Abstract: A scion-producing nursery for 120 plus trees of Carya cathayensi was established by grafting the plus tree scions on Platycarya strobilacea stocks, and the survival rate, growth indices and the shoot numbers from the scions were investigated according to the diameter of the stocks one year later. Survival rate was specially analyzed in the light of the varied periods of time for scion collection and the weather conditions when grafting. It was showed by the variance analysis on SPSS that there were significant differences in the height and diameter growth of the scions because of the stocks diameter. Both of the average yearly height growth and diameter growth of the scions were the greatest (12.08±27.26 cm and 1.52±0.26 cm individually) when the diameter of Platycarya strobilacea stocks was above 8.1cm. The survival rate of the grafted saplings was the highest (61.40±11.87%) as the stock diameter was between 2.1 cm and 4.0 cm. When the stock diameter was less than 2.0 cm, the survival rate, height and diameter growth indices of the grafted saplings were the lowest.
