Abstract: To reveal leaf adaptability to the light environment for tree species common to the Western Zhejiang,characteristics of the leaf anatomical structure in 15 tree speciesseedlings:Castanopsis sclerophylla,Schima superba,Elaeocarpus decipiens, Sapium sebiferum,Lithocarpus brevicaudatus,Lithocarpus glaber,Phoebe chekiangensis,Quercus phillyraeoides,Podocarpus nagi,Pinus massoniana,Metasequoia glyptostroboides,Taxus chinensis,Photinia fraseri,Lespedeza formosa,and Loropetalum chinense var. rubrum were studied using the paraffin section method and a cluster analysis for leaf anatomical structure. Results showed that: 1)M. glyptostroboides and T. chinensis had an upper epidermis thickness(UET) of one layer with less developed palisade and sponge tissue;Pinus massoniana had needles in bunches of two with a half-ound cross section. 2)The nine broadleaf tree species had the thickest palisade and sponge tissue. Schima superba,Sapium sebiferum,and Podocarpus nagi had one layer of palisade tissue;Lithocarpus brevicaudatus,E. decipiens,Lithocarpus glaber,and Phoebe chekiangensis had two layers of palisade tissue. C. sclerophylla and Q. phillyraeoides had the most developed palisade tissue with three layers. Sponge tissue revealed a loose arrangement. 3)The order for palisade and sponge tissue thickness with shrub species was Photinia fraseri > Lespedeza formosa > Loropetalum chinense var. rubrum. 4)The cluster analysis of leaf anatomical structure showed that Podocarpus nagi was a shade-olerant tree species;Pinus massoniana belonged to a strong positive species;Sapium sebiferum,Photinia fraseri,C. sclerophylla,and Q. phillyraeoides were positive species;and Lithocarpus brevicaudatus,Lespedeza formosa, Phoebe chekiangensis,E. decipiens,Schima superba,M. glyptostroboides,T. chinensis,Lithocarpus glaber,and Loropetalum chinense var. rubrum were classified as neutral tree species. These results provided a developmental basis for the monodominant synusium structural regulation and control of Pinus massoniana and for zonal forest vegetation recovery of low mountain and hill areas.[Ch, 2 fig. 1 tab. 17 ref.]
