1. Inhibitory effect on growth :

Ethylene inhibits elongation of stem and roots and causes swelling of plant parts.



2. Flowering :

Ethylene retards flowering in most plants but also increases flowering in some plants.




3. Sex modifications :

Treatment of plants with ethylene increases the number of female flowers and fruits in cucumber.




4. Tropic responses :

Ethylene is considered as responsible for positive geotropic bending of roots.




5. Suppression of bud growth :

Ethylene inhibits the growth of lateral buds and thus causes apical dominance.





6. Fruit growth and ripening :

Ethylene stimulates the growth of fruits in some plants. It is considered responsible for the changes that occur during the ripening of fruits.





7. Root initiation :

Ethylene stimulates rooting of cuttings, initiation of lateral roots and growth of root hair.




8. Senescence :

Ethylene promotes the yellowing and senescence of leaves. It also induces flower fading in pollinated orchids.



9. Dormancy :

Ethylene is responsible for breaking the dormancy of buds and seeds.
