Abstract:

To investigate the effect of different light intensity on growth and seedling quality of Idesia palycarpa Maxim container seedlings, this test used different transmittance of shading screen to shade Idesia palycarpa Maxim container seedlings. The results showed seedling height of Idesia palycarpa Maxim container seedlings under 100%, 60%, 40% light conditions was significantly higher than that of 20%, 5% light conditions; Before June 30, difference of ground diameter was not significant under different light intensity, then difference was significant after June 30; In September 30, ground diameter and stem weight under 100%, 60%of light conditions were significantly higher than others; Total biomass and root weight under 100% light intensity were significantly higher than others; All morphological indexes under 100% light intensity were the best, seedling height, ground diameter, root weights and stem weight of annual seedlings were 37.73 cm, 6.58 mm, 1.38 g, 1.83 g, total biomass was the highest (3.61 g). Therefore, to reduce water consumption, Idesia palycarpa Maxim container seedlings were suitable for cultivation under 60% light intensity before June 30, then after June under 100% light intensity for cultivation under60%.
