Question

Juvenile conifers can be induced to produce seeds earlier than usual by applying which plant hormone?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C. Gibberellins
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant hormone effects on conifer development
 **Related Topics**: Plant physiology, phytohormones, conifer reproduction
 **Prerequisites**: Basic understanding of plant hormones and their functions.
## SOLUTION PATHWAY
**Given Information**:
  A question about inducing early seed production in juvenile conifers using a plant hormone.
  Four options: Abscisic acid, Ethylene, Gibberellins, Cytokinins.
**Method & Steps**:
 1. Identify the phytohormone known for its role in promoting growth and development, particularly stem elongation and flowering.
  Reasoning: Gibberellins are known to stimulate stem elongation and flowering in many plants, including conifers.  This would lead to earlier maturity and seed production.
  Formula/Rule: None directly applicable.
 2. Eliminate options based on their known primary functions.
  Working: Abscisic acid inhibits growth and promotes dormancy. Ethylene is associated with fruit ripening and senescence. Cytokinins primarily promote cell division and differentiation.
  Key Point: The question specifically seeks a hormone that accelerates seed production, a known effect of gibberellins.
 3. Conclude based on the known effects of Gibberellins.
  Result: Gibberellins are the most likely answer.
  Verification: Research confirms that gibberellins are used to induce early flowering and seed production in conifers.
 ## OPTION ANALYSIS
A :x: Abscisic acid inhibits growth and promotes dormancy, opposite to the desired effect.
B :x: Ethylene is associated with fruit ripening and senescence, not the promotion of early seed production in conifers.
C ✓: Gibberellins are known to promote growth, flowering, and seed production, fitting the question's description.
D :x: Cytokinins mainly affect cell division and differentiation, not directly inducing early seed production.
 ## LEARNING AIDS
 **Common Mistakes**: Confusing the roles of different plant hormones, especially ABA and Gibberellins.
  1. Mistaking Abscisic Acid's role: ABA inhibits growth; Gibberellins promote it.
  How to avoid: Carefully consider the effect each hormone has on plant growth and development.
 **Quick Tips**: Remember Gibberellins' association with stem elongation and flowering, which leads to early seed production.
