In Iran, Acacia victoriae is not native to tree in Iran but it is used for important goals such as stabilize hills and the beautify landscape in the southern regions of the Iran, especially in the Khuzestan and Ilam provinces. Researches that include the development of native and non-native trees, which are compatible with the conditions of dusting areas in the western provinces of Iran, are ve...
Salinity is a major environmental factor limiting plant growth and crop productivity. Therefore many studies had been done to minimize the stress effects caused by salinity in agriculture and plant physiology. To access the effect of methyl jasmonate and salinity on peppermint, experiment was conducted as factorial based on a randomized complete design (CRD) with three replications. In this res...
Forty yeast strains isolated from soils taken from different locations in Egypt were tested for their P-solubilizing activities on the basis of analyzing the clear zone around colonies growing on a tricalcium phosphate medium after incubation for 5 days at 25degreesC, denoted as the solubilization index (SI). Nine isolates that exhibited P-solubilization potential with an SI ranging from 1.19 t...
Abstract Purpose Insect herbivory affects plant growth, nutrient and secondary metabolite concentrations litter quality. Changes to quality due insect can alter decomposition, with knock on effects for growth mediated through the plant-litter-soil feedback pathway. Methods Using a multi-phase glasshouse experiment, we tested how changes in shoot root of fast- slow-growing grass caused by herbiv...
Endophytic fungi as the most important soil microorganisms through establishing a symbiotic relationship with various plants play an important role in improving growth and mineral nutrition of their host plants. This research investigates the effect of Piriformospora indica and mycorrhizal fungi treatments on phosphorus efficiency indices and increasing phosphorus deficiency tolerance stress in...
Genus Mentha is represented by 15 taxa in Turkey, most common being Mentha longifolia, M. suaveolens, M. pulegium and M. aquatica. All are perennial herbs, flowering in summer and reproducing with the help of seeds as well as vegetatively. These taxa are widely used by locals as condiment as well as for the preparation of mint tea aginst flue, lung and stomach disorders, whooping cough, and as ...

abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
This research compares the performance of floating systems planted with Vetiveria zizanioides as a hydroponic approach for removing nutrients from two contaminated waters. For this purpose, two pilots with overall net volume of 60 litres were constructed and inoculated by secondary treated domestic wastewater (STDW) and irrigation water obtained from Minab reservoir (IWMR) in batch mode. Regard...
