бананы обрабатываются гормонами

[jayrandom]

Бойтесь, о питающиеся бананами пищевые пуристы! Не обрабатывали ли ваш банан этиленом?

Ethylene is the only gaseous hormone in the plant world; it is a simple hydrocarbon gas that is derived from the amino acid, methionine, via an unusual cyclic compound which is also an amino acid, ACC (1-aminocyclopropane-1-carboxylic acid).

The gas is used commercially for ripening fruit, particularly bananas.
