The demand for high quality rice represents a major issue in rice production. The primary components of rice grain quality include appearance, eating, cooking, physico-chemical, milling and nutritional qualities. Most of these traits are complex and controlled by quantitative trait loci (QTLs), so the genetic characterization of these traits is more difficult than that of traits controlled by a...

in order to study the effect of biological and chemical fertilizers of nitrogen and phosphorus on some physiological, morphological and phenological traits of sunflower this study was carried out in eivanegharb (ilam province) in summer of 2011. treatments were arranged in split factorial based on rcbd with three replications. the main plot include 4 levels of phosphorus and nitrogen chemical f...

In the current paper we investigate whether gender aVects the encoding of leadership behavior. In three studies we found evidence that perceivers had diYculty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that ...

Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that telomere maintenance may trade off against other life history characters. We used natural variation in laboratory populations of Atlantic silv...

background: rosemary (rosmarinus officinalis l.) as a member of the lamiaceae family is a valuable aromatic and medicinal plant which is cultivated in large scale in iran. therefore, it is necessary to determine influence of factors affecting plant growth and drug metabolite production. objectives: this experiment was carried out to evaluate the effects of bio-stimulators compounds on growth an...

BACKGROUND: Soil nutrition management is an important factor, which determines the plant growth. Soil fertility is determined by the presence or absence of nutrients i.e. macro and micronutrients, which are required in optimum level for crop. OBJECTIVES: Evaluate the effect different amount of nitrogen and phosphorus fertilizers in maize field under sugarcane ...

The spatial distribution of tree juveniles in relation to light environments may reflect species differe in growth, survival, and functional traits and will shape the nature of forest regeneration. Long-term experiments are important to evaluate this issue because of the potentially very long juvenile perio trees. Here, we combine a 10-year seedling survival–growth data with the results of comm...

OBJECTIVE This experiment was conducted to investigate the effects of crude glycerin from waste vegetable oil (CGWVO) on performance, carcass traits, meat quality, and muscle chemical composition. METHODS Twenty-four crossbred (Thai Native×Anglo Nubian) uncastrated male goats (16.8± 0.46 kg body weight [BW]) were assigned to a completely randomized design and subjected to four experimental di...

OBJECTIVE The existing methods for identifying multiple rare variants underlying complex diseases in family samples are underpowered. Therefore, we aim to develop a new set-based method for an association study of dichotomous traits in family samples. METHODS We introduce a framework for testing the association of genetic variants with diseases in family samples based on a generalized linear ...

Females increase their risk of mating with heterospecifics when they prefer the traits of conspecifics that overlap with traits found in heterospecifics. Xiphophorus pygmaeus females have a strong preference for larger males, which could lead to females preferring to mate with heterospecific males; almost all sympatric X. cortezi males are larger than X. pygmaeus males. In this study, we show t...
