Plant hormones are crucial biochemicals that influence plant development and crop production under a variety of situations, including stress. Auxin, abscisic acid, ethylene, gibberellins, cytokinins, salicylic acid, strigolactones, brassinosteroids, and nitrous (nitric) oxide are examples of plant hormones. Plant hormones play an important role in plant development, starting with seed germination and ending with whole-plant senescence. They helps in flowering , aging , root growth , prevention or promotion of stem elongation ,fruit colour enhancement etc.
