Inter-clonal and intra-clonal wood properties and their variations from pith to bark were evaluated for wood density and anatomical features on rubber wood (Hevea brasiliensis Muell. Arg) from a 9-year-old plantation with planting densities of 500 and 2000 trees per hectare comprised of clones RRIM 2020 and RRIM 2025. Planting density had uneven effects on wood density and wood cell features. I...

This brief planting season is preferred for several logistical and physiological reasons, yet interest in fall planting has increased as a means to extend the planting season. We evaluated effects of a wide range of planting dates on...
