Effects of Organic and Inorganic Seed Treatment and Packing Materials on Seed Quality of Bittergourd (Momordica charantia L.) during Storage

摘要

The cultivated species Momordica charantia L. is the familiar bitter gourd of India. In the present study, freshly harvested bitter gourd seeds were treated with captan (2g/kg), neem leaf powder (5g/kg), pongamia leaf powder (5g/kg), neem oil (5ml/kg), castor oil (5ml/kg) and calcium oxychloride (5g/kg) and packed in polythene bag (700 gauge), aluminium pouch and cloth bag and stored for 10 months under ambient condition at KRC College of Horticultural College Arabhavi, District Belgaum of KarnatakaState. The results revealed that the seeds treated with captan recorded significantly higher germination percentage (94.11), seedling dry weight (121.6 mg) and vigour index (3391) at the end of 10 months of storage and the lowest electrical conductivityof seed leachate (0.344 dSm~(-1)) was recorded with captan seed treatment at the end of 10 months of storage and it was on par with calcium oxychloride, pongamia leaf power and neem leaf powder. Seeds packed in different containers and interaction effects showed no significant.
