Domestication and artificial selection have reduced the level of genetic variation in barley. Inter-specific hybridization is one of the most valuable ways to restore at least part of the lost variation. This study aimed to investigate genetic diversity and screening barley lines which possessed the desired traits, as well as drought tolerance, within two F3 populations derived by crossing a cu...

abstract: salicylic acid is a phytohormone with phenolic nature which has been proved its role in increasing plant resistance to biotic and abiotic stress in several studies. this study was performed in order to investigation of interaction between 0, 0.5 and 1.5 mm concentrations of salicylic acid, as a seed pretreatment and different levels of drought stress (100, 75, 50 and 25 percent of fie...

In this study, a method for non-invasive estimation of stress on the heart wall in  the diastole phase is presented using ultrasound echocardiography and tissue Doppler  imaging. The aim of this study was to evaluate the stress on the heart wall as a  pre-diagnosis  to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...

This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...

Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...
