3.2 Photosynthetic gas exchange parameters
In cucumber plant, an increase in stomatal conductance and a decrease in
stomatal resistance and water use efficiency were detected which were
statistically significant (p ≥ 0.01). In wheat plant, a
significant decrease was observed in net assimilation rate,
transpiration rate and stomatal conductance, while treatment with
amaranth leachate led to significant increase (p ≥ 0.01) in
stomatal resistance and water use efficiency in comparison to the
control (Table 3).
