Prijava / prijava
Callus cultures have been established from root explants of aseptically-grown Podophyllum hexandrum seedlings. A fully defined medium based on Gamborg's B5 salts supplemented with 2/4-dichlorophenoxyacetic acid, gibberellic acid and 6-benzylaminopurine was effective for both initiation and sustained
