in order to investigate rice competition ability against weeds in direct-seeding and transplanting systems afield experiment was conducted at mahmud abad region of mazandaran province on 2011 growing season. experimental treatments were studied in a split plot factorial design based on randomized complete blocks with three replicates. direct-seeding and transplanting of rice in wet seedbed were...

This study aimed to investigate the relationship between morphophysiological and phenology traits with grain yield to determine the best indices of direct and indirect selection in the field of genetic improvement of aerobic rice grain yield in Khuzestan province with 12 aerobic rice genotypes. The traits such as include the grain yield as the dependent variable and total dry matter, panicle we...

Data from the birth weight (BW), the average daily gain from birth to weaning (ADG) and the weaning weight (WW) of 1182, 1099 and 1099 lambs were respectively collected and applied to estimate the maternal effects on heritabilities as well as on the determination of the environmental factors. The data were collected from Shahrbabak Sheep Breeding Research Station within five year, from 1993 to ...

In general, genetic selection is applied after first calving to traits that manifest themselves during the animal's productive life, mostly during the early part of productive life. This selection policy has had undesirable correlated responses in other economically important traits, such as health and fertility, and may also have had an effect on the growth of animals both during productive li...

Objective: The aim of this study was to investigate prediction of suicide ideation based on early maladaptive schemas and the Big-Five personality traits in a sample of Iranian late adolescents.  Methods: 315 high school students (160 female, 155 male) were recruited by multi-stage cluster sampling method from Shiraz city. Participants completed NEO Five-Factor Inventory, Schema Questionn...

The reasons why some plant species were selected as crops and others were abandoned during the Neolithic emergence of agriculture are poorly understood. We tested the hypothesis that the traits of Fertile Crescent crop progenitors were advantageous in the fertile, disturbed habitats surrounding early settlements and in cultivated fields. We screened functional traits related to competition and ...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Woody hemiepiphytic species (Hs) are important components of tropical rain forests, and they have been hypothesized to differ from non-hemiepiphytic tree species (NHs) in adaptations relating to water relations and carbon economy; but few studies have been conducted comparing ecophysiological traits between the two growth forms especially in an evolutionary context. Using common-garden plants o...
