in order to evaluation the effect of zeolite application and selenium spraying on water relations traits and antioxidant enzymes in medicinal pumpkin (cucurbita pepo l.) at water deficit stress conditions, an experiment was conducted in factorial based on randomized complete block design with three replications during 2010 in takestan, iran. the three levels of irrigation factor include normal ...
Drought stress is one of the most important environmental stresses that have limited the production of wheat, especially in arid and semi-arid regions of the world. To recognize drought tolerant rain-fed wheat genotypes and to determine the best tolerance/susceptibility indices, a study was conducted at the Agricultural Research Station of Miandoab for two cropping years (2013-15). The experime...
Regarding the insufficient water resources, developing of cultivars with high tolerance to water deficit can be very effective to optimize water consumption. To identify maize hybrids with higher tolerance to water deficit, 52 single cross hybrids were field evaluated according to a randomized complete block design with three replications in each irrigation regime. The hybrids were produced thr...
manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. myc2 gene encodes a key stress-related transcription factor involved in jasmonate (ja) and abscisic acid (aba) signaling pathways in arabidopsis. brassica napus, as a globally important oilseed crop, is a close relative of arabidopsis. in the present study...
For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...
To evaluate the effect of water-deficit stress on the yield, antioxidant activity, and physiological traits of four Iranian melon genotypes (“Khatooni,” “Suski-Sabz,” “Zarde-Tabriz,” and “Shiari”), an experiment was conducted. The irrigation levels were: (1) control (100%ETc); (2) deficit irrigation 66% (66%ETc); and (3) deficit irrigation 33% (33%ETc). The results showed that the yield and rel...
One of the most important types of water erosion, is massive erosion. Soils with fine particles (especially silt particles) have little stability against erosion, because they have more water holding capacity and thus increase the saturation moisture and the likelihood of this type of erosion. So In this study, to investigate the relationship between particle size of silt, with behavior and rhe...
sensivity of seed germination stage to saline soil is the main obstacle to proper field establishment of sugar beet crop. in previous studies different tissues of sugar beet showed high tolerance to salt stress by of increasing sodium chloride levels in in vitro condition. an experiment was by to study the response of sugar beet zygotic embryos to salt stress in in vitro conditions. sterile per...
drought stress is the main limiting factor in the arid and semi-arid region of the world. this research was conducted to evaluate drought tolerance in different accessions of sainfoin for yield, morphological and agronomic traits in 2010. twenty one accessions (landraces and varieties) were evaluated in two environments including drought stress and non-stress conditions for four harvests accord...
