संकलन: Plant Growth Hormones (PGH)

Plant Growth Hormones, also known as phytohormones, play a crucial role in regulating various aspects of plant growth and development in agriculture. The main types of these hormones include auxins, gibberellins, cytokinins, ethylene, and abscisic acid. Auxins help in promoting root development and are widely used in plant propagation. Gibberellins are responsible for stimulating stem elongation, seed germination, and fruit development. Cytokinins support cell division and help delay leaf aging, which improves both crop yield and quality. Ethylene plays a key role in fruit ripening and flower development, making it useful for managing harvest timing. Abscisic acid helps plants cope with stress conditions like drought by regulating water balance. Overall, these hormones work together to optimize plant growth, increase productivity, and enhance crop quality in agricultural practices.
