Abstract:
Taking lettuce as test materials,included green leaf，red leaf，purple leaf and dark purple leaf lettuce.As the control of fluorescent lamp (FL)，two kinds of LED composite light quality，red light∶blue light=4∶1 (RB) and red light∶blue light=20∶5∶1 (RBU) with the same power were used as the light treatment for the four potted lettuces with different leaf colors.The effects of different light quality treatments on the growth，yield and quality of different varieties of lettuce were compared，in order to explore the effects of ultraviolet-B (UV-B) irradiation on the production of different lettuce cultivars.The results showed that the performance of the four varieties of lettuce was the worst under fluorescent lamp treatment.The stem diameter and aboveground fresh weight of green leaf lettuce under RBU treatment were significantly lower than those under RB treatment，but the vitamin C content of green leaf lettuce under RBU treatment was significantly higher than that under RB treatment.There were no significant differences in the growth indexes and biomass of purple leaf and dark purple leaf lettuce under RBU treatment and RB treatment，however，the anthocyanin content of RBU treatment was significantly higher than RB treatment.
