The active regulation of the plant growth environment is a common method for optimizing yield and quality. In horticulture today, light quality control carried out using photo-selective nets or membranes to improve cultivated plants. present study, with natural as (CK), we tested different (white, WN; blue, BN; green, GN; yellow, YN; red, RN) 30% shade characteristics growth, development, quality, yield, photosynthesis, chlorophyll fluorescence, considering antioxidant system, well influence element absorption transformation green onion ( Allium fistulosum L.) plants at stages. We found that under BN WN have greater height fresh weight than those other nets. Plants treatment had highest photosynthetic pigment content, net rate, transpiration stomatal conductance, whereas intercellular CO 2 concentration was in YN treatment. photosynthesis noon break phenomenon significantly lower covered CK NPQ treatment, Fv/Fm, ΦPSII, qP among treatments were different; from lowest, they follows: > RN GN YN. oxygen content leaves treatments, their key enzyme activity increased. also improved elements various organs onion.
