What is function of ethylene.

Ethylene is synthesized in ripening fruits, fruits, flowers, leaves and even roots and acts as a natural plant growth hormone.

Physiological effects of Ethylene:

• It shows inhibitory effect on growth.
• Ehylene is responsible for positive geotrophic bending of roots
• It inhibits growth of lateral buds
• It stimulates fruit growth and ripening
• It stimulates abscission (formation of separation layer)
• Ethylene induces flowering
• It stimulates rooting
• It is responsible for breaking of  dormancy of seeds and buds
• It promotes yellowing of leaves
• It helps to determine the sex of monoecious flowers.
• It controls leaf bending.
• Ethylene release inhibits auxin synthesis and transport.
