Cytokinins are a class of plant hormones that play a crucial role in regulating growth and development. They promote cell division, which helps plants grow and develop new tissues. Cytokinins are primarily produced in the roots and are transported to other parts of the plant, influencing processes like shoot formation and leaf expansion. These hormones also help delay aging in plants by promoting the growth of new cells and tissues. In addition, cytokinins work alongside other hormones, such as auxins, to ensure balanced growth. Understanding cytokinins is essential for improving agricultural practices and enhancing crop yields.
