Auxina

Auxins are plant hormones that play a crucial role in the growth and development of plants. They promote the growth of roots and stems, and are responsible for phototropism, where stems grow towards light, and geotropism, where growth occurs against gravity. Gardeners utilize auxins to root cuttings, encourage flowering, and increase fruit production.
