It was evaluated the damage caused by Bruchus pisorum on the germination ability of pea forage cultivars. Result of damage in seeds with parasitized larva was a significant decrease of the germination by 16.4% percentage points, the length and weight of primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and 14.1%, the vigor index of primary radicle and plumule by 32.5 a...
allelopathic relationship between plant associations, could be applied in non-chemical weed management, however, those allelochemicals should not have adverse effects on arable crops. in order to evaluate allelopatic effects of barley (hordeum vulgare) on germination & growth characteristics of lentil (lens esculenta), two experiments were conducted based on compactly randomized design (crd...
Soil moisture is one of the most important determinants of plant’s seed germination, emergence and finally yield formation in arid and semi-arid zone (e.g. IRAN). In such a situation, the selection of a cultivar resistant to drought is the most important task. In this regard, a research at three levels (Farm, Greenhouse, Laboratorial) was conducted to study 10 genotypes with three improved back...

abstract in this study, we synthesized a novel template polymer by using methacrylic acid (mma) as functional monomer, ethylene glycol dimethacrylate(egdma) as cross linker, 2,2-azobisisobutyronitrile (aibn) as initiator and olanzapine as targeted molecule in the presence of chloroform and acetonitrile as solvent. the products have been characterized and confirmed by (chn)elemental analysis,...
introduction lentil is one of the major legume with protein content about 28% where is cultivated in different regions of iran, especially in arid and semi-arid regions with low or variable rainfall. in these regions abiotic stresses such as heat of the around the end of growing season, drought stress in early and late within the season and salt stress alone or together have a large negative im...
abstract in order to study the effect of environmental factors (light, temperature, salinity and drought stress, acidity and burial depth) on germination and emergence of eastern dodder (cuscuta monogyna vahl), experiments were conducted at the research laboratory of faculty of agriculture, birjand university in 2009. results showed that seeds of this parasite weed had identical germination und...
previous studies regarding teachers’ beliefs have revealed that teachers’ beliefs have influence on their classroom practices. the current study aimed to investigate the effect of teachers’ beliefs about teaching reading strategies on students’ motivation and success in reading comprehension in the context of english teaching as a foreign language in high schools of mazandaran, iran. data were ...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
