Stomatal conductance
Stomata play a major role in water relations and photosynthesis of the plant. this is also true for the water relations of banana, particularly of the Cavendish subgroup (Musa spp., group AAA) [38, 15; 174]. Musa hybrids had intermediate conductance in the afternoon relative to triploids and diploids. But in the morning, conductance was similar in both (lower and upper side) locations. An increased stomatal diffusive resistance was found to be a desirable trait to improve bunch yield of banana in water limited environment [180]. Stomatal diffusive resistance was unaffected by leaf water potential [52]. Ludlow [1986] stated that the main response of increased stomatal resistance by whatever means was to avoid desiccation.
