Which one of the following synthetic growth regulators is used to promote synchronised flowering in pineapple?
- A Benzyl aminopurine
- B Phyenylmercuric acetate
- C Indolebutyric acid
- D 2-chloroethylphosphonic acid
Answer & Solution
Correct Answer
(D) 2-chloroethylphosphonic acid
Step-by-step Solution
Detailed explanation
(D) 2-chloroethylphosphonic acid,
2-Chloroethylphosphonic acid, commonly known as Ethrel, is used to promote synchronized flowering in pineapples. It acts as an ethylene-releasing compound, which induces flowering.
