Question

Pollen culture produces

• A. Haploid plants where every gene can express its effect
• B. Homozygous diploid plants
• C. Abundant seeds of rare plants
• D. Abundant pollen in male sterile plants

Answer 1

The correct option is A Haploid plants where every gene can express its effect

Pollen culture is a technique of production of haploid plants by the culture of pollen grains obtained from an anther of a plant under the aseptic condition on artificial media of known composition. The technique was discovered by Guha and Maheshwari. The pollen's were obtained by squeezing the anthers after surface sterilizing with hypochlorite. The obtained pollen's were cultured on nutrient media. The pollen's develops into a callus which is treated with auxin it promotes rooting and when it is treated with cytokinin it stimulates cell maturation, differentiation and finally, promotes the development of stem. The haploid plants were developed because cytokinin stimulates cell differentiation which is caused due to the expression of genes. The expressed genes produce hormones and show its effect. For example, florigen hormone is released for flowering.

So, the correct answer is option A.
