Arguments

sugarConc

Concentration of soluble sugars (mol/l).

starchConc

Concentration of starch (mol/l)

eqSugarConc

Equilibrium concentration of soluble sugars (mol/l).

temp

Temperature (degrees Celsius).

nonSugarConc

Concentration of inorganic solutes (mol/l).

osmoticWP

Osmotic water potential (MPa).

LAI

Leaf area index.

N

Density (ind·ha-1).

SLA

Specific leaf area (mm2/mg = m2/kg).

leafDensity

Density of leaf tissue (dry weight over volume).

SA

Sapwood area (cm2).

H

Plant height (cm).

L

Coarse root length (mm) for each soil layer.

V

Proportion of fine roots in each soil layer.

woodDensity

Wood density (dry weight over volume).

conduit2sapwood

Proportion of sapwood corresponding to conducive elements (vessels or tracheids) as opposed to parenchymatic tissue.

x

An object of class growthInput.

biomassUnits

A string for output biomass units, either "g_ind" (g per individual) or "g_m2" (g per square meter).

Value

Values returned for each function are:
