Can vegetation optical depth reflect changes in leaf water potential during soil moisture dry-down events?

, 2019
Plant water use strategy is one of the key factors to predict drought impact on vegetation and land-atmosphere fluxes. Vegetation optical depth (VOD) based on microwave radiative transfer inversion has recently been used to assess plant water use ...

Aquaporin regulation in roots controls plant hydraulic conductance, stomatal conductance, and leaf water potential in Pinus radiata under water stress.

Plant, Cell and Environment, 2018
Stomatal regulation is crucial for forest species performance and survival on drought-prone sites. We investigated the regulation of root and shoot hydraulics in three Pinus radiata clones exposed to drought stress and its coordination with stomatal ...

Effect of Leaf Water Potential on Internal Humidity and CO2 Dissolution: Reverse Transpiration and Improved Water Use Efficiency under Negative Pressure

Frontiers in Plant Science, 2017
The pull of water from the soil to the leaves causes water in the transpiration stream to be under negative pressure decreasing the water potential below zero.
