stomatal conductance
Leaf breathing rate
Stomatal conductance is a measure of how readily gases pass through the stomata—the tiny pores on plant leaves that regulate gas exchange.
Higher stomatal conductance means stomata are more open, allowing greater uptake of carbon dioxide for photosynthesis but also more water loss through transpiration.
Plant scientists use this measurement to assess plant water status, drought stress, and photosynthetic capacity.
The crop showed reduced stomatal conductance during the afternoon heat.
