Do we need to fit threshold tension to plant and cultivar (vegetable, fruit trees, flowers, turf)?

Very likely yes because of the hydraulic resistance to water flow in

transpiration. More research is needed to evaluate the quantitative aspects of

the relation between hydraulic resistance and water potential in various plant

species. Water flows trough the plant in xylem vessels. The hydraulic

resistance is dependent on the anatomy of xylem vessels and the length for

water transport that are different in various plants. The higher the hydraulic

resistance a lower water tension is required to enable sufficient transpiration

and stomatal opening for photosynthesis.
