Hydraulic transport

Storyboard

It models the flow of water through the soil-plant-atmosphere continuum (SPAC). Water rises through the xylem driven by gradients of water potential (), from less negative values in the soil to the most negative ones in the leaf. The cohesion-tension mechanism maintains the water column in metastability. Phloem transports solutes in source-sink solution. The model determines the total hydraulic conductance, cavitation under extreme stress and stomatal regulation as an integrative response.
