Question

Identify the incorrect statement related to the physiological roles of auxins

• A. Auxins help to promote fruit and leaf drop at early stages but prevents the abscission of older mature leaves and fruits
• B. Auxins promote flowering in pineapples
• C. Auxins induce parthenocarpy
• D. High auxin concentration promote more female flower formation

Answer 1

The correct option is A Auxins help to promote fruit and leaf drop at early stages but prevents the abscission of older mature leaves and fruits

Auxins help to initiate rooting in stem cuttings, an application widely used for plant propagation. Auxins promote flowering e.g. in pineapples. They help to prevent fruit and leaf drop at early stages but promote the abscission of older mature leaves and fruits. Auxins also induce parthenocarpy, e.g., in tomatoes. They are widely used as herbicides and promote apical dominance.
