Ethylene (Science: chemical plant biology) plant growth substance (phytohormone, plant hormone), involved in promoting growth, epinasty, fruit ripening, senescence and breaking of dormancy. A mixture of gases is obtained from which ethylene is separated. Ethylene is an important hormone concerned with ripening. Ethylene is a hormone required to trigger fruit ripening, and it can be blocked by using synthetic compounds, such as 1-methyl-cyclo-propene (1-MCP). All these six atoms H-C-H form an angle of 117.4°, close to the 120° to form a hybridized carbon sp². It is actually a gaseous hormone and it hastens fruit ripening. It breaks the dormancy of seeds, buds and storage organs. The proliferation of papers and review articles on ethylene in recent years has been largely due to the tremendous role that Induces root growth to increase the capability of water and mineral absorption. Ethylene in Plant Biology, Second Edition provides a definitive survey of what is currently known about this structurally simplest of all plant growth regulators. Plant Hormones Definition.
