Question

In the mechanism of parthenocarpy, the hormones auxins (IAA), gibberellins, or cytokinins function by:

Options

• Promoting pollen tube growth

• Stimulating ovule development

• Mimicking the post-fertilisation hormonal environment

• Preventing cell division in the ovary

Answer 1

In the mechanism of parthenocarpy, auxins (IAA), gibberellins, or cytokinins mimic the post-fertilisation hormonal environment. These hormones trick the ovary into believing fertilisation has occurred, triggering fruit development without actual fertilisation.
