e0“Compared with plants grown at moderate RH the transpiration rate, stomatal conductance and aperture of high RH grown plants measured at the same condition (40% RH) were, respectively, 112, 139 and 132% in light and 141, 188 and 370% in darkness”

- Intervention effect High humidity grown plants had greater transpiration in light and darkness.
- Intervention effect High humidity grown plants had greater stomatal conductance in light.
- Intervention effect High humidity grown plants had greater stomatal aperture in light.
- Intervention effect In darkness, stomatal conductance was 188% of moderate humidity plants.
- Intervention effect In darkness, stomatal aperture was 370% of moderate humidity plants.
- Intervention effect Guard cells were longer in high humidity plants.
- Observation Stomata responded to desiccation, ABA and darkness in both humidity groups.
- Observation High humidity plants varied markedly in stomatal closure.
- Observation Some high humidity stomata closed fully but others only partly or not at all.
- Mechanism Incomplete closure after ABA suggests ABA deficiency does not explain desiccation response.
