Equation

As printed (Table 3 ('.' = no intercept; RSE in kg))

Astrocaryum AGB Hstem . 21.302 0.957 18 26.1

In this library's units, ready to compute (kg)

Aboveground biomass = 21.302 * Hstem
Hstem
Palm stem height, ground to the lowest leaf, m

Hstem = stem height to the base of the lowest leaf (m), fitted range 1.5–9.0 m. Linear model, no log correction.
