Abstract:
Tomato seedlings cv. ‘Jinpeng chaoguan’ were used as experimental material, matrix cultivation method was adopted and 1/2 times Yamasaki tomato nutrient solution was used to provide nutrition for the seedlings. LED was used as light resources, under 200 μmol m-2 s-1 light intensity, with white light (W) as control, and in order to select the most suitable light quality ratio for the growth of tomato seedling, the effects of different red and blue light ratios(R:B=1:0,2:1,1:1,1:2,0:1) on tomato seedlings were studied.The results showed that, plants height and stem diameter of seedlings under R treatment significantly were higher than those under other treatments, and plants height under B treatment was lowest. After 25 days under different light quality treatments, Pn of seedlings under W was highest, followed by 2R1B, and it had lowest under B treatment. Moreover, Gs under 1R2B was highest, while it was lowest under R. The Chl a/b was found under 1R1B was highest, and the surface area of seedlings roots was highest under 2R1B whereas the root volume under 1R1B reached the highest point. Moreover, the healthy index under 2R1B and1R1B significantly higher than those under other treatments. In conclusion, R treatment results in seedlings spindling while B treatment suppress its growth. Seedlings had discrepant responsive under different light quality and the roots volume was highest under 1R1B, and 2R1B and 1R1B were most suitable red and blue light ratios for tomato seedlings growth.
