Containerized versus bare-root seedlings of Schima superba for forest regeneration.

Comparisons of survival rate,tree height,and diameter at breast height (DBH) growth of Schima superba using containerized and bare-root planting stock were conducted for good,medium,and poor site conditions. Results showed an interaction between site condition and seedling type was highly significant (P0.01). Survival rate,6-year-old tree height,and DBH growth for containerized seedlings were significantly greater (P0.01)than bare-root stock. Also,in good sites,survival rate,6-year-old tree height,and DBH growth were significantly higher (P 0.01)than medium sites,which in turn were significantly higher (P0.01)than poor sites. Moreover,utilizing containerized seedlings cost 14.6% less than bare-root planting stock. We concluded that for artificial regeneration,containerized planting was advantageous as it had higher survival and growth rates and offered better protection at lower costs.
