Overview

What is HydroShoot about?

HydrShoot is a functional-structural plant model that simulates the interactions between shoot’s hydraulic structure, gas-exchange and energy-budget, at the organ level.

Plant shoot is static to HydroShoot. That is the model does not simulate plant growth nor its development. Its usage would therefore be only sound only if shoot’s structure can be assumed constant across a given span of time (let’s say a week or so for grapevine).

Why would you be interested in it?

HydroShoot may be useful for example if you would like to explore:

  • how leaf net carbon assimilation rate (\(A_n\)), transpiration rate (\(E\)), temperature (\(T\)) and bulk water potential (\(\Psi_{leaf}\)) interact across the canopy
  • how soil water status impacts \(A_n\), \(E\), \(T\), and \(\Psi_{leaf}\)
  • how the structure of the shoot impacts \(A_n\), \(E\), \(T\), and \(\Psi_{leaf}\)
  • how soil water potential (\(\Psi_{soil}\)) propagates across plant’s shoot
