A hydroponic experiment was carried out to compare root anatomy and hydraulic conductivity of four barley cultivars including Valfajr, Karoon, Afzal and Zarjo under salt stress conditions. The results showed that under salt stress, the minimum diameter of vessels was observed in the peripheral metaxylem of seminal roots of Valfajr cultivar and in adventitious roots; Karoon with 19±3 µm had maxi...

â  abstract â  in this study by data of synoptic stations in karoon basin, the intensive showers with 1,2,6 and 9 hour duration have been extracted and the precipitation time regime has been evaluated by ranking method and non dimensional accumulation curve. in ranking method, first the showers of each time base have been divided to smaller periods and on this basis different periods of showers...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on forage and grain quality of barley (Karoon x Kavir cultivar) was studied in Experimental Farm of College of Agronomy and Animal Sciences, University of Tehran during 2006-2007 growing seasons. Three phosphorus fertilizer levels of 0 (control), 30 and 60 kg ha were al...
