  • BACKGROUND: This study was carried out in order to closely examine the influence of fertilization upon growth in container of seedling in indeciduous Quercus species (Q. mysinaefolia, Q. acuta and Q. glauca). METHODS AND RESULTS: Fertilizer level was made by adjusting water soluble compound fertilizer (N:P:K=19: 19:19, v/v) to 1000, 2000, $3000mg{\cdot}L^{-1}$ level along with non-fertilizing plot. Fertilization increased height, root collar diameter growth, and dry weight in these three species of trees. The more increase in fertilizer level led to the more rise even in growth of these species. H/D ratio and T/R ratio also showed tendency of getting bigger in the more rise in fertilizer level. Photosynthetic rate was shown to get higher in the higher fertilizer level according to fertilization in all the three species. In the analysis of root morphological traits, the total root length was surveyed to be longer in the more rise in fertilizer concentration. As even a case of root project area, surface area, and root volume is the similar tendency to characteristics in the total root length, a rise depending on fertilization was observed. CONCLUSION: In light of the results in this experiment, the fertilizer level is judged to be $2000mg{\cdot}L^{-1}$ level that is proper for production of 1-year-old container seedling in indeciduous Quercus species with excellent root development and high seedling quality index.
