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...

in order to compare morphophysiological traits between new and old cultivars of barley (hordeum vulgare l.) a greenhouse experiment was conducted in greenhouse condition in faculty of agriculture, ferdowsi university of mashhad in spring and summer 2011.the type of experiment was a completely randomized design with eight treatments (nosrat , youssof , fagr30 , nick) and four old cultivars inclu...

schizaphis graminum (rondani) (hem.: aphididae) is one of the seriously injurious pestsof cereals particularly of barley. the population of the pest has beenon the increase in recentyears. besides chemical control, another practically suitable method of controlling the pest isthe use of resistant barley genotypes. in this research, 47 advanced lines along with 13 cultivarswere screened in their...

this study was carried out to determine regression equations for prediction of apparent metabolizable energy corrected by nitrogen (amen) using 11 barley cultivar (valfajr, karon, bahman, aras, dasht, afzal, zarjo, kavir, reihani, makui and yousef) the seeds obtain from alborz province, iran. all of the cultivar were analyzed based on proximate analysis, starch, ndf and adf. result showed that ...
