Abstract: The influence of ground-diameter of stock on height growth, diameter growth, rightness rate of scion were analysed in the annual Cunninghamia lanceolata clonal seed orchard in Jinhua Forest Farm. The results show that(1) the height growth of scion has a significant correlation with the ground diameter of stock, and(2) the diameter growth and the rightness rate of scion increase with ground diameter of stock.

Key words: STOCK QUALITY, SCION, SEED ORCHARD, CUNNINGHANIA LANCEOLATA
