  • Haberlandt (Austria)
  • Cultivate isolated plant cells
  • in vitro on an artificial medium ---gt

Concept of Totipotency
1922 Kotte (student of Haberlandt)  
Improve medium sugar, Organic
N-compounds
Father of Plant Tissue Culture
10
Concept of Totipotency
Plants can be separated into their component
parts ( organs, tissues, or cells ), which can be
manipulated in vitro and then grown back to
complete plants.
