Oil palm AGB components, turnover and measurement. (a) Biomass turnover and stocks across a 25-year planting cycle. (b) An upright Young Mature oil palm with DBH (measured at 1.3 m excluding frond bases) and trunk length to the frond ranked 33 (L33) indicated. (c) Labelled frond diagram, (ci) indicates frond rank numbering and crown phyllotaxis (after Aholoukpè et al., 2013), (cii) demonstrates PCS (petiole cross sectional area) measurement where PCS = U × V, a rachis fragment is taken from the rachis midpoint.
