Analysis of variance for each parameter

Parameter	Factor
	JK	CR	PP	JK*CR	JK*PP	PP*CR	JK*PP*CR
	Specific gravity	**	**	ns	**	ns	ns	ns
C-set	**	**	**	ns	ns	ns	ns
CSR	**	**	**	*	ns	ns	ns
Thickness swelling	**	**	**	*	ns	**	ns

Note: ns: not significant
significantly different at 5% level
significantly different at 1% level; JK = wood species; CR = compression ratio; PP = pre-treatment.
