Periodicity of xylem growth of rubberwood (Hevea brasiliensis) grown in Malaysia

A study on the periodicity of xylem growth in rubberwood tree at a plantation at University Putra Malaysia, Serdang, Malaysia, was conducted using a dendrometer and, pinning and knife-cutting methods. From the dendrometer readings, actual radial growth showed no substantial increase during the first...
