Impact of different light levels on growth and physiology of Cyclobalanopsis multinervis
Abstract: This thesis investigated the different light impact on growth and physiological of Cyclobalanopsis multinervis seedlings through three illumination level processing for multiple pulse cyclobalanopsis greenhouse container seedling ,measuring its amount of growth,rapid light curve,leaf quality,stomatal density,chlorophyll, analysis the different light impact on growth and physiological of Cyclobalanopsis multinervis. The proper shading is beneficial to seedling growth, increase the chlorophyll content of leaves. Quick light response curve test showed that the ETR under the light is 149μmol • m-2 • s-1 and the ETR under the bed is 151.3μmol • m-2 • s-1,they have no significant difference. The experimental results show that, Although Cyclobalanopsis multinervis is heliophytes plants,the seedling stage appropriate shading is beneficial to the growth .
