Callus Culture

• Use of callus and embryo cultures is mainly reserved for species of plants such as wheat or carrots in which the seeds might enter a dormancy stage.
  
  

Creating An Embryo Culture

• In a laboratory setting, plant embryo tissue is taken from the parent plant and placed on a growing medium to develop new embryos. These plant embryos can then grow into plants
  
  

Why Embryo Cultures Are Important

• An embryo culture, when embryos are taken directly from the plant, still will have the same genetic makeup of the parent plant without any alteration.
  
  

Development of Callus Cultures Through Embryo Cultures

• By developing a callus culture that changes the nature of the plant's genetics by growing it in a chemical environment, certain characteristics such as plant dormancy can be eradicated, and new embryos can be produced from the culture.
  
  

Callus Cultures Improve Plant Growth

• According an article published in the "Journal of Plant Biotechnology" in 1999, research in at the Isfahan University of Technology in Iran studied plants received from just an embryo culture versus both an embryo and callus culture. Research findings showed that the callus method frequently produced more plants as the medium on which they are grown enhanced plant growth.
