Spraying of which of the following phytohormone on juvenile conifers helps in hastening the maturity period, that leads to early seed production?
  1. Abscisic Acid
  2. Indole-3-butyric Acid
  3. Gibberellic Acid
  4. Zeatin

Spraying 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.
