Table 2 Coefficients of correlations between growth traits and amount of phytohormones

From: Seasonal variations of tracheid formation and amount of auxin (IAA) and gibberellin A4 (GA4) in cambial-region tissues of mature sugi (Cryptomeria japonica) cultivar grown in a Nelder plot with different tree densities

	Amount of IAA				Amount of GA4
	June	August	October	December	June	August	October	December
H	0.38	0.07	0.62^*	−0.07	−0.31	0.06	−0.26	0.36
DBH	0.69**	0.39	0.64*	−0.29	−0.05	0.17	0.05	0.37
H/D ratio	−0.83**	−0.55*	−0.70**	0.15	−0.11	−0.20	−0.34	−0.44
CL	0.74**	0.54*	0.57*	−0.40	−0.12	0.29	0.26	0.36
HCB	−0.70**	−0.70**	−0.23	0.51	−0.09	−0.36	−0.61*	−0.11

Coefficient of correlations were obtained from 15 sample trees. H, DBH, H/D ratio, and HCB were the same, as shown in Table 1
