Gibberellin Effects on Plant Maturity — NEET Biology
✅ Asked in NEET 2023Spraying juvenile conifers with GAs hastens the maturity period, thus leading to early seed production. Gibberellins also promotes bolting (internode elongation just prior to flowering) in beet, cabbages and many plants with rosette habit.
NTA tests how gibberellins (GAs) accelerate maturation in juvenile plants by promoting early flowering and seed production, particularly in conifers and rosette plants. Students often confuse gibberellins with auxins or ethylene, forgetting that GAs specifically hasten developmental processes rather than just promoting growth. Another common mistake is thinking GAs work universally on all plants at any age—actually, they're most effective on young, juvenile plants. Remember: gibberellins trigger bolting (stem elongation before flowering) and reduce juvenility period, enabling earlier reproductive maturity and seed set. This mechanism is agriculturally important and directly testable for plant hormone functions.
Spraying of which of the following phytohormones on juvenile conifers helps hastening the maturity period, that leads to early seed production? (NEET 2023)
