FIGURE 5 . Water budgets by leaves of Capparis
odoratissima . (a) Normalized leaf weight variation (proportional to the
initial leaf weight) of the leaves of Capparis odoratissimacomparing different treatments: blue filled dots represent the maximum
weight increase of immersed leaves after the wet cycle (dark blue), and
minimum weight variation after the dry cycles (light blue); note that
both follow a linear positive rate over time. Empty circles represent
weight loss under epidermal evaporation (black), when 30% of the
adaxial surface was covered with droplets (yellow), and when 30% of the
abaxial surface was covered with droplets (red). Slopes (a) are shown
for comparison and have units of h-1. (b) Cumulative
water uptake by leaves loaded on the adaxial (yellow) or the abaxial
(red) surfaces. Bars represent standard errors at a p ≤0.95.
