in order to evaluate the effect of terminal water deficit stress on leaf traits and their relations to grain yield in different barley genotypes (‘yousof’, ‘fajr30’, ‘nosrat’, ‘pbyt-46’, ‘pbyt-97’ and ‘morocco’), two separated experiments were conducted in stress (water withholding from anthesis towards the end of growing season), and non stress (normal irrigation) conditions based on rcbd with...

Conservation of water is critical to the ecological success of Drosophila species living in the drier montane localities of the Western Himalayas. We observed clinal variation in desiccation resistance for both sexes of Drosophila kikkawai from an altitudinal transect (512-2226 m above sea level). Since more than 90 per cent of body water is lost through cuticular transpiration, the target of s...

Factors that affect water loss rates (WLRs) are poorly known for organisms in natural habitats. Seed-harvester ant queens provide an ideal system for examining such factors because WLRs for mated queens excavated from their incipient nests are twofold to threefold higher than those of alate queens. Indirect data suggest that this increase results from soil particles abrading the cuticle during ...

Water conservation is a significant physiological problem for many insects, particularly as temperature increases. Early experimental work supported the concept of a transition temperature, above which water-loss rates increase rapidly as temperature increases. The transition phenomenon was hypothesized to result from melting of epicuticular lipids, the main barrier to cuticular transpiration. ...

The water permeability of the leaves of three deciduous plants (Acer campestre, Fagus sylvatica, Quercus petraea) and two evergreen plants (Hedera helix, Ilex aquifolium) was analysed in order to assess its role as a mechanism of drought resistance. Cuticular permeances were determined by measurement of the water loss through adaxial, astomatous leaf surfaces. Minimum conductances after complet...

asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...

DELUCIA, E. H., and G. P. BERLYN. 1984. The effect of increasing elevation on leaf cuticle thickness and cuticular transpiration in balsam fir. Can. J. Bot. 62: 2423-2431. First-year needles and stems of Abies bnlsnmecr were collected at the end of the growing season along an elevational gradient on Mt. Moosilauke, NH. Tissue was sampled from the base (732 rn), rnidslope ( I 143 rn), forest lim...

Flies of the genus Drosophila inhabit a wide range of habitats, from the tropics to deserts to boreal forests. The primary physiological mechanism allowing Drosophila and other insects to survive in arid habitats is a reduction in rates of water loss. To understand mechanisms of water retention in greater detail, we investigated the three main routes by which Drosophila lose water: excretion, c...

Abstract Key message We identified two poplar clones of the same species as highly comparable, yet further genus to be distinctly different regarding multiple morphological and ecophysiological traits. Leaf morphology, wax composition, residual (cuticular) transpiration four (two hybrid P. × canescens , trichocarpa euphratica ) were monitored from beginning end growing season 2020. A pronounced...

Water-loss rates increase after mating in queens of the harvester ant Pogonomyrmex barbatus (Formicidae: Myrmicinae), then increase again after the mated queens excavate an incipient nest. We determined the mechanistic basis for these increased water-loss rates by examining cuticular permeability, respiratory water loss, metabolic rates, and cuticular hydrocarbons for queens at three stages in ...
