this experiment was carried out using 200 ross 308 broiler chickens in a completely randomized design with 5 treatments and 4 replicates. the true metabolisable energy of the barley hulls were determined using cecectomized roosters.the dry matter, true metabolisable energy, ash, ether extracts, crude protein, crude fiber, ndf, adf, ca and total p content of barely hulls were: 92%, 978 kcal/kg, ...

Abstract Discovering mechanisms of plant–virus–vector interactions is fundamental to understand their ecology and evolution apply this knowledge in plant protection. To study the influence varying Barley yellow dwarf virus (BYDV) transmission efficiencies on host preference Rhopalosiphum padi (L.) clones, we performed choice experiments with two barley cultivars (BYDV susceptible cv. ‘Rubina’ B...

objective: flowering time (ft) in cereals controlled by genes that had a main factor on plant development. methods: genetic and phenotypic diversity of four flowering time genes (ft2, ft3, ft4, ppd-h1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. genotypes based on days to flowering time and molecular data were grouped into early, middle...

Different winter barley cultivars showed various levels of genetic tolerance when they were exposed to different stress conditions. Therefore, investigations of interaction among genotypes (cultivars) and environments give useful information concerning yield stability and quality in barley (Blum, 1989; Ceccarelli et al., 1998, 2000; Lalić et al., 2007, 2009). Drought conditions frequently give ...

the effects of water deficit on grain yield, yield components and the physiological char-acteristics of barley (hordeum vulgare l.) varieties were studied in a split plot design dur-ing the 1999-2000 growing season in karaj, iran. five irrigation levels [0, 25, 50, 75, and 100% crop water requirements (cwr)] and six barley varieties karoon kavir , rei-hani(drought tolerant), torkman , c-74-9 (i...

The fast and efficient recovery could be an important trait defining the efficacy of plant drought adaptation. In this work, we aimed to develop a set simple appropriate physiological proxies that used as reliable indicators predict responses validate role specific traits such root length, stomata density, residual transpiration, in tolerance barley. Eighty barley (Hordeum vulgare L.) genotypes...

Cultivation of malting barley is particularly challenging as the requirements growers, for high yield, and that brewing industry, seeking a specific quality criteria, must be met simultaneously. Furthermore, significant genotypic environmental variations in grain yield properties may occur. To investigate relationships between parameters spring barley, 2-year experiment was carried out order to...

Recently, the Q biotype of tobacco whitefly has been recognized as the most hazardous strain of Bemisia tabaci worldwide, because of its increased resistance to some insecticide groups. As an alternative control agent, we selected an Isaria javanica isolate as a candidate for the development of a mycopesticide against the Q biotype of sweet potato whitefly. To select optimal mass production med...
