How does ethephon increases the yield of cucumber?

Options

  1. Apromote senescence
  2. Bpromotes female flowers
  3. Cpromotes male flowers
  4. Dboth A and B

Correct answer

B. promotes female flowers

Step-by-step solution

Ethylene is one of the plant growth regulator and it is in gaseous form. It promotes senescence and abscission of plant organs. Mainly observed in leaf and flower. Ethephon is a the most widely used source of ethylene. Its aqueous solution is easily absorbed and transported within the plant. It releases ethylene slowly within the plant useful in fruit ripening. Also, it is useful in increasing yield of cucumber by promoting female flower.
