 h·d-1 UV-B treatment,and were much higher than that in the darkness and other light treatment.Overall,8 h·d-1 UV-B treatment was more beneficial for the the total phenolics content and the DPPH scavenging activity of soybean sprouts.关键词
