Advertisements
उत्तर
Applications of tissue culture:
- Micropropagation for rapid multiplication of plants.
- Rapid clonal propagation – an explant is used to produce numerous plants of same genotype,
- From somaclonal variation, a number of useful varieties have been produced, e.g., Higher shelf life tomato,
- Virus-free plants by using meristem culture,
- Embryo which normally do not survive inside the seeds can be grown in tissue culture. Embryo rescue useful in interspecific hybridisation.
