Abstract：In order to investigate the effects of LED light formulations in seedlings raising on the growth,yield and quality of cherry tomato,the tomato cultivar Yuekeda 205 was used as the test material,and four light formulations were set up here,including T1(white light),T2(the red/blue light with the ratio 3∶1),T3(the red/blue light with the ratio 1∶1),T4(the red/blue light with the ratio 1∶3)[photosynthetic photon flux density(PPFD)=200 µmol/(m2·s)],and T5(natural light)was used as the control group[PPFD=500-600µmol/(m2·s)].The results showed that LED light formulations supplied in seedlings raising could significantly increase the plant height,stem diameter,leaf number,total dry mass and seedling strength index of cherry tomato seedlings,which was more beneficial to cultivate strong seedlings as compared with T5 treatment.In addition,different LED light formulations supplied in seedlings raising significantly increased the number of flowers and fruit set of cherry tomato.Compared with T5,T2 not only significantly increased the total number of flowers and fruit set in plants,but also improved the content of phosphorus and fruit fresh mass per plant.Meanwhile,through principal component analysis,T2 was found to rank first in comprehensive score,indicating the best comprehensive effect on cherry tomatoes.Therefore,proper LED light formulation supplied in the seedling raising is an effective strategy to promote the cultivation of strong seedlings and ensure fruit yield of cherry tomato without compromising fruit quality.
