     Mutations induced by gamma irradiation are part of improving some important agronomic traits in crops.  Identifying the optimal mutagenic dose is considered to be the most crucial step in trials and generating mutated genetic materials. The goal of this study was to evaluate the effect of different doses of gamma ray (0, 150, 200, 250 and 300 Gy) on some plant early stages traits and bioch...

Abstract In calcareous and saline soils, the adverse effect of some ions such as bicarbonate, boron, magnesium, and especially sodium, and the imbalance of nutrients’ concentrations are essential factors which reduce plant growth. A greenhouse experiment was conducted to study the effect of sodium (Na) and magnesium (Mg) on some growth traits and chlorophyll content of pistachio seedlings (cv....

The aims of this study were to investigate genotypic variations in root traits at phytomer level of wheat varieties and for recommending a few root traits as selection parameters in future breeding programs. Two separate experiments were conducted to measure their root traits for hydroponically grown wheat plants. In Experiment 1, main axis length, root hair density and diameter differed from p...

Physiological traits associated with drought tolerance are useful as surrogate traits for drought tolerance. Information on the association of root traits and water use efficiency (WUE) and plant growth in sugarcane is rather limited. The objective of this study was to evaluate genotypic variation for root traits, WUE and growth characters of above ground parts of sugarcane. A 2 × 10 factorial ...

Salinity is one of the most important factors limiting agricultural production. Cotton, as an oil-fiber plant, is one of the most important industrial plants and is sensitive to salinity, especially at germination and seedling stages. Therefore, in this study, 14 allotetraploid varieties of commercial and local cotton were selected. The study was carried out as factorial with a completely rando...

s: Chromium is one of the unessential heavy metal that makes high toxicity in the plants. The aim of this study was assaying the changes that come from toxicity of (Cr ) on some biochemical, physiological and 6+ ionic specification of Brassica napus variety sari flower. The tests were conducted at hydro ionic conditions and at 0, 25, 50, 75 and 100 μm concentration of K CrO with four repeats in...

Background and objectives: The application of growth-facilitator materials to improve germination, early establishment, and plants growth can increase the success of rangeland improvement, planting, and pasture construction projects. In addition, growth facilitators can improve the quantity and quality of vegetation cover and production in dry-farming lands by increasing the success of cultivat...

The watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] cultivar Crimson Tide and 7 different gourd genotypes [Cucurbita maxima, C. moschata, Luffa cylindrica, Benincasa hispida, Lagenaria siceraria landraces (Skp and Birecik), and L. siceraria hybrid (FRGold)] with rootstock potential for watermelon were grown under saline conditions (0, 4, 8, 12, and 16 dS m) to investigate the response...
