Abstract

Water deficit stress is known as one of the factors limiting the growth and production of crops in Iran. The potassium element plays an important role in plant vital activities and inhibits the destructive effects of low water stress. Use of nanofertilizer in order to accurately control the release of nutrients, can be an effective step towards achieving sustainable agriculture and compatible with the environment. The aim of this study was to investigate the physiological traits influenced by potassium nano-chelated on dehydration tolerance in wheat. For this purpose, a factorial experiment was conducted in a completely randomized design in a laboratory of Faculty of Sciences, University of Mohaghegh Ardebili, in 2015, with three replications. The first factor was Water deficit at three levels of osmotic potential of 8-, 4-, 0 times, , the second factor included two Rasad and Gascogne cultivars and the third factor was potassium nano-chelated with concentrations of 0, 35 and 65 mg / L. The stress was conducted at stage 3 to 5 leaf. First sampling five days after applying low water stress by Polyethylene glycol 6000 and the nano-chelated potassiom spray solution was applied to the leaves. The results showed that the stress increased the activity of the enzymes catalase, peroxidase, polyphenol oxidase and ascorbate peroxidase and Metabolites such as soluble sugars, proline and total protein. The Cascogen cultivar showed significant changes in most of the measured traits compared to the observation Rasad significant changes, as a result, this cultivar was considered to be tolerant to water stresses. In general, the application of concentration of 65 mg / L of potassium nano-chelated decreased the effects of stress on measured traits and in some cases, it increased plant defense mechanisms in response to destructive effects of stress such as increasing the activity of antioxidant enzymes and plant adaptation Metabolites. Among the concentrations used by nano-chelated, 65 mg / L had the highest effect in 8-barrel stress and could be recommended for farmers in terms of impact.
