although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. in any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. in the present study, air pollution tolerance index was calculated for var...
Abstract: In order to evaluate the effect of drought stress and salicylic acid on mineral content and some physiological traits of soybean genotypes (Glycine max L.) a greenhouse experiment was conducted as factorial based on completely randomized design with three replications in Mohaghegh Ardabil University in 2014. The first factor consisted of three levels of water deficit (85%, 65% ...
To reduce transpiration and increase water use efficiency of olive trees in Ahvaz, the antitranspirant effects of of three levels of kaolin (0, 2.5% and 5%) on four varieties of olive (Mission, Conservolea, Keylet, Bledy) was carried out in a four-month period, with three replications. The results showed that Kaolin have a significant effect on plant water potential, leaf relative water content...
An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...
Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...
evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...
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...
this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...
