Abstract
This study was carried out to investigate the effects of induced wet-injury conditions on barley seedling growth. Barley seedlings at the three leaf stage were grown in culture solutions with various combinations of dissolved oxygen (DO), nutrients and citric acid (CA) concentrations. Seedling growth was reduced by hypoxia. Root length and root fresh weight were most severely reduced under 1 ppm DO. Shoot growth was slightly reduced but not root growth under low nutrient condition. Seedling growth was reduced by CA in a concentration-dependant manner, Response of seedling growth was efficiently differentiated in a solution containing 1 ppm DO, one tenth of the normal P, K and Mg concentration and 3 mM CA. Under this induced wet-injury condition, overall seedling growth of 6 cultivars was reduced by 11 to 19% compared to the control condition. The results suggest that the induced wet-injury condition can be used for the screening of resistant genotypes at the seedling stage.
