Whether it is a seedling pushing through the soil or a fruit ripening on a branch, every movement a plant makes is orchestrated by complex chemical messengers known as Plant Growth Regulators (PGRs) or Phytohormones. Derived from the Greek word hormaein, meaning "to excite," these natural molecules work in minute concentrations to produce substantial physiological changes. What Defines a Phytohormone? Unlike animals, plants do not have specialised glands for hormone product
