Learn the Science Underlying Tissue Culture Propagation 

Plant tissue culture is a propagation technique that involves growing new plants from tiny pieces of  sterilised plant tissue, commonly on the surface of an agar-based growth medium, to give an aggregation of undifferentiated plant cells. 

This means the initial growing cells are neither leaves, stems or roots.

Once the mass becomes large enough, hormones can be added to the growth to cause the cells to change into roots, stems and foliage.

Student Comment:

"This is the first correspondence course I have done and I have thoroughly enjoyed it and I just wanted to say a big THANK YOU. I appreciate everyone's effort in such a professionally-run organisation with seamless administration. The office staff's happy can-do attitude, their fast responses to all queries, tutor Shane Gould's quick turnaround in assignment marking and his supportive and motivational feedback and last but not least, the sound subject guides. Most importantly I hope my thanks and appreciation can be communicated to all the staff who have supported me long the way of my learning! I work full time and study on the weekend but really don't stop thinking about what gardening solution I need in order to answer my assignments every day of the week. Thank you for such a great learning experience and I cant wait to start the second half of my course!!"

Lesson Structure

There are 9 lessons in this course:

  1. Introduction including a review of basic plant nutrition.
  2. Plant Nutrients.
  3. The Laboratory
  4. Micropropagation Techniques
  5. Plant Hormones
  6. The Tissue Culture Environment
  7. Commercial Applications
  8. Taking Plants out of Culture
  9. Culture of Selected Species

Each lesson culminates in an assignment which is submitted to the school, marked by the school's tutors and returned to you with any relevant suggestions, comments, and if necessary, extra reading.
