Current Question (ID: 12860)

Question:

Cousins confirmed the release of a volatile substance from ripened oranges that

Options:

1. Hastened the ripening of already ripened bananas
2. Hastened the ripening of unripened banana
3. Slowed the ripening of unripened bananas
4. Slowed the ripening of oranges

Solution:

Cousins confirmed the release of a volatile substance from ripened oranges that hastened the ripening of unripened bananas. This volatile substance is now known as ethylene and is a key plant hormone involved in various physiological processes, including the ripening of fruits. Ethylene promotes fruit ripening by triggering the expression of genes involved in the production of ripening enzymes. It is also involved in the senescence and abscission of plant organs, such as leaves and flowers.
