one simple technology used by farmers to ripen fruits is to place it in an airtight room and induce ripening through smoking. explain how smoke causes ripening of fruits
The fruit ripening caused by the plant hormone, ethylene. It converts the plant starch into sugar. Ethylene is produced and released by rapidly-growing plant tissues and is released by the growing tips of roots, flowers, damaged tissue, and ripening fruit. Natural ripening in some fruits is a slow process, which leads to high weight loss, desiccation of fruits and uneven ripening.
So, artificial ripening has become essential. Ethylene gas is used commercially to ripen tomatoes, bananas, pears, and a few other fruits. It is called smoking. This ethylene gas turns the plant starch into sugar. It is a quick process and provides even ripening.
Smoking process has some disadvantages.
