This book discusses the influence of drought on the xylem anatomy, hydraulic conductivity in petioles and stomatal density of leaves of four Vitis vinifera cultivars (Syrah, Silvaner, Grenache and Airen). The results discussed are based on research undertaken with field-grown grapevines exposed to two different irrigation regimes. Data is analyzed using open source software, creating a pipeline that automatically identified and measured individual xylem vessels.
