Table 2. Simple correlation coefficients between time of pruning and branching characteristics.

	Time of pruning	Diameter of root	Tree height	No. of branch	Diameter of blanch under winter bud
Time of pruning	1	−0.546**z	−0.864**	−0.399**	−0.582**
Diameter of root		1	0.482**	0.406**	0.503**
Tree height			1	0.341**	0.704**
No. of branch				1	0.137
Diameter of blanch under winter bud					1

Correlation is significant at the 0.01 level.
