Question

define tissue culture and their benefits

Answer 1

Tissue culture is the propagation of plants by tissue culture technique.

The benefits of tissue culture technique as follows:-

1) It provides rapid propagation of identical individuals. This technique is very productive for superior varieties.

2) It is very useful in cases where seeds are dormant. The embryo in these seeds can be cultured and micropropagated.

Answer 2

Answer:

Tissue culture is defined as a technique of growing cells, tissues, organs in an artificially prepared nutrient medium under an aseptic condition in the laboratory.

It’s advantages are:

1. Some plants, which do not multiply by seeds, can be propagated through plant tissue culture technique.
2. By the help of tissue through protoplast fusion, cell fusion, genetic engineering and hybridization technique, new improved varieties of crops can be produced within a short time period.
3. The plant produced by the application of tissue culture retain the power of disease resistance.
4. Large no. of plants can be produced in a short time.
5. Chemicals which are used in the tissue culture increase the capacity of produced plants to resist with biocidal chemicals, environment stress and competitive to survive over weed.
6. Tissue culture can be used to minimize the growing space in commercial nurseries for the maintenance of stock plants.
7. By tissue culture technique, mutation can be introduced in the cultures and resistant mutants can be selected to produce resistant varieties.
