AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...

Starches were purified from barley flours milled from Waxbar, Glacier, high-amylose Glacier (HAG) and hull-less high-amylose Glacier (HHAG) cultivars. Wheat starch, maize amylopectin, maize amylose, and normal maize starch were used for comparative controls. Starches were either boiled or moisture-autoclaved (3 or 12 times) with subsequent cooling overnight, after which enzyme-resistant starch ...

Brassinosteroids (BRs) play important roles throughout plant growth and development. Despite the importance of clarifying the mechanism of BR-related growth regulation in cereal crops, BR-related cereal mutants have been identified only in rice (Oryza sativa). We previously found that semidwarf barley (Hordeum vulgare) accessions carrying the "uzu" gene, called "uzu" barley in Japan, are non-re...

in order to study the response of wheat (triticum aestivum) cv. chamran and wild barley (hordeum spontaneum) to different herbicides, a pot dose response experiment was conducted in a completely randomized design with three replication at research greenhouse of ferdowsi university of mashhad in 2008. different doses of herbicides including clodinafop propargyl, pinoxaden, sulfosulfuron, and met...

Distal half-kernels of barley (Hordeum vulgare L.), after imbibition for 1 day, produced a carboxypeptidase that was active on N-carbobenzoxy-l-phenylalanyl-l-alanine and on N-carbobenzoxy-l-phenylalanyl-l-phenylalanine. For the ensuing 2 days, activity increased linearly and thereafter increased at reduced rates. Electrofocusing of an imbibed half-kernel homogenate produced coincident peaks of...

Yomo (8) and Paleg (5) independently fouind that the induction of a-amylase in the embryo-less grain was stimulated by gibberellin. This fact was confirmed by several investigators (1, 4, 7). Recently one of the authors and his co-workers found that helminthosporol and its air-oxidation derivative, helminthosporic acid, had the same effect as gibberellin. We have investigated isozyme(s) of a-am...

irrigated barley is grown on about 50,000 hectares in the warm agro-climate zone in the south of iran. the average grain yield of barley in these areas is 2,000 kg/ha. wide adaptability and high grain yield stability are important assets for barley varieties to be grown by farmers. zahak barley cultivar was initially selected from international barley germplasm received from cymmit and based on...
