Plant Tissue Culture PPT

Application of Plant Tissue Culture-The most important challenge in a developing country is food for its growing population. The arable land area is fixed. Some means has to be there to increase the productivity.

Plant tissue culture technique offers an excellent opportunity for mass propagation of plants in laboratory test tubes, which are transferred to the field. Besides crop plants, the technique is also applied to regenerate saplings for plantation and regeneration of dwindled forests. Some rare and nearly extinct plant species can be rescued and propagated by this technique.

Embryos produced by incompatible crosses also are rescued, seed dormancy is overcome, life cycle is shortened and much more.

This technique is amalgamated with genetic engineering to regenerate plants with novel characters and combine two or more beneficial characters into a single plant. Things, once seemed impossible, have been made possible.

In this section, we shall discuss about four elementary applications of this technique, namely,

1. micro-propagation
2. organogenesis
3. somatic embryogenesi
4. protoplast culture and fusion.
