Leaf hydraulics. (2006, background): “Where root pressure is not operating, an active mechanism may exist for embolism refilling even when xylem tensions exist, involving ion pumping or transient pressures, associated with increasing starch degradation (25, 124, 149).”
A synthesis of tree functional traits related to drought-induced mortality in forests across climatic zones (2017, background): “Of the trait studies exploring drought resistance in savannas (Stratton, Goldstein & Meinzer 2000; Bucci et al. 2003; Hao et al. 2008), few have linked traits to mortality.”
Carbon dynamics in trees: feast or famine? (2012, background): “There is increasing evidence that NSCs, particularly sugars, may be involved in the sensing (Secchi and Zwieniecki 2011) and reversal (Bucci et al. 2003, Nardini et al. 2011) of embolism.”
Different ability of three Mediterranean oak species to tolerate progressive water stress (2006, background): “Modulation of gas exchange in relation to the variation of hydraulic resistances of leaves, stem, and roots pointed out a well-triggered above- and under-ground mechanism allowing a good water balance for oak species (Bucci et al. 2003, Buckley et al. 2003, Katul et al. 2003, Lo Gullo et al. 2003).”
The control of stomata by water balance. (2005, background): “Recent data showing that embolised vessels can be re-filled quickly and under tension (McCully et al., 1998; Tyree et al., 1999; Melcher et al., 2001; Bucci et al., 2003; Brodribb & Holbrook, 2004) suggest that mid-day cavitation need not irreversibly reduce gs in the afternoon.”
Diurnal depression of leaf hydraulic conductance in a tropical tree species (2004, unknown): “Although several studies have observed diurnal cycles of cavitation and recovery in the petiole (Zwieniecki et al. 2000; Bucci et al. 2003), this is the first time that the leaf lamina has been shown to undergo diurnal cycles of loss and recovery of hydraulic”
Xylem hydraulic safety margins in woody plants: coordination of stomatal control of xylem tension with hydraulic capacitance (2009, unknown): “However, the hydraulic resis- tance of leaves is substantial (Sack & Holbrook 2006) and dynamic over a daily time scale (Bucci et al. 2003; Brodribb & Holbrook 2004a; Woodruff et al. 2007), resulting in a substantial and variable transpiration-induced disequilib-*Correspondence author.”
The spatial pattern of air seeding thresholds in mature sugar maple trees (2005, background): “In leaf veins and petioles, which have a relatively high proportion of primary xylem, the continued function of primary xylem conduits may be of greater importance, but it appears that plants have substantial ability to repair cavitated conduits in these organs (Zwieniecki et al. 2000; Bucci et al.”
