Vapor pressure deficit affecting water utilization rates

Submitted by Elsewhere on 2020-Sep-11 Fri 09:48

Vapor pressure deficit (VPD) represents the 'pressure' that air puts on the plant to transpire and move air from the roots through the plant and out the stomata in their leaves. When the air is dry (low humidity) and the VPD is high, there will be more pressure on the plant to transpire and keep up with…
