The arabinogalactan proteins (AGPs) are involved in a range of plant processes, including cell differentiation and expansion. Here, barley root hair mutants and their wild-type parent cultivars were used, as a model system, to reveal the role of AGPs in root hair development. The treatment of roots with different concentrations of βGlcY (a reagent which binds to all classes of AGPs) inhibited o...

livestock industry (CGC, 1996). Barley is also used for malt production and a small amount is used for human Understanding the phenological development of barley (Hordeum food. Understanding the development of barley in this vulgare L.) grown under field conditions in its major growing area in the northern Great Plains, the Canadian province of Alberta, is environment is crucial to continued ad...

Knowledge of the physiological responses of barley, Hordeum vulgare L., to the Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae) is critical to understanding the defense response of barley to aphid injury and identifying resistance mechanisms. This study documented the impact of D. noxia feeding on resistant (‘Sidney’) and susceptible (‘Otis’) barley through chlorophyll fl...

Barley is integrated with other crops to inhibit weed growth, through allelopathic interactions. Effects of barley on growth of other crops, weeds and autotoxicity among cultivars result primarily from allelopathy mediated by allelochemicals released from plant components and/or exuded from living roots. A limited number of allelochemicals are identified that contributes to allelopathic effecti...

in order to compare photosynthetic features of triticale, bread wheat, and barley under water deficit conditions, this experiment was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, and a new variety of barley were compared under well watered (ψsoil= -3 bars) and soil water deficit (ψsoil= -12 bars) conditions in a randomized compl...

The detrimental drought effects could be listed as the loss in dry weight and silicon is known to enhance crop tolerance to drought by increasing seedling growth and hydraulic conductivity. To investigate the effects of silicon priming (0, 1 and 2 mM as sodium silicate), on seedling growth and root anatomy of three barley cultivars (Khatam, Rihane, and Nimrooz) a laboratory experiment was condu...
