in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...

introduction: limited water resources and its salinity uptrend has caused reducing water and soil quality and consequently reducing the crop production. thus, use of saline water is the management strategies to decrease drought and water crisis. furthermore, simulation models are valuable tools for improving on-farm water management and study about the effects of water quality and quantity on c...

Drought, salinity and extreme temperatures are the most common abiotic stresses, adversely affecting plant growth and productivity. Exposure of plants to stress activates stress signalling pathways that induce biochemical and physiological changes essential for stress acclimation. Stress tolerance is governed by multiple traits, and importance of a few traits in imparting tolerance has been dem...

BACKGROUND Desiccation resistance shapes the distribution of terrestrial insects at multiple spatial scales. However, responses to drying stress have been poorly studied in aquatic groups, despite their potential role in constraining their distribution and diversification, particularly in arid and semi-arid regions. METHODS We examined desiccation resistance in adults of four congeneric water...

drought is one of the most important factors limiting growth and yield in many parts of the world. in order to evaluate the effects of drought stress on some morphological and physiological traits of two cultivars of bean, two red beans (derakhshan and goli) in four drought treatments including 25%, 50%, 75%, control 100% field capacity were studied in a factorial experiment based on complete r...
