Relationship Between Biometric Factor of the Host and Giant Piper's Growth (Piper decumanum L.) in the Education Forest of Papua University, Manokwari

The biometric factors of the host, soil properties, microclimate, and biologic components are influencing growth climber Piper species. However, ecological data is rarely available in scientific journals. This research aims to determine relationship between host plant P. decumanum University Papua Manokwari education forest. were acquired using systematic line method, with hypothetical plot sampling tree as center plot. host's factor evaluated partial correlation analysis. Stands a large DBH, high density, rough bark texture preferred by decumanum. number individuals total height increased crown area, branch-free height, skin texture, affected shade area. was limited On other hand, shaded area prevented from growing taller. most probably requires vertical space share same species climbing species, possibly requiring support reach maximum forest canopy. adhesive root's ability cling influenced roughness bark, broad required control microclimate factors.
