Wheat is the first among cultivated crops in terms of hectare in Iran, and is cultivated on 6.2 million hectares under variable agro-climatic conditions. Of 2.2millions hectares of wheat crop grown under irrigation system, about 30% of the areas experience the adverse effects of salinity stress, which is one of the limiting factors of wheat production in warm and temperate regions of Iran. Sel...

A greenhouse factorial experiment was conducted in completely randomized design (CRD) with three replications to investigate the effect of soil Zn deficiency stress on the expression of three genes involved in the synthesis of metal chelating agents (NAS1, NAS2 and NAS3) in bread wheat. Hamoun and Hirmand (Zn-efficient and inefficient cultivars, respectively) cultivars were planted under Zn def...

This research was conducted to study the role of phenology in wheat cultivars’ reaction to salinity stress. The experiment was carried out as factorial, based on a randomized complete block design with three replications, in Bu-Ali Sina University, Hamadan, Iran. Treatments included four wheat cultivars (Alvand, Toos, Navid and Sayson) and five levels of water salinity (0, 4, 8, 12 and 16 dS/m)...

Salinity stress is one of the environmental factors limiting plant growth and development and has negative effects on morphological and physiological parameters of plants. Therefore, various compounds have been used to reduce the harmful effects of this stress. According to previous studies, metal nanoparticles have both negative and positive effects on different plant species. The aim of this ...

Cadmium as an environmental pollutant heavy metals have effect on morphological and physiological activities in plants. Selenium, an essential element had beneficial effects on enhanced tolerance in plants against environmental stresses. In the investigation, from Cadmium chloride concentrations 0, 350, 700 µM supplied with added to soil and Sodium selenat 0, 1.5, 3 mg L-1 as a foliar applicati...
