Mechanisms of Plant Growth

The video tutorial explores plant growth, starting with the role of meristem cells in primary and secondary growth. It delves into plant hormones like auxin, cytokinin, gibberellins, abscisic acid, and ethylene, explaining their functions in growth regulation, stress response, and agricultural applications. The tutorial highlights how these hormones influence plant direction, flowering, fruiting, and stress management, providing insights into their practical uses in agriculture.
