Question

What are gaseous hormones? Give example

Answer 1

Answer:

Ethylene is a gaseous plant hormone also known as the ripening hormone. It is synthesized in ripening fruits, flowers, leaves, and even roots. ... This hormone also induces leaf abscission, seed germination, leaf and flower senescence.

Answer 2

• Ethylene is a simple, gaseous hydrocarbon and is a naturally occurring plant hormone.
• Ethylene is a gaseous plant hormone (phytohormone) produced by almost all parts of the plant but meristematic tissues are considered as active sites for its production.
• It acts for fruit development and ripening, controls leaves and flower abscission.
• Being a gaseous hormone it diffuses to other parts of the plant from its site of synthesis.
