One hormone hastens maturity period in juvenile conifers,a second hormone controls xylem differentiation, while the third increases the tolerance of plants to various stresses. They are respectively
- A Gibberellin, Auxin, Cytokinin
- B Auxin, Gibberellin, Cytokinin
- C Gibberellin, Auxin, ABA
- D Auxin, Gibberellin, ABA
Answer & Solution
Correct Answer
(C) Gibberellin, Auxin, ABA
Step-by-step Solution
Detailed explanation
(C) Gibberellin, Auxin, ABA,
Auxin controls xylem differentiation. Abscisic acid (ABA) increases the tolerance of plants to various kinds of stress therefore, also known as stress hormone.
Auxin controls xylem differentiation. Abscisic acid (ABA) increases the tolerance of plants to various kinds of stress therefore, also known as stress hormone.
