Which of the following is not a consequence of using ethephon?

Options

  1. AThinning of cotton
  2. BHastened fruit ripening in tomatoes
  3. CAccelerated abscission
  4. DPromotion of male flowers in cucumbers

Correct answer

D. Promotion of male flowers in cucumbers

Step-by-step solution

The most widely used compound as source of ethylene is ethephon. Ethephon in an aqueous solution is readily absorbed and transported within the plant and releases ethylene slowly. Ethephon hastens fruit ripening in tomatoes and apples and accelerates abscission in flowers and fruits (thinning of cotton, cherry, walnut). It promotes female flowers in cucumbers thereby increasing the yield.
