Which of the following is not an influence of auxins?
1 Apical dominance
2 Parthenocarpy
3 Phototropism
4 Fruit ripening
Explanation:
Auxins inhibit the growth of axillary buds and promote apical dominance. It induces parthenocarpic development of fruits and such fruits are seedless and auxin is also responsible for phototropism and geotropisms. Ripening and maturity of fruits are related to ethylene.
