Phenotypic and Photosynthetic Properties of Distylium buxifolium ‘Limei’ Leaf atDifferent Parts in Summer

Determinations were carried out on phenotype, stomatal density and photosynthetic properties of Distylium buxifolium ‘Limei’ leaves atdifferent parts on August of 2016 in Lisui, Zhejiang province. Results showed that leaves were smaller from the base to the top both from spring andsummer shoot, especially leaf length, width, area and single leaf weight at the top of spring shoot was evident smaller that that at other parts, but ithad no difference of leaf color, stomatal density and size among leaves at different parts. Leaf length, width, leaf area, stomatal density of summerleaves had no evident difference with that of the spring. The experiments demonstrated that the maximum net photosynthetic rate was 11.67-15.01,light compensation point 7.50-17.50, light saturation point 1104-1419 with internode length of 11.33-19.46mm. It showed that D. buxifolium ‘Limei’had advantages of tolerance of trimming, shade and light, and would be a good ground cover plant.
