TL;DR: The substantial variation in vulnerability to cavitation, evident among individuals, within individuals and within tissues of olive seedlings, was coordinated such that plants with more resistant roots also had more resistant leaves.

TL;DR: An optical method is shown to accurately measure the vulnerability of stem xylem to cavitation during water stress and opens the way to simple, efficient, and reliable assessment of stem vulnerability using standard flatbed scanners, cameras, or microscopes.

TL;DR: It is found that sunflower plants grown under water-limited conditions significantly adjusted leaf osmotic potential, which was linked to a prolongation of stomatal opening as soil dried and a reduced sensitivity of photosynthesis to water-stress-induced damage, and high plasticity in sunflower xylem contrasts with data from woody plants and may suggest an alternative strategy in herbs.

TL;DR: Community‐wide vulnerability segmentation is investigated by comparing leaf/shoot and stem vulnerability in all coexistent dominant canopy and understory woody species in a diverse dry sclerophyll woodland community, including multiple angiosperms and one gymnosperm, finding a lack of hydraulic niche partitioning in this woodland community.
