Principle: -
The transpiration rate (transpiration) is the water from theplant surface live (mainly leaves) with water vapor state lost tothe atmosphere in the process is different, and the evaporationprocess of physics, not only by the impact of the transpirationof environment, but also by the regulation and control of theplant, so it is a complex physiological process.
The main process is: soil moisture, root, root, stem, leafcatheter catheter, catheter to air.
The young plant stomata, all exposed surfaces in air can transpiration.
