Abstract
Seeds of cardamom (Elettaria cardamomum Maton) variety Malabar were found to exhibit dormancy due to their hard seed coat. Experiments were conducted to study the effect of various physical and chemical treatments for breaking seed dormancy. Treatment of seeds with sulphuric acid (25%) for ten minutes and absolute alcohol (80%) for 30 minutes were found to be the best amongst all the treatments in breaking seed dormancy. Scanning electron microscopy of seed coat surface revealed the presence of mucilaginous layer over the control seed and irregular shape lesions of various sizes over the seed coat of treated seeds.
