2.5.4 Leaf area
Leaf area is the total leaf area per plant and is
a function of the rate of leaf formation, the
size of individual leaves, and their longevity.
A number of methods are used to estimate
total leaf area.
• Visually rate the, total photosynthetically
active leaf area based on the leafyness of
the plant, instead of measuring the actual
leaf area. This gives an approximate
estimation of leaf area.
• Estimate leaf area non destructively by
counting the number of leaves per plant
(C,) and then estimate the area (C,) as the
sum of products of lamina length and
maximum lamina width per leaf
