Pea cultivation in autumn has a higher yield compared to its spring cultivation. In order to investigate the possibility of changing the planting date of chickpea from spring to autumn in (Kerman province, Iran) and obtaining cultivars that could withstand cold winter and produce more yield, 63 chickpea genotypes were planted in pots at Dec/2016 and evaluated in field .The agronomic traits inc...
Cucumber is a warm season crop that suffers from chilling injury at temperatures below 10°C. In recent years, jasmonates have been used for reduction of chilling injuries in plants. An experiment was, therefore, conducted to test whether methyl jasmonate (MeJA) application at various concentrations (0, 0.05, 0.1 and 0.15 mM) through seed soaking or foliar spray would protect cucumber seedlings,...
Seed pretreated with plant growth regulators can improve germination parameters, growth, and yield of crops. Thus, in two greenhouse and field experiments, effects of seed treatment with 0.1 mM salicylic acid (SA), 1µM methyl jasmonate (MJ), 1.5% humic acid (HA), and water (as Control) on germination parameters, seedling growth, and also growth and fruit yield were studied. In the first experim...
Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
Peach is a highly corrosive fruit with a short shelf life (less than 7 days at room temperature)susceptible to diseases, pathogens and physical damage. The storage or marketable life ofhorticultural crops can be extended by various treatments applied to them after and/or beforeharvesting. Fruits are usually treated with a range of materials [(e.g. salicylic acid (SA)] to...
the computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. the program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area s = 1 m × 1 m = 1 m2, cell pair number n = 300 pairs). the stack operatingconditions are optimized. seawater a...
This paper presents the effect of natural aging upon the performance of the polymeric insulat ion materials made from Epoxy resins, Polydimethylsiloxane (PDMS), and Rice husk ash compound. The sa mples of epoxy resin insulation material consist of Dig lycidyl Ether of Bisphenol A (DGEBA), Meta Phenylene Diamine (MPDA) as curing agent, and 325 mesh Rice Husk Ash (RHA) as filler, treated with var...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
Flat-panel detectors using amorphous silicon p-i-n diodes have been developed for chest and therapeutic portal imaging. In radiation therapy, an imaging device is exposed to a high radiation dose. The radiation damage affects the leakage current of diode and may decrease the whole system performance. In this research, we have investigated the radiation damage to the leakage current of a-Si : H ...
Antifreeze glycoproteins (AFGPs), found in the blood of polar fish at concentrations as high as 35 g/liter, are known to prevent ice crystal growth and depress the freezing temperature of the blood. Previously, Rubinsky et al. [Rubinsky, B., Mattioli, M., Arav, A., Barboni, B. & Fletcher, G. L. (1992) Am. J. Physiol. 262, R542-R545] provided evidence that AFGPs block ion fluxes across membranes...
