Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...
In the context of intensive and sustainable agriculture, limiting soil degradation loss organic matter has become an obligation to maintain food security. The use organo-mineral fertilizer (OMF) products is innovative technology that may solve different challenges raised. This study aimed evaluate effect various formulations on Zea mays agro-physiological traits, phosphorus (P)-related paramete...
Drought stress is one the most limiting factors for crop production worldwide. The wide ecological and environmental dispersion of crop wild relatives, generates a high potential of their adaptive diversity to abiotic stresses such as drought. In this study 21 (including 10 cultivated and 11 wild barley (Hordeumvulgaressp. spontaneum))genotypes were evaluated under three soil water conditions f...
Several personality/temperament traits have been linked to health outcomes in humans and animals but underlying physiological mechanisms for these differential outcomes are minimally understood. In this paper, we compared the strength of a behavioral trait (behavioral inhibition) and an associated physiological trait (glucocorticoid production) in predicting life span. In addition, we examined ...
Many species of harmful algae transition between a motile, vegetative stage in the water column and a non-motile, resting stage in the sediments. Physiological and behavioral traits expressed during benthic-pelagic transition potentially regulate the timing, location and persistence of blooms. The roles of key physiological and behavioral traits involved in resting cell emergence and bloom form...
This research was conducted to assess the effect of drought stress on grain yield and some physiological characteristics of 28 canola cultivars. Cultivars were evaluated at two moisture environments (normal and drought stress) according to randomized complete block design. Results of analysis of variance showed that there was significant difference among canola cultivars for all measured traits...
Phenotypic correlations (rP) have frequently been observed between physiological and behavioural traits, and the nature of these associations has been shown to be modulated by a range of environmental stressors. Studies to date have examined the effects of acute stressors on physiology-behaviour interrelations, but the potential for permanent changes induced by exposure to stress during develop...
Sexually-selected exaggerated traits tend to be unusually reliable signals of individual condition, as their expression tends to be more sensitive to nutritional history and physiological circumstance than that of other phenotypes. As such, these traits are the foundation for many models of sexual selection and animal communication, such as "handicap" and "good genes" models. Exactly how expres...
A sample set of 21 rice varieties composed of 20 BRRI developed modern rice varieties and one local variety was selected to detect the genetic variation by using 13 morphological traits, 14 physiological traits and 34 SSR markers. All these three methods divide the varieties into five clusters and showed that there exist high genetic variations among the genotypes. Cluster analysis showed that ...
