Propagation through modified organs

Several species of plants ensure their propagation with the help of modified organs that serve as the propagules. Following are some such special organs

Sucker

  • A sucker is a small plantlet that appears around a mother plant from its base. These plantlets remain attached to the mother plant and continue to grow.

  • They assume to grow as independent plants when they are separated from the mother plant and planted else where.

  • Suckers are the propagating material of medicinal plants such as Aloe vera (Kalabanda), Aegle mormelos (Maredu), Holorrahena antidysenterica etc.
Tuber
  • Tuber is the swollen and fleshy underground stem or root. These are found attached at the base of the stem.

  • On separation, tubers or pieces of a tuber will grow into independent plants.

  • Tuber is the propagating material of many medicinal plants such as Asparagus racemosus (Challa gaddalu, Pillipichara), Dioscoria spp. (Chedupaddudumpa, Karrapendalamu), Adenia hondala, Gloriosa superba (Kalappa gadda), Ipomoea spp. (Nagaramukkatte, Thooti koora, Nelagummudu) etc.

Rhizome
  • Rhizome is the swollen and compressed underground stem with short scaly leaves and vegetative buds.

  • A piece of rhizome with a bud, if planted, will grow into an independent plant

  • Rhizome is the propagating material of medicinal plants such as Ginger (Allam), Turmeric (Pasupu), Costus speciosus (Chengalvakoshtu, Kushthamu) etc.
