Nordin, Nor Azura (2005) Ash and lignin content of Juvenile rubberwood (Hevea brasilensis) / Nor Azura Nordin. [Student Project] (Unpublished)

Abstract

The percentage of ash and lignin content in Juvenile Rubberwood according to difference the height level of tree. These results were in accordance the TAPPI standard.
