Isabgol (Plantago ovata Forsk) seed germination and emergence as affected by environmental factors and planting depth

Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...
