A hormone that initiates flowering and synchronising fruit set in pineapples is ______.

Options

  1. AEthylene
  2. BAbscissic Acid
  3. CAuxins
  4. DGibberellins

Correct answer

A. Ethylene

Step-by-step solution

Ethylene is a gaseous plant growth regulator that is highly effective in fruit ripening. It initiates flowering and is responsible for synchronising fruit-set in pineapples. It also induces flowering in mango.
