Effect of Light Intensity on Leaf-color Expression of Acer truncatum Bunge

LIANG Feng,LIN Yin-ding(College of Forestry,Shanxi Agricultural University,Taigu Shanxi 030801,China)  
Light is one of the factors causing the leaf-color's variety.It influence the expression of leaf color and the growth through affecting plant pigment synlhesis is and adjusting relative enzyme activity.This experiment researches the effect on leaf-color's expression of Acer truncatum Bunge through adopting different light intensity treatment.This paper analyzed the effect on leaf-color's expression of Acer truncatum Bunge by determining the variety of chlorophyll's content,soluble sugar's relative content and anthocyanin's relative content in leaves of Acer truncatum Bunge under different light intensities.The result showed that the content of anthocyanin and soluble sugar is maximum;the chlorophyll's content is minimum,the leaf-color's expression is best and has the view and admires quality under the full light intensity.
