From Fig. 3, the TS of stem powder was the lowest, followed by leaf blade powder and leaf sheath powder. Only stem powder met the requirement for MDF (JIS A5905, 2014), although not all types of raw materials could meet the requirement for particleboard (JIS A5908, 2003). The stem part revealed lower TS than the leaf sheath part, reflecting that the stem appeared to have a thicker waxy layer than leaf sheath (Inglesby et al., 2005). WA values showed the same trend as TS values.
