Read the scenario below.

You receive a bouquet of flowers and want to make them last as long as possible.

ethylene

gibberellins

cytokinins

auxins

Answer: Auxins

Auxins are plant hormones with several roles one of which is delaying (inhibiting) abscission of leaves or flowers. This is done by applying auxin to the flowers, since young flowers have been known to consist of high auxin content that however lowers as it ages.

Thus, applying auxin to the bouquet of flowers would make them last as long as possible
