in this study the response of 9 rapeseed genotypes were evaluated at the seedling stage using different irrigation levels (50, 70 and 100% fc). a factorial experiment based on rcbd was conducted in the research greenhouses of urmia university with four replications during summer of 2013. some physiological traits such as relative water content, stomatal conductance, transpiration, photosynthesi...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
In order to evaluate the effects of salicylic acid on some physiological characteristics of common purslane (Portulacea oleracea L.) under NaCl stress, a factorial experiment based on completely randomized design with three replications was conducted in 2013 in research greenhouse of Faculty of Agriculture, University of Yasouj, Iran. Treatments were included of six levels of NaCl salinity (0, ...
The effects of 2 concentrations of kinetin, i.e., 2 and 4 mM together with 2 levels of drought stress, i.e., moderate (35% soil saturation capacity) and severe (20% soil saturation capacity) were investigated on the growth parameters of tomato including fresh and dry leaf weight, leaf number, leaf surface area, fruit number, fruit weight, and enzymatic antioxidants. To this end, first tomato pl...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
Cadmium (Cd) pollution is a major environmental and human health threat. Therefore there is a need for cost-effective remediation procedures. Chelators such as humic acid have shown positive effects in enhancing resistance to various stresses. The objective of this research was to investigate the use of humic acids at cadmium-contaminated soil on growth and soluble sugar concentration of aloe v...
In this study, the role of salicylic acid pre-treatment (0.01, 0.1 mM was investigated)in inducing salt tolerance in sweet basil. Results showed germination percentage, length of shoot and root, fresh and dry weight of leaf, and photosynthetic pigments were decreased in response to high salinity but the lipid peroxidation, coefficient allometry, and soluble sugars increased. In plants pre-treat...
In order to investigate the effect of different levels of water stress on Satureja hortensis, a completely randomized design (CRD) with four replications was carried out in the greenhouse of Yazd University in 2014. The water stress treatments including 100, 75, 50 and 25 Percent of field capacity (FC) were applied. The results showed that water deficit stress significantly (p<0.01) decreased p...
In this research, the response of shoot and root of two cultivars of soybean (Glycine max L. cvs Gorgan 3 & Williams) to mild and severe drought was evaluated in pot. Two weeks after of planting, three irrigation treatments including every day (as control), once in three (as mild stress) and five days (as severe stress) were used. The results showed that, stem dry weight, stem and root length, ...
This research was aimed at investigating the effects of foliar application of calcium silicate and sodium silicate on growth and biochemical characteristics and leaf elements of chrysanthemum. This study was conducted as a factorial with completely randomized design and silica source at two levels (calcium silicate and sodium silicate) and concentration of silica at five levels (0 (control), 50...
