Abstract:
Thick-skinned melon used as material,0.7-2.8 mmol?L-1 silicon were sprayed on seedlings in the incubator of 5 000 lx and effects of silicon on the growth and related physiological parameters under low light stress were conducted.The results showed that under light stress,spraying 0.7-2.8 mmol?L-1 silicon on leaves promoted nitrate reductase activities and soluble protein contents,resulting in photosynthetic performance improvement.Spraying 1.4-2.8 mmol?L-1 silicon on leaves inhibited seedling spindly growth and seedling plant height,internode length and hypocotyl length reduced significantly,while stem diameter and root and leaf matter accumulations increased.Spraying 1.4 mmol?L-1 silicon on leaves was the best to cultivate strong seedlings.So spraying 1.4 mmol?L-1 silicon on leaves could be the reference index during melon seedling period of early spring greenhouse crop cultivation.
