Table 3 Mean and standard deviation of measured traits and the result of t-test in measured traits between sites

From: Modeling of radial growth curves and radial variation of basic density in Chamaecyparis obtusa planted in two progeny test sites

Trait	Hitachi		Kiso		p-value
Trait	n	Mean ± SD	n	Mean ± SD	p-value
DBH (cm)	595	15.7 ± 3.4	390	15.6 ± 2.5	0.544
ARW (mm)	595	3.19 ± 0.70	390	3.43 ± 0.58	< 0.001
BD (g/cm³)	595	0.365 ± 0.026	390	0.389 ± 0.025	< 0.001

n, number of individuals; DBH, stem diameter at breast height; ARW, mean annual ring width of all annual ring width; BD, Area-weighted basic density; SD, standard deviation. The p-values were obtained by t-test between progeny test sites
