Effect of sodium nitroprusside (SNP), a donor of nitric oxide (NO) was examined in two wheat (Triticum aestivum L.) cultivars, C 306 (heat tolerant) and PBW 550 (comparatively heat susceptible) to study the extent of oxidative injury and activities of antioxidant enzyme in relation to high temperature (HT) stress. HT stress resulted in a marked decrease in membrane thermostability (MTS) and 2, ...
Basically, the most important limiting factor in plant growth is the lack of water. More lands in Iran are located in arid and semi-arid region and so identifying of ghenotype that can produce acceptable yield under drought conditions is essential. In order to identification of drought stress tolerant varieties, 20 wheat cultivars were evaluated at three stress levels (control, -0.6 and -1.2 MP...
Understanding the reaction form and biochemical response of wheat cultivars about the salinity stress can help to better understand the defense mechanisms and identify the indicators and biomarkers of tolerance screening for salinity stress in this strategic plant and other field crop. For this purpose, biochemical traits related to salinity tolerance of wheat cultivars were evaluated as a f...
Line Yesevi-93 (cultivar Abidar) was first introduced to Dryland Agricultural Research Institute (DARI) through the International Winter Preliminary Barley Yield Trials (IWPBYT) in 1994. It was selected as one the most high yielding lines based on observational and statistical trails (Regional Barley Yield Trials) carried out in different locations during 1997-2000. The average yield of Abidar...
Identification and characterization of tolerant and susceptible cultivars of crop plants to cold stress is important. In this regard, in present research electrolyte leakage and Total Soluble Sugar (TSS) contents in the leaf and bark tissues in ten olive cultivars, namely, Zard, Mari, Fadak87-1, Fadak87-5, Fadak86, Fadak77, Arbequina, Mission, Blady and Coratina were measured to assess their re...
Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
Environmental stress, especially drought stress, can play an important role in the reduction of the plant growth stage, specifically duringgermination in arid and semi arid regions in Iran.. In order to study the effects of drought stress on germination indices in wheat cultivars, an experiment was conducted in factorial form, using a completely randomized design of four replications. In this e...
Cotton (Gossypium hirsutum L.) production in Oklahoma has more than tripled the last ten years. This increase cotton acreage Oklahoma, a region that traditionally produces winter wheat, led to increased incidences of 2,4 D contamination sprayers are used spray crops. is extremely sensitive D, with losses yield and ultimately profit producer cases drift or tank carryover. In this study, six cult...
a principal obstacle facing intensive pear orchard establishment in iran is the absence of appropriate dwarfing or semi-dwarfing rootstocks, compatible with commercial cultivars, as well as showing adaptability with alkaline soils. this research aimed at an evaluation of the hawthorn seedlings (crataegus sp.) as a potential dwarfing rootstock for pear and a comparison of its dwarfing effects wi...
