متن کاملThe permeability to water of the cuticle of the larva of Opifex fuscus (Hutton) (Diptera, Culicidae).
Mosquito larvae have been extensively used as models for the investigation of osmotic and ionic regulation in insects. They are phylogenetically well understood, and have colonized a wide variety of different environments, so that comparative studies have been possible on related species from widely differing habitats. Larval mosquitoes are easily obtained and reared in large numbers, are of co...
متن کاملEffect of Some Bio-Stimulators on Vegetative Growth, Chlorophyll and Leaf Mineral Concentration of Apricot Cv. Shekarpareh
Nutrition of fruit trees during the growing season plays an important role in growth, fruitfulness and fruit quality. Given the increasing application of bio-stimulators as one of the most important approaches towards sustainable agriculture, some bio-stimulators were applied to elucidate their effects on vegetative characteristics and leaf mineral content of apricot trees cv. “Shekarpareh” in ...
متن کاملThe 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...
متن کاملDehydration, water fluxes, and permeability of tobacco leaf tissue.
Removal of the lower epidermis from a tobacco leaf allows a faster and wider range of water fluxes, without damaging the mesophyll. It also permits a more direct examination of the photosynthetic potential of the tissue at various levels of hydration.The rehydration rate of leaf discs is essentially linear. It decreases with leaf age and is correlated with the rate of dehydration, but it is ind...
