Background: Salinity is one of the major limiting abiotic stresses that decrease crop production worldwide. To recommend genotypes for cultivation under saline stress conditions, a comprehensive understanding of the genetic basis and plant responses to this stress is needed. In the present study, a total of 20 barley genotypes were investigated to...

The salinity tolerance of 17 breeding wheat genotypes along with three local varieties was evaluated under control and salinity stress (160 mM NaCl) conditions. At the seedling stage, several growth and physiological traits were measured. Moreover, the investigated genotypes were assessed in terms of grain yield across four saline regions during th...

The salinity tolerance of 17 breeding wheat genotypes along with three local varieties was evaluated under control and salinity stress (160 mM NaCl) conditions. At the seedling stage, shoot and root dry weights, relative water content (RWC), membrane stability index (MSI), relative chlorophyll content (SPAD index), root and shoot Na ⁺ (RN and SN),...

Introduction Saffron (Crosus sativus L.) is a perennial and herbs plant, belongs to the Iridaceae family and reproduces via corms (Behnia, 1991). Saffron is native to the mediterranean floristic region, extending eastward into the Iran-Turanian region and lie within the longitude 10°W to 80°E and latitude 30°N to 50°N. These areas are characterized...

ABSTRACT: Previous studies have shown that seeds of some rangeland plant species are dormant at maturity. Seed dormancy is a characteristic that can both help maximize the probability of seedling establishment and spread the risk of recruitment failure across years. In order to investigate the germination properties and seed dormancy of 26 range...

Freezing tolerance of cumin ecotypes was investigated under controlled condition. Six cumin ecotypes (India Rajestan and five Iranian: Ghoochan, Sabzevar, Khaf, Ghayen and Torbate Heydarieh) were subjected to six temperature treatments including 0, -3, -6, -9, -12 and -15 o C. Treatments were arranged in a completely randomized design with three re...

Climate variability and weather extremes are principal sources of fluctuations of annual productivity of many crops in arid and semi-arid environments. Temperature and precipitation are the major weather variables that determine the variability of crop yields. In this study, the relationship between weather descriptors and major irrigated crops yie...

Climate change is considered one of the main environmental concerns of the 21st century. Increased variation and changes in mean temperature and precipitation are expected to dominate future changes in climate and affect crop productivity. It is highly important to identify regions vulnerable to climate change and to identify suitable adaptation pr...

Climate variability adversely impacts crop production and imposes a major constraint on farming planning, mostly under rainfed conditions, across the world. Considering the recent advances in climate science, many studies are trying to provide a reliable basis for climate, and subsequently agricultural production, forecasts. The El Niño-Southern Os...

Current conventional agricultural systems using intensive energy has to be re-vitalized by new integrated approaches relying on renewable energy resources, which can allow farmers to stop depending on fossil resources. The aim of the present study was to compare wheat production in dryland (low input) and irrigated (high input) systems in terms of...

Agricultural drought occurs when there is a deficit in soil water supply to crops. Severe drought limits crop water availability and reduces yield. Rainfed crop production is very vulnerable to drought conditions and farmers in northeast of Iran who heavily depend on their rainfed cereals production usually suffer from drought occurrence. Based on...
