What effect does ethylene have on plant organs such as leaves and flowers?

Options

  1. APromotes growth
  2. BEnhances photosynthesis
  3. CPromotes senescence and abscission
  4. DInhibits growth

Correct answer

C. Promotes senescence and abscission

Step-by-step solution

Ethephon hastens fruit ripening in tomatoes and apples and accelerates abscission in flowers and fruits (thinning of cotton, cherry, walnut). Ethylene is used to initiate flowering and for synchronising fruit-set in pineapples. Ethylene is highly effective in fruit ripening. It enhances the respiration rate during ripening of the fruits.
