Definitions

  • Phytohormones are biologically active organic compounds which in minute quantities function to promote or modify plant growth such as root and bud formation.
  • Phytohormones are classified as auxin, cyto inin, gibberellin and abscisic acid types as relating to different plant growth regulating activities.
  • Auxins affect cell division and growth, and promote elongation of plant shoots and other specific growth effects.
  • Cytokinins affect the organization of dividing cells, and promote elongation of root cells.
  • Abscisic acids exhibit abscission- accelerating activity. Abscisic acid is utilized in somatic embryogenesis which employs tissue culture techniques for generating multiple embryos from donor plant tissue. Important beneficial effects derive from the use of phytohormones as plant growth regulators in agricultural applications, which include improved seed germination; promotion of rooting; increased resistance of plants to frost, fungal and insect attack; increased uptake of inorganic constituents from the soil; increased photosynthetic power; stabilization of chlorophyll; reduction in fertilizer requirements; increased crop yield; production of seedless fruits; herbicidal activity; and the like.
