What is Tissue Culture?

UNDERSTANDING TISSUE CULTURE

Tissue culture is a technique for growing plants in a controlled environment, using small tissue samples. It enables the regeneration of whole plants from a few cells, allowing for rapid propagation and improved disease resistance.

Types of Plant Tissue Culture

ORGAN CULTURE

Involves the culture of whole organs such as roots or shoots. Organ culture maintains the architecture and organ function.

CELL AND CALLUS CULTURE

Focuses on the cultivation of individual cells or cell clusters (callus), often leading to the differentiation of plant tissues.

Micropropagation Steps

INITIATION PHASE

Selecting healthy plant tissue and sterilizing it in a culture medium.

MULTIPLICATION PHASE

Encourages rapid growth by subculturing into media rich in nutrients.

ROOTING PHASE

Inducing root formation in shoots to prepare them for soil transfer.
