Step-by-step solution
Gibberellins produce a wide range of physiological responses in different plants: Cabbage: Gibberellins promote bolting (internode elongation just prior to flowering) in beet, cabbages and many plants with rosette habit. Sugarcane: Spraying sugarcane crop with gibberellins increases the length of the stem, thus increasing the yield. Juvenile conifers: Spraying juvenile conifers with GAs hastens the maturity period, thus leading to early seed production. Apple: GAs are used to cause fruits like apple to elongate and
