For example, bananas are picked when green and artificially ripened after shipment by being exposed to ethylene. Calcium carbide is also used in some countries for artificially ripening fruit. When calcium carbide comes in contact with moisture, it produces acetylene gas, which is similar in its effects to the natural ripening agent, ethylene ...
In 1934, British biologist Richard Gane discovered that the chemical constituent in ripe bananas could cause ripening of green bananas, as well as faster growth of pea. He showed that the same growth effect could be induced by ethylene. [15] Reporting in Nature that ripe fruit (in this case Worcester Pearmain apple) produced ethylene he said:
This method is great to ripen bananas for recipes because heat brings out the fruit’s sugar. Bananas cannot be overly green when using this method. Put unpeeled bananas on a baking sheet and ...
Some foods which are picked when unripe, such as bananas, are cooled to prevent ripening while they are shipped to market, and then are induced to ripen quickly by exposing them to propylene or ethylene, chemicals produced by plants to induce their own ripening; as flavor and texture changes during ripening, this process may affect those ...
Either way, keep your bananas at room temperature while they ripen on the hook. 2. Buy green bananas. The easiest way to prolong your bananas’ shelf life is to buy the greenest bananas you can find.
Generally, fleshy fruits can be divided into two groups based on the presence or absence of a respiratory increase at the onset of ripening. This respiratory increase—which is preceded, or accompanied, by a rise in ethylene—is called a climacteric, and there are marked differences in the development of climacteric and non-climacteric fruits.

See ya, brown bananas! We scoured old cookbooks and interviewed experts to learn how to keep bananas fresh. The post 6 Ways to Make Your Bananas Last Longer appeared first on Taste of Home.
Gibberellins cause also seed germination by breaking the seed's dormancy and acting as a chemical messenger. Its hormone binds to a receptor, and calcium activates the protein calmodulin , and the complex binds to DNA, producing an enzyme to stimulate growth in the embryo.
