PGR stands for Plant Growth Regulators, which are substances used to regulate various physiological processes in plants. They can promote or inhibit growth, influence flowering and fruiting, and improve stress resistance. Common examples include auxins, gibberellins, and cytokinins, which are used in agriculture and horticulture to enhance crop yield and quality. PGRs play a crucial role in modern plant management practices.
