salinity is the major limiting factor for plant growth and crop productivity. salt stress is effective on physiological characteristics, morphology, anatomy, chemical composition and water content of plant tissue. pulses are the second of food source after the cereals for human. among the pulses, the bean has special importance. in order to investigate the effect of silicon on the physiological...

basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment  investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rat...

In order to reduce errors, error correction codes (ECCs) need to be implemented fast. They can correct the errors corresponding to the first few orders in the Taylor expansion of the Hamiltonian of the interaction with the environment. If implemented fast enough, the zeroth order error predominates and the dominant effect is of error prevention by measurement (Zeno Effect) rather than correctio...

A field experiment was carried out to test the effect of pore water salinity on the macrobenthic assemblages in an estuarine region of the Tagus estuary (Portugal) subjected to wide fluctuations in salinity. The conditions at the experimental site ranged from freshwater (minimum salinity 0.2) to mesohaline (maximum salinity 15.3). The experimental site was affected by an unexpected deposition o...

Given that the characteristic of free floating plants to uptake metals can have a positive effect on the efficiency of the remediation process of a wetland, it is important to investigate the factors that may impact the process of uptake of metals by the plants. By conducting this present study over a short duration of time, the effects of salinity on the growth, the content of the photosynthet...

in order to investigate the effect of zinc element application on growth and some morphophysiological of maize (single cross 704) an experiment was conducted during 2010 at greenhouse. experimented design was complete randomize factorial with four replications. treatments of experiment were soil salinity (4, 8 ds.m-1 and 0 as a control) and different zinc concentration including 0, 10 and 20 mg...

abstract experiment was conducted for 8 weeks to determine the reaction (astacus leptodactylus) to interaction energy and salinity. diets containing 3 levels of energy (300,370 and 450 kcal/100g) with a constant protein content of 30% and 2 levels of salinity (fresh water and brackish water (12 ppt) were formulated. tank content 110 liter, each filled with 80 liter water. 5 a.leptodactylus (ave...

The mixture between two fluids of different salinity has been proven to capable of producing electricity in an ocean salinity energy conversion system known as hydrocratic generator. The system relies on the difference between the salinity of the incoming fresh water and the surrounding sea water in the generator. In this investigation, additional parameter is introduced which is the temperatur...

Salinity is a major environmental stress that limits crop production worldwide. In this study, we characterized plant growth-promoting rhizobacteria (PGPR) containing 1-aminocyclopropane-1-carboxylate (ACC) deaminase and examined their effect on salinity stress tolerance in okra through the induction of ROS-scavenging enzyme activity. PGPR inoculated okra plants exhibited higher germination per...
