Assessing safety margins and hydraulic strategies in Restionaceae: evaluating xylem hydraulic traits in two Elegia species
… xylem vulnerability (P50; MPa) to cavitation and point at which stomata are considered closed (turgor loss point; MPa)) displays the tolerance margins based on plant physiological capacity. Restionaceae have shown extensive evidence of hydraulic niche segregation and are a key demographic of …

Novel water-use strategies of Colorado wetland plants: implications for wetland water loss
… transpiration, and what affects wetland water loss. This paper quantifies the transpiration of five abundant wetland species and investigates physiological mechanisms that drive transpiration rates for each species. The focal species transpire significantly different amounts at the leaf-level …

Balancing the Water Budget: the effect of plant functional type on infiltration to harvest ratios in stormwater bioretention cells
… on 3 critical plant water use traits, the turgor loss point, the point of incipient water stress, and maximum stomatal conductance. A global plant traits meta-analysis identified degree of plant competitiveness and stress tolerance as significant determinants of all three water use traits, …

QUERIES IN QUERCUS: FROM THE DEVELOPMENT OF A TISSUE CULTURE CLONAL PROPAGATION SYSTEM TO THE EVALUATION OF STRESS TOLERANT HYBRID WHITE OAKS FOR THE URBAN ENVIRONMENT
… the gas exchange response and changes in turgor loss points of two tree species (Quercus bicolor and Betula pendula) grown under well-watered and drought conditions in limited soil volume. In response to soil water deficit conditions, Q. bicolor reduced its turgor loss point (osmotic …

Mortality of native forest vegetation in the Kaimai ranges
… of the bulk modulus of elasticity and turgor loss point. Osmotic potential was determined independently from freezing point depression measurement on leaf exudates and similar values were found. The bulk modulus of elasticity and the coefficient of elasticity are closely linked and …

Vegetative Anatomy of Rhododendron with a Focus on a Comparison between Temperate and Tropical Species
… with leaf succulence, and water deficit at the turgor loss point. Idioblast expression was positively associated with leaf capacitance for thin (< 0.5 mm) leaves. Thus, idioblasts can serve as a water buffer for relatively thin leaves. Synthesis–Wood traits of evergreen Rhododendron shrubs …

The response of four ericaceous shrub species to multiple environmental resource variation
… their osmotic potential and water deficit at the turgor loss point seasonally, especially in low water treatments. Low soil water availability also reduced midday conductance and water potential in all four species. Rhododendron maximum and <i>R. catawbiense</i> were very conservative in their …

The Light and Water Stress Tolerance of Two Invasive Legumes: <I>Cytisus scoparius</I> (Scotch broom) and <I>Spartium junceum</I> (Spanish broom)
… junceum and below the water potential value at turgor loss point during midday hours. When water potential decreased, Spartium junceum showed signs of acclimation because stem photosynthesis increased and leaf photosynthesis decreased while C. scoparius did not adjust its rates of …

The combined effects of fertilization and relative water limitation on tissue water relations, hydraulic parameters and shallow root distribution in loblolly pine (Pinus taeda L.)
… resulted in increased capacitance beyond turgor loss, increased relative water content at turgor loss, a more negative turgor loss point, an increased bulk modulus of elasticity, more negative osmotic potential at 100% relative water content, and an increased apoplastic water fraction. As …

The economic challenge of leaf gas exchange
… and growth in a competitive environment, but the loss of too much water can lead to plant death. In this thesis, two aspects of leaf functioning in relation to gas exchange were investigated in terms of these selection pressures, to determine whether observed leaf functioning across species could …
