Sometimes, artificial application of plant growth hormones can also stimulate the plant to develop new foliar buds from the region where it is applied. In some plants like turmeric and carrot,food is stored in the root. The injured region develops new buds called foliar buds, which later give rise to these roots for new plants to grow.
