Adaptation of Grasses to Water Stress-Leaf Rolling and Stomate Distribution

Response of leaf water potential, stomatal resistance, and leaf rolling to water stress.

Numerous studies have associated increased stomatal resistance with response to water deficit in cereals. However, consideration of change in leaf form seems to have been neglected. The response of adaxial and abaxial stomatal resistance and leaf rolling in rice to decreasing leaf water potential was investigated. Two rice cultivars were subjected to control and water stress treatments in a dee...

Water stress of sugarbeet as related to leaf and canopy temperatures and to leaf Water content

The Permeability of Non-stomate Leaf Epidermis to Carbon Dioxide.

It has been generally assumed that the exchange of gases between the intercellular spaces of leaves and the external atmosphere occurs to an appreciable extent only when the stomates of the leaves are open. However, attempts to correlate the observed rate of CO2 absorption either with the number of stomates per unit area or with stomate area have met with only limited success. VERDUIN (16) beli...

Adaptation of Leaf Water Relations to Climatic and Habitat Water Availability

Successful management of forest systems requires a deeper understanding of the role of ecophysiological traits in enabling adaptation to high temperature and water deficit under current and anticipated changes in climate. A key attribute of leaf water relations is the water potential at zero turgor (πtlp), because it defines the operating water potentials over which plants actively control grow...
