Across diverse taxa, morphological traits mediate social interactions and mate selection. Physiological constraints on signal elaboration have been widely documented, but the potential for trait display to influence physiological state remains poorly understood. We tested for the presence of causal links between ventral plumage colour-a trait known to covary with reproductive performance-and ph...

in order to study the phenological and morphological characteristics, comparison of yield and yield components, correlation between traits and determination of the parameters affecting seed yield, a field experiment was carried out at the research farm of shahrekord university in 2007. ten lentil genotypes were compared by a randomized complete block design with three replications. the analysis...

genetic diversity of 22 morphotypes of diploid wheat (t. urartu) was investigated using morphological traits and rapd markers. morphological characterizations were carried out based on 17 traits and statistical parameters of dispersion and diversity of agronomic traits were calculated. statistical analysis showed significant differences for all characters among morphotypes. dendrograms were gen...

in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...

Plants plastically change their morphological and physiological traits in response to environmental changes, which are accompanied by changes in endogenous levels of phytohormones. Although roles of phytohormones in various aspects of plant growth and development were elucidated, their importance in the regulation of biomass allocation was not fully investigated. This study aimed to determine c...

to evaluate morphological markers linked with drought stress resistance for screening almond genotypes in the breeding programs the effect of drought stress was studied on six nominated almond genotypes seedlings. the six pre-selected water stress mimposed almond genotypes included: homozygote sweet (butte from university of california), heterozygote sweet (shahrood12, shahrood18, shahrood21 an...
