Growth Rates of  Morphometric Variables in Approximately Linear Sections Using Lines in R³

Table 1

Quantities associated with the analysis of growth in plants.

Quantity	Instantaneous value	Mean value in the interval (approximate)	Dimension
TAC			m t^−1
TRC			m m^−1 t^−1
TAN			m A^−1 t^−1

 = growth indicator, t = time, TAC = absolute growth rate, TRC = relative growth rate, TAN = net assimilation rate, and A: leaf area.
