Read this Q&A for a brief introduction to IBA, kinetin and inositol—three compounds that aid in plant growth and functioning—and learn how they can help optimize plant performance.
What are IBA and kinetin, and how do they benefit plants?
IBA (which stands for indolebutyric acid) and kinetin are two different types of plant growth regulators or hormones. IBA is an auxin that is produced in the plant’s leaves and shoots. IBA travels downwards to the roots and stimulates early and improved root growth, which increases plant vigor and the plant’s ability to fight off stress throughout the growing season. Kinetin is a cytokinin that is reduced in the root tips. Kinetin travels up the plant, directing seven physiological functions of plant growth.
