Objective: Salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. This study was undertaken to investigate salt tolerance in Salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. Methods: This study had two parts of greenhouse and natural habitats. The treatment s...

cantaloupe is a common crop and relatively important in iran which show high genetic diversity. forty nine genotypes including seven iranian endemic cantaloupes rishbaba, shahabadi, samsori, dastjerdi, magasi, tiltorogh and savei and their direct and reciprocal crosses were evaluated during two years using triple lattice design. results indicated the positive and significant correlations betwee...
Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...
A feasibility study with three pre-conditioning times was carried out to examine the effect of anaerobic pre-treatment on phosphorus removal by aeration. The results showed that soluble phosphorus could be decreased from 120 mg L−1 to about 40 mg L−1 within one-day aeration. However, soluble phosphorus concentration was found not affected by pre-conditioning, but more pH dependent. Anaerobic pr...
ABSTRACT: Edible coatings made from whey protein concentrate (WPC) and gellan gum (G) were investigated for their capacity to preserve the quality of Malus domestica cv Golab apples. WPC and gellan gum coatings at different concentrations plasticized with glycerol (Gly) were tested. Postharvest storage quality condition testes included weight loss, color and texture changes, titratable acidity ...
in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...
Fruits and vegetables contain an array of antioxidant compounds. In this experiment, the effect of pomegranate, grape and kiwifruit juice or extract viz., pomegranate husk on pear fruits were investigated and compared with chitosan 1.5% and distilled water (control). The changes in the ascorbic acid, total soluble solids, total acid, weight loss, firmness and peroxidase and polyphenol oxidase a...
numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. however, most of them address the problem from macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. the present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle level. a...
Chitosan in addition to antimicrobial properties is used as an edible coating for improvement storage life of various fruit and vegetables. Weight loss and fungal rot, are the main limiting factors in sweet pepper postharvest life. Therefore in this study the effects of chitosan at concentration of 0.5, 1, 1.5 and 2% were investigated on the quality preservation and fungal rot controlling of sw...
