The Types of Inflorescences

  • Growth of plant organs can occur according to two different schemes:
  1. Monopodial
  2. Sympodial
  • In monopodial scheme of growth, the terminal bud continues to grow and remains intact.  It grows as a leader shoot. The lateral branching occurs with the help of axillary buds. There is a single growing point, hence monopodial.
  • In indeterminate inflorescence, the terminal bud does not cease to grow and never forms terminal flower. The lateral flowers and formed. Such inflorescences are also open inflorescences.
  • In determinate inflorescences, the terminal bud develops into terminal bud. It ceases to grow. The lateral flowers take over the main branching. Such inflorescences are also closed inflorescences.
  • Depending on whether the apex gets converted into a flower or continues to grow, there are two major types of inflorescences:
  1. Racemose: it is indeterminate and open type of inflorescence
  2. Cymose: it is determinate and closed type of inflorescence
