That's about 1.5m/h in the light, and Castor plants get to a few meters, so I guess it might take a few hours to get from root tips to stomata. – naught101. Nov 17, 2015 at 0:19. Add a comment. WebTranspiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface; it creates negative pressure (tension) equivalent to –2 MPa at the leaf surface. eaglehawk victoria weather
