Question

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

• A. Sugars
• B. Vitamins
• C. Amino acids
• D. Hormones

Answer 1

The correct option is D Hormones

Plant hormones are added to nutrient media to regulate plant growth. These hormones work independently or together to influence plant growth. Maintaining hormone balance i.e. maintaining the relative concentrations of hormones in the nutrient medium is of utmost importance rather than concentration of one single hormone, since hormones have collective effect on plant growth.
