Abstract
Seed priming is a very important operation for healthy germination and seedling growth. Though a growing body of literature, the report on seed priming on watermelon is hardly available. Thus an experiment was conducted to study the germination and seedling performance of three watermelon cultivars viz. Asian 2, Pakorea F1 and Black Red with six seed priming treatments such as hydropriming with distilled water, halopriming with 1.5N NaCl and 3% KNO3, osmopriming with 3% PEG (Polyethylene Glycol), oxidative priming with 0.1N HCl solution and control i.e. no priming. The seeds were primed overnight with the aforesaid liquids and were allowed to grow both in petridishes in dark condition within laboratory and in pot soil under natural condition in an open grill house. All three watermelon cultivars showed significant difference due to seed priming with aforesaid primers. Germination Index (GI) was found higher in Asian 2 and Black Red cultivars due to HCl priming and in Pakorea F1 due to NaCl priming, while priming with PEG and KNO3 inhibited the GI of respective cultivars. Seedling Vigor Index (SVI) was found higher in Pakorea F1 with HCl priming whereas lower in Asian 2 and Black Red cultivars with PEG priming. Both in dark (Lab) and light (open field) conditions, total seedling dry matter was found higher in Asian 2 and Black Red cultivars due to HCl priming and lower in Pakorea F1 due to PEG priming. Results showed that low concentrated (0.1N) HCl solution can be used as priming medium to enhance germination and seedling growth of watermelon seeds.
