Ethylene sensor could help monitor plant health

To control flowering and fruit ripening, plants release the gaseous hormone ethylene. Environmental conditions, including drought, salinity and pathogens, can also cause levels of the hormone to fluctuate. Therefore, monitoring ...

Wood-based catalyst to keep fruit fresh

If freshly bought bananas are stored in a full fruit basket, then they won't stay yellow very long. Just a few days later, the crooked fruits take on a brownish color and are more likely to be thrown away than be eaten. The ...

Ethylene

Ethylene (IUPAC name: ethene) is a gaseous organic compound with the formula C2H4. It is the simplest alkene (older name: olefin from its oil-forming property). Because it contains a carbon-carbon double bond, ethylene is classified as an unsaturated hydrocarbon. Ethylene is widely used in industry and is also a plant hormone. Ethylene is the most produced organic compound in the world; global production of ethylene exceeded 107 million tonnes in 2005. To meet the ever increasing demand for ethylene, sharp increases in production facilities are added globally, particularly in the Persian Gulf countries and in China.
