Callus culture

callus culture-unspecialized cells from which whole plant is regenerated ,mass of cell.It produced when are cultured on medium .

1. CALLUS CULTURE Presented by Desika.J MSC -1 st year

2. Three stages of callus culture 1 .Induction: Cells in explant dedifferentiate and begin to divide.

3. 2.Proliferative Stage Rapid cell division

4. 3.Morphogenesis stage: Differentiation and formation of organized structures; specifically processes that lead to plant regeneration from somatic cells.

5. MORPHOLOGY and characteristics of callus Callus tissue proliferate as amorphous mass of cells having no regular shape. So it difficult to describes its external morphology. But they can be distinguished on the basis of other characteristics such as Texture , Colouration , Hormone requirements etc. On that basis , even callus tissue initiated from explants of the same plants species may show considerable variation
