Question

In plant tissue culture, the callus tissues can be regenerated into complete plantlets primarily by altering the concentration of

• A. sugars
• B. vitamins
• C. amino acids
• D. hormones

Answer 1

The correct option is D hormones

In plant tissue culture, the callus tissues can be regenerated into complete plantlets primarily by altering the concentration of hormones. In fact, shoot and root regenerations are generally controlled by auxin-cytokinin balance. Usually, an excess of auxins promotes root regeneration while cytokinins promote shoot regeneration.

So, the correct option is 'Hormones'.
