Abstract
The present study successed in obtaining callus from embedding cell suspension of Glycine max in agar using Multiple Drop Array (MDA) technique.Results indicate that liquid Murashige and Skoog (MS) medium supplemented with 0.1 mg/L NAA and 2.0 mg/L BA promot divisions of cell and colonies formation.Moreover,electro-treatment of those cell suspension before culture enhanced division of cells and increased colonies formation. Interestingly, the results indicate that mixing certain quantity of Ri-plasmid with cell suspension also stimulate formation of cellular colonies. Generally all these treatments led to the formation of small pieces of callus in agar drops, These fragments of callus continued its growth on subculture medium.
