in order to deliberate correlation coefficient between grain yield and yield components among 31 cowpea genotypes under normal irrigation (non-stress) and drought stress (water withholidng after flowering stage until maturity) an experiment was performed in a randomized complete block design (rcbd) with three replications at research field of university of tehran located at karaj during 2011-20...

A functional polymorphism in the regulatory region of the serotonin transporter gene (5-HTTLPR) is considered to be a plausible candidate gene for anxiety-related personality traits and for alcoholism. Empirical support for the association between 5-HTTLPR and psychological traits has been somewhat inconsistent; however, observations of the functional dominance of the low-activity s-allele over...

This paper reviews the utility and availability of biological and ecological traits for marine species so as to prioritise the development of a world database on marine species traits. In addition, the 'status' of species for conservation, that is, whether they are introduced or invasive, of fishery or aquaculture interest, harmful, or used as an ecological indicator, were reviewed because thes...

drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...

in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a  population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...
