Act

* Allometric Formulations: Petiole Cross-Section Area = W × D. Frond Leaf Area (m²) = (2 × Pinnae × Length × Width × 0.55) / 10,000. Frond Dry Weight FDW (kg) = 0.1023 × (P × D)^0.749.

Executes MPOB morphometric allometric transformations on Frond 17 measurements to compute mean crown dimensions, annual frond biomass (FDW), and stand canopy Leaf Area Index (LAI).
