Definition of transpiration stream in English:
The flow of water through a plant, from the roots to the leaves, via the xylem vessels.
- The transpiration stream through the xylem transports cytokinins, as well as ABA, from the root to the shoot.
- Xylem flow carries the transpiration stream and is normally entirely acropetal.
- This scenario implies that water will be taken up by the xylem parenchyma whenever the water potential in the transpiration stream is high.
