| Abstract | ||
| This study was conducted to investigate the responses of blond psyllium ) Plantago ovata Forsk.) to drought stress during the heterotrophlic seedling growth. The experiment was designed to verify the effects of six osmotic potential and two seed populations in a factorial arrangement using CRD with three replications. The drought stress levels and control included 0, -3, -6, -9, -12 and -15 bar at PEG 6000. The seed populations were collected from Golestan and Isfahan provinces. Morphological characterstics, including shoot and root length and shoot/root ratio were analyzed. The shoot length between two seed populations was significantly different (p<0.01), but the root length did not show any significant difference. The S/R ratio between two seed populations was also significantly different (p< 0.05). | ||
