Question

Which of the following plant hormones is correctly matched with its function?

• A. Auxin - development of seedless fruit
• B. Cytokinin - promotes seed dormancy
• C. Abscisic acid - promotes seed dormancy
• D. Both A and C

Answer 1

Answer: (D)

Both A and C

• Seedless watermelon plants are grown from seeds. The seeds are produced by crossing a diploid parent with a tetraploid parent to produce triploid seeds. When sprayed on flowers, any of the plant hormones gibberellin, auxin and cytokinin could stimulate the development of parthenocarpic fruit.
• Abscisic acid inhibits germination of mature Arabidopsis seeds by limiting the availability of energy and nutrients. The addition of abscisic acid (ABA) to mature non-dormant seeds inhibits their germination

So, the correct answer is 'Both A and C'.
