Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...

CONTEXT Iatrogenic obesity caused by atypical antipsychotics increases the rate of death from all causes. Olanzapine is a commonly prescribed atypical antipsychotic medication that frequently causes weight gain. To our knowledge, the neural correlates of this weight gain have not been adequately studied in humans. OBJECTIVE To test the hypothesis that olanzapine treatment disrupts the neural ac...

Ant-aphid interactions may affect host plants in several ways, however, most studies measure only the amount of fruit and seed produced, and do not test seed viability. Therefore, the aim of this study was to assess the effects of the presence of ant-aphid interactions upon host plant productivity and seed viability in two different contexts: isolated and within an arthropod community. For this...

snoring can occur alone or it may be the presenting feature of obstructive sleep apnea and other common chronic conditions. in our study, we aimed to estimate the prevalence and correlates of snoring in adolescent students in tehran, iran. a cross-sectional study was designed and students were selected from 20 secondary and high schools, in 5 different zones in tehran in order to have a represe...

in order to study the effect of different redroot pigweed (amaranthus retroflexus) density on yield, yield components of soybean cultivar and determining competitive cultivar, a field experiment was carried out at mazandaran agricultural research station 2006. experiment was set up at a randomized complete block design with five rates of pigweed (0, 4, 8, 12 and 16 plant per square meter) and t...

drought is a major limiting factor for agricultural production in most parts of the world and landraces areimportant genetic resources for crop improvement in dry areas. during the 2007-2008 cropping season, 23 chickpea (cicer arietinum l.) genotypes consisting of 21 kabuli chickpea landraces provided by the national plant gene bank of iran and two known commercial varieties (hashem and arman) ...

genetic diversity in bean collection can be used in breeding program for selection of genotype with desirable agronomic traits. fifty two accessions of common bean (phaseolus vulgaris) has been evaluated for genetic diversity of agronomic traits, grain quality and determination of association between grain yield and some morphological traits at research farm of national plant gene bank of iran,...
