NEET · Biology · STD 11 - 13. Plant growth and development
The Avena curvature is used for bioassay of
- A \(IAA\)
- B ethylene
- C \(ABA\)
- D \(GA_3\).
Answer & Solution
Correct Answer
(A) \(IAA\)
Step-by-step Solution
Detailed explanation
(a) : Avena curvature test is a test based on the experiments of Went \((1928)\) which can measure auxin upto \(300\ mg/litre\). Indole \(3\) - Acetic Acid \((IAA)\) is a universal natural auxin and Avena curvature test may serve as an accurate bioassay for this plant hormone.
