Following are the important function of ethylene:

Growth: Ethylene stimulates horizontal growth and the swelling of the axis. It inhibits the growth in the longitudinal direction.

Gravity : It reduces the sensitivity to gravity. The stems become positively geotropic and the leaves and flowers undergo drooping.

Senescence: It speeds up the senescence of flowers and leaves.

Abscission: Ethylene stimulates the abscission of flowers, leaves, fruits and other parts of the plant. It helps in the formation of hydrolases.

Apical Dominance: It prolongs dormancy of lateral buds and promotes apical dominance.

Breaking Dormancy: It breaks the dormancy of seeds, buds and storage organs.

Ripening of Fruit: Ethylene induces artificial ripening of climacteric fruits such as banana, mango, apple, etc.
