Plant regeneration in vitro from leaf tissues derived from cultured immature embryos of Zea mays L.

Maize (Zea mays L.) A188 calluses derived from leaf tissues of in vitro grown seedlings were initiated and maintained on Murashige and Skoog medium supplemented with 2 mg/1 2,4-dichlorophenoxyacetic acid (2,4-D). The calluses produced green leafy structures and subsequently plantlets upon transfer to N6 medium containing 2 mg/1 2,4-D and 0.1 mg/1 zeatin. An embryo-like structure with a green prominent coleoptile and a scutellum-like body was also obtained.
