Question

Why sugar canes ends after they are cut are dipped into IBA prior to sowing.?

Answer 1

Sugar cane ends are dipped in IBA prior to sowing to promote rooting at the cut end.

Explanation:

IBA (Indole-butyric acid) is a synthetic auxin. It resembles IAA (indole-acetic acid) , a natural auxin, in its role in promoting rooting of cuttings.

The auxins are known to enhance rooting of cuttings in many plants. Sugar cane cuttings are dipped in IBA for sometime before planting in soil. It hastens the rooting at the cut end that is buried in soil.

Thus the percentage of sugar cane cutting surviving and growing into new plants is increased by giving prior treatment with IBA.* *
