Abstract: Using 12 provenance seeds introduced from Argentina in 2002 as materials,the raising seedlings test of Prosopis abla was carried out at the Xuecheng Nursery in Wenchuan County, Sichuan Province. The differences of biomass, growth rhythm and phenophase among 12 provenance seeds at the seedling stage were evaluated. At the same time,test on seedling production with cutting root and apical bud was also conducted. The results showed that the cutting root could promote the growth of root system, and cutting apical bud was good for increasing the diameter of stem and the percentage of lateral branch.

Key words: Prosopis abla, introduction, seedlings observation, cutting root, cutting root and apical bud, raise seedlings
