Table 3 Tree ring parameters for ring width (RW), latewood percentage (LWP), earlywood density (EWD), and latewood density (LWD)

From: Internal-check variation in boxed-heart square timber of sugi (Cryptomeria japonica) cultivars dried by high-temperature kiln drying

Cultivar	Sample	RW (mm)		LWP (%)		EWD (kg/m³)		LWD (kg/m³)
Cultivar	Sample	Mean	SD	Mean	SD	Mean	SD	Mean	SD
Yabukuguri	Y1	5.85a	0.81	32.1a	3.4	356b	23	752c	29
Yabukuguri	Y4	4.45b	0.50	34.4a	3.0	383a	22	797b	23
Kumotooshi	K1	2.44d	0.75	32.1a	6.1	347c	44	816a	29
Kumotooshi	K4	2.68c	0.15	29.6b	1.9	334c	14	797ab	21

There were significant differences among the samples of Y1, Y4, K1, and K4 for RW, LWP, EWD, and LWD (P < 0.001) using ANOVA. Different letters, a, b, c, and d show significant differences using the Tukey–Kramer HSD test (P < 0.05)
