Title: Effects of LED Light Quality on Growth Vitality,Photosynthetic Performance and Antioxidant Enzymatic Activity of Tomato Seedlings
Abstract: Taking ‘Hezuo 903' tomato as material,light emitting diode(LED)was applied to accurately modulate the composition of light quality,the effects of supplemental light quality on the growth,photosynthesis and antioxidant enzyme in tomato seedlings were studied,in order to provide a theoretic reference for the commercial production of this seedling.The results showed that compared with the under monochromatic light,mixed light of red and blue obviously increased leaf area,fresh and dry weight,strong seedling index and net photosynthetic rate.Of them,the mixed light with red∶blue 2∶1(R/B 2∶1)was the best to improve leaf area,fresh and dry weight,soluble sugars and soluble proteins,CAT activity,strong seedling index,root activity and net photosynthetic rate.Supplemental light R/B 2∶1 could be used in future industrialized breeding of this species owing to its function to promote seedling productivity.
