The water transport pipeline in herbs is assumed to be more vulnerable to drought than in
trees due to the formation of frequent embolisms (gas bubbles), which could be removed by …

Just as a soggy paper straw is prone to yielding under the applied suction of a thirsty drinker,
the xylem tracheids in leaves seem prone to collapse as water potential declines, impeding …

The Cupressaceae clade has the broadest diversity in habitat and morphology of any conifer
family. This clade is characterized by highly divergent physiological strategies, with …

Xylem hydraulic properties play an essential role in supporting growth and photosynthesis
and influence sensitivity to environmental conditions such as drought and freezing …

Water transport in conifers occurs through single-celled tracheids that are connected to one
another via intertracheid pit membranes. These membranes have two components: the …

Summary 1 Stem vascular system strongly influences structure and functioning of leaves, life‐
history, and distribution of plants. Xylem structure and hydraulic conductivity of branches …

Increases in drought‐induced tree mortality are being observed in tropical rain forests
worldwide and are also likely to affect the geographical distribution of tropical vegetation …

We exposed seedlings of 12 Eucalyptus microtheca F. Muell. provenances to well-watered
and water-stressed growing conditions in a greenhouse experiment and investigated the …

Drought stress can cause xylem embolism in trees when the water potential (Ψ) in the xylem
falls below specific vulnerability thresholds. At the alpine timberline, frost drought is known to …

Xylem vulnerability to cavitation differs between tree species according to their drought
resistance, more xerophilous species being more resistant to xylem cavitation. Variability in …
