What is friable callus?
Compact calluses are typically green and sturdy, while friable calluses are white to creamy yellow in color, fall apart easily and can be used to generate cell suspension cultures and somatic embryos. In maize, these two callus types are designated as type I (compact) and type II (friable).
What is callus induction?
Exogenous application of auxin and cytokinin induces callus in various plant species. Generally speaking, an intermediate ratio of auxin and cytokinin promotes callus induction, while a high ratio of auxin-to-cytokinin or cytokinin-to-auxin induces root and shoot regeneration, respectively (Skoog and Miller, 1957).
What is callus Subculturing?
Once the callus tissue is formed from the explants the callus is further transferred on to a new medium. This process of transfer is called subculturing. When subcultured regularly on agar medium callus culture will exhibit an S-phase or sigmoid pattern of growth during each passage.

What is the difference between Somaclones and somatic hybrids?
Tissue culture is an achievement in plant breeding. What is a somaclone? Describe the production of somatic hybrid….
| Somaclones | Somatic hybrids |
|---|---|
| i) Somaclones are genetically identical to the parents from which they are grown. | i) Somatic hybrids are non-identical to the parents from which they arise. |
What is the difference between clones and Somaclones?
Key difference between clones and somaclones is that clones are morphologically and genetically similar individuals develop as a result of asexual reproduction is specially mitotic cell division in somatic cells of prokaryotic organism like bacteria without fusion and formation of gametes whereas somaclones are group …
