Table 1 Moisture content and L* value in heartwood of 40-year-old trees

From: Relationship between ¹³⁷Cs concentration and potassium content in stem wood of Japanese cedar (Cryptomeria japonica)

Category	n	Moisture content (%)				L*
		Heartwood		Sapwood		L*
		Mean	SD	Mean	SD	Mean	SD
Total	20	152	57	247	29	62.16	5.54
HMC	6	197	20	232	25	56.11	2.50
LMC	6	76	17	244	21	68.62	1.65
Others	8	176	33	261	34	61.86	3.08

HMC and LMC indicate six highest heartwood moisture-content individuals and six lowest heartwood moisture-content individuals, respectively
n number of samples, SD standard deviation
