In order to investigate the effect of magnesium oxide (MgO) and iron oxide (Fe2O3) nanoparticles (NPs) on physiological traits and the yield of sour tea (Hibiscus Sabdariffa L.), a factorial experiment was conducted in a randomized complete block design (RCBD) with four replications in 2018. MgO and Fe2O3 were used in concentrations of 0.01% and 0.03% as foliar application. The results show...
in order to evaluate the tolerance of pistachio some cultivars to salinity a pot experiment was carried with 2 factors including cultivar and salinity in the year 2013. the cultivars were ghazvini, shah pasand, akbari, khanjari, jandaghi, italiyayi, fndoghi 48, sabz pesteh tohg, ahmad aghayi, rezaie zood res, mousa abadi, ebarahimi, kaleh ghochi and badami zarand. the salinity was applied in fi...
Field studies were conducted to determine the potential for alterations in physiology and the intraspecific variation in sensitivity of 20 wheat (Triticum aestivum) cultivars to enhanced ultraviolet-B (UV-B, 280-315 nm) radiation. The supplemental UV-B radiation was 5 kJ m(-2), simulating a depletion of 20% stratospheric ozone. Out of 20 wheat cultivars (from South China, North China and Mexico...

Due to the beneficial effects of silicon (Si) on ornamental plants, the aim of this study was to investigate the effect of different sources and concentrations of Si on some characteristics of Rose (Rosa hybrida cv. Beverly Watson). This research was conducted in 2015 in one of the greenhouses of Parks and Landscape Organization of Urmia and in Research Laboratories of Horticultural Science Dep...
Fusarium wilt caused by Fusarium oxysporum f.sp. Lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. In order to increase the tolerance to this disease, a triple structure containing PR1, chitinase and glucanase genes controlled by 35S promoter was transferred to tomato. Eight days after planting on pre-culture me...
to study the effect of humic acid and drought stress on some physiological characteristics of roselle (hibiscus sabdariffa) an experiment was conducted in the research field of agricultural education centre of jiroft in 2013. field experiment was carried out as split plot design with three replications. water deficit stress as main factor with three levels (a1 = irrigation after 50, a2 = 100 an...
Nickel (Ni) is an element which has been added recently to the list of necessary micronutrients for plants. But, as a heavy metal, especially at high concentrations, it causes oxidative stress in plants. Knowledge of physiological and biochemical responses of plants to Ni stress can help to understand the mechanisms of adaptability. The effects of Ni on chlorophyll content, proline, soluble pro...
