【Abstract】 By using of the nursery technology shading with nylon net ,seedlings from 15 geography provenance and 61 families,were trailed with random block sampling The biomass of seedling were analzed by means of variance analysis,multi-ply comparatively and cluster analysis. The results shown that the differences among different provenance and family in seedling heigth, biomass of upper ground and underground, stem size,the number of branches,shoot height,the fresh and dry weight are significant. The most suitable provenance such as Dehua of Fujian,yongtai,xianyou,and 21 excellent families were selected from the provenance trails.更多还原
