Leaf xylem embolism, detected acoustically and by cryo-SEM, corresponds to decreases in leaf hydraulic conductance in four evergreen species.
Hydraulic conductance of leaves (K(leaf)) typically decreases with increasing water stress. However, the extent to which the decrease in K(leaf) is due to xylem cavitation, conduit deformation or changes in the extra-xylary pathway is unclear. We measured K(leaf) concurrently with ultrasonic acoustic emission (UAE) in dehydrating leaves of two vessel-bearing and two tracheid-bearing species to ...
متن کاملModelling the outside-xylem hydraulic conductance: towards a new understanding of leaf water relations.
One of the most tantalizing unresolved questions in plant hydraulics is: where does water evaporate within the leaf? While several studies have explored experimental routes to answer this question (e.g. Sheriff & Meidner 1974; Farquhar & Raschke 1978), none have been able to provide a clear answer. In this issue of Plant, Cell & Environment, Tom Buckley has presented a new mathematical model in...

متن کاملInfluence of leaf dry mass per area, CO2, and irradiance on mesophyll conductance in sclerophylls.
Leaf photosynthesis (A) is limited by mesophyll conductance (g(m)), which is influenced by both leaf structure and the environment. Previous studies have indicated that the upper bound for g(m) declines as leaf dry mass per area (LMA, an indicator of leaf structure) increases, extrapolating to zero at a LMA of about 240 g m(-2). No data exist on g(m) and its response to the environment for spec...
متن کاملVariation among Soybean Cultivars in Mesophyll Conductance and Leaf Water Use Efficiency
Improving water use efficiency (WUE) may prove a useful way to adapt crop species to drought. Since the recognition of the importance of mesophyll conductance to CO₂ movement from inside stomatal pores to the sites of photosynthetic carboxylation, there has been interest in how much intraspecific variation in mesophyll conductance (gm) exists, and how such variation may impact leaf WUE within C...
