✦ Synopsis

Plants were regenerated from cotyledon and hypocotyl explants of watermelon (Citrullus vulgaris). The explants were cultured on a Murashige and Skoog's basal nutrient medium supplemented with auxin, cytokinin and auxin-cytokinin combinations. Green healthy nodular and compact callus was obtained in medium containing naphthalene acetic acid and benzylaminopurine. Shoot differentiation and root differentiation from the cotyledon and hypocotyl after callus formation in different media containing benzylaminopurine or naphthalene acetic acid, respectively. Shoot formation required benzylaminopurine. Kinetin proved ineffective in inducing shoot buds or shoots. Root differentiation occurred in a medium containing naphthalene acetic acid or indole acetic acid. There was a greater proliferation of roots on medium supplemented with naphthalene acetic acid. The regenerated shoots developed roots when transferred to medium containing naphthalene acetic acid and complete plantlets could be transferred to soil for further growth.
