Physiological seedling vigour parameters of wheat as influenced by different seed invigoration techniques

The present investigation was carried out to study the response of physiological seedling vigour parameters of wheat as influenced by different seed invigoration techniques. Seeds of wheat variety UP 2565 were treated with electro- magnetic radiation (EMR) of 100 and 200 mT for one hour, hydropriming for 12 hours and plasma treatment for 6 minutes which were tested along the untreated seeds. The results revealed that all the seed invigoration treatments improved germination and seedling vigour parameters of wheat seed. The water absorption of plasma treated seeds increased by 42.2% and 23.9% after 6 and 12 hours of imbibitions period respectively over untreated seeds. The highest germination percentage was recorded in plasma treated seeds which was at par with electro- magnetic radiation (EMR) for 200 mT. The plasma treated seeds also emerged earlier than control and also took less time to emerge than rest of the treatment including untreated seeds.
