Abstract:
The effect of LED (R/B 5∶1) on the morphological and physiological characteristics of tomato seedlings under different light supplies were studied,in order to provide reference for tomato.The results showed that after 15 and 30 days,the effect was not obvious,and after 45 days,the effect was obvious in the period of 15:00—19:00,the fresh weight,leaf area,stomatal density,chlorophyll,soluble protein content,soluble sugar content and root activity were significantly higher than those of control or other treatments,and the plant height and MDA content were significantly reduced,the next was 19:00—23:00 light supply treatment.
