Abstract:
Taking tomato seedlings as test materials,effects of different LED light quality on growth of tomato was studied in order to provide theoretic references for the commercial production of seedlings.Different LED light quality (red light,blue light,red/blue 7∶1 light and red/blue 2∶1 light) were used as light resources,with fluorescent light as control.Effects of different LED light quality on growth and physiological characteristics and photosynthetic characteristics of tomato seedlings were studied in order to provide references for the commercial production of seedlings.The results showed that compared with control,the different LED light quality treatments affected the growth and photosynthetic characteristics of tomato seedlings significantly in different ways.Compared with the under monochrome,could benefit the growth of the vegetable seedlings.Combinations of light (7R/1B) increased the leaf area,plant height,dry weight,seeding index,root activity and photosynthetic rate.It is concluded that the combinations of light (7R/1B) accelerate the growth of tomato seedling.
