Plant Growth Regulators - PGRs Function A. Auxins 1. Promote parthenocarpy in tomatoes. B. Gibberellins 2. Promote root hair formation. C. Cytokinins 3. Promote lateral shoot growth and delay leaf senescence. D. Ethylene 4. Induce parthenocarpy and delay fruit senescence. E. Abscisic acid (ABA. 5. Acts as a stress hormone by inducing stomatal closure.
Options
- AA - 1, B - 4, C - 3, D - 2, E - 5
- BA - 1, B - 4, C - 2, D - 3, E - 5
- CA - 4, B - 1, C - 3, D - 2, E - 5
- DA - 2, B - 4, C - 3, D - 1, E - 5
Correct answer
A. A - 1, B - 4, C - 3, D - 2, E - 5
Step-by-step solution
A - 1: Auxins promote parthenocarpy (development of fruit without fertilization) in tomatoes. B - 4: Gibberellins induce parthenocarpy and delay fruit senescence. C - 3: Cytokinins promote lateral shoot growth and delay leaf senescence. D - 2: Ethylene promotes root hair formation and helps in increasing the absorption surface. E - 5: Abscisic acid (ABA. acts as a stress hormone by inducing stomatal closure to reduce water loss.
