Correlation Between Pruning of Maternal Carya illinoensis Plants and Sprouting in the MaternalScion Plots

Different intensities of pruning were conducted to the branches of maternalscion Carya illinoensis trees to compare the quantity and quality of its bud germination, sprouts and the cuttings obtained, and to conduct the correlation analysis so as to study the influence of pruning on the important indexes of C. illinoensis. The results showed that the number of deposit buds was significantly and negatively correlated with the pruning intensity, i.e., the lighter the pruning was, the more deposit buds would be. There was positive correlation between the number of branches and the effective scions to be formed and the pruning intensity, i.e., the heavier the pruning was, the more branches would be formed and more effective scions might be prepared. Heavy pruning was recommended for maternal C. illinoensis trees in the maternalscion plots.
