Question

Parthenocarpy can be induced by

• A. Treating the stigma by lanolin
• B. ABA and MH treatment
• C. Exposure to I.R rays
• D. Auxin and GA treatment

Answer 1

The correct option is D Auxin and GA treatment

Parthenocarpy is the natural or artificially induced production of fruit without fertilization of ovules. The fruit is therefore seedless. When sprayed on flowers, any of the plant hormones gibberellin, auxin and cytokinin can often stimulate the development of parthenocarpic fruit. This is termed artificial parthenocarpy. Plant hormones are seldom used commercially to produce parthenocarpic fruit.
