Question

What hormone helps plants respond to drought?​

Answer 1

Answer:

Cytokinins are the plant hormones that promote the lateral bud growth, stimulate seed germination and delay the leaf senescence. Ethylene is a gaseous plant hormone that is stimulated by the auxins, promotes fruit ripening, enhances senescence and leaf abscission; promote root hair formation and flowering.

Answer 2

Drought is an environmental stress caused due to the water scarcity. In such conditions, the plants avoid or inhibit the seed germination and growth. The plant favors the state of dormancy. Auxins are the plant growth regulators or hormones that promote stem elongation, the formation of adventitious and lateral roots, fruit development and inhibit the leaf abscission.
