The gas used for artificial ripening of green fruit is ?

  • A.Ethane
  • B.Ethylene
  • C.Acetylene
  • D.Carbon dioxide

Answer: B

Ethylene ripens green fruit artificially.

It is the plant's own ripening hormone, and a few parts per million in a closed chamber will start the breakdown of chlorophyll and the conversion of starch to sugar. Because it is a gas, one ripening fruit hastens the ripening of others beside it.
