abstract- this experiment was carried out during the growing seasons of 2010 and 2011 at the agricultural research farm of bu-ali sina university, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. experiments consisted of two sets of treatment...
In the current study, the biosynthesis of germin was determined in the organs of wheat embryos during germination. The temporal and spatial determination of germin protein was carried out by employing an anti-germin sera in gel-blot analysis. Germin was detected in the coleoptile, roots and vascular transition region of and 6-day-old germinated wheat seedlings. It was shown that the leaf tissue...
determination of cardinal temperatures during seed germination and emergence as well as the thermal time requirement for each stage is essential in crop management and modeling of plant growth and development. two experiments were conducted to predict cardinal temperatures and thermal time requirement for germination and emergence of chickpea genotypes. in the first experiment, seed germination...
The germination of three cerrado herbaceous species: Bidens gardneri, Vernonia herbacea (Asteraceae) and Psychotria barbiflora (Rubiaceae) was studied using seeds stored in cerrado soil and in refrigerator at 4°C. The field experiment was carried out at a preserved area of cerrado, the Reserva Biológica e Estação Experimental de Mogi-Guaçu, State of São Paulo, Brazil. The soil was collected in ...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
Many endangered plants such as Eryngium viviparum (Apiaceae) present a poor germination rate. This fact could be due to intrinsic and extrinsic seed variability influencing germination and dormancy of seeds. The objective of this study is to better understand the physiological mechanism of seed latency and, through artificial intelligence models, to determine the factors that stimulate germinat...
the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
Petroleum hydrocarbons as organic contaminants are among the materials that pollute the soil. These compounds and the resutant stress to plants limit selection of suitable species to be planted in hydrocarbon contaminated sites. The aim of this research was to determine the effects of petroleum compounds on germination and morphophysiological characteristics of wheatgrass (Agropyron desertorum)...
A study was carried out to test whether a single count of radicle emergence (RE test) would correlate with the storage potential seed lots cucurbit ( C. maxima × moschata ) rootstock cultivars. The RE performed by counting percentage between 26 and 100 hours germination. Seed longevity determined at 75% relative humidity 35°C over days, survival curves constructed based on normal germination pe...
apricot (prunus armeniaca), palys an important role in fruit production industry in iran. irregular set of fruit, caused by either sterility of flower organs or incompatibility has been the main problem in apricot production over the years. in this study, it has been attempted to determine these phenomena for four apricot cvs. namely ‘shahroodi’, ‘nasiri’, ‘jahangiri’ and ‘noori’ through the me...
