Container volume affects drought experiments in grapevines: Insights on xylem anatomy and time of dehydration.

ABSTRACT: Plant stress experiments are commonly performed with plants grown in containers to better control environmental conditions. Nevertheless, the container can constrain plant growth and development, and this confounding effect is generally ignored, particularly in studies on woody species. Here, we evaluate the effect of the container volume in drought experiments using grapevine as a model plant. Grapevines grown in small (7 L, S) or large (20 L, L) containers were subjected to drought stress and rewatering treatments. We monitored plant stomatal conductance (g_s ), midday stem water potential (Ψ_s ), and photosynthetic rate (A_N ) throughout the experiment. The effect of the container volume on the stem and petiole xylem anatomy, as well as on the total leaf ar
