LAU students cloned an African violet plant as they learned about “plant tissue culture,” a widely used technique that has many scientific and commercial applications.
The two-month procedure started with a fingernail-sized leaf fragment and ended in several “copies” of the original plant. The fragment was grown into a big blob of tissue in a Petri dish until “plantlets” sprouted from it. The plantlets were then separated to grow independently.
“This process requires accuracy and avoiding contamination to work out successfully,” said Assistant Professor Sima Tokajian, who supervised the project by the Plant Physiology (Fall 2005) class at the Byblos campus.
The technique, also known as micropropagation, is possible because all plant cells have the ability to generate a whole new plant given the required nutrients and hormones.

The students now have first-hand experience in a technique that has wide commercial applications as it can produce numerous identical plants in a short time.
Plants produced through micropropagation are uniform in size and shape as they are genetically identical. They are almost guaranteed to be disease-free and can be produced year-round in highly controlled chemical and physical environments away from seasonal changes.
The technique is used around the world to mass-produce plants, flowers and vegetables. Dr. Tokajian hopes it will encourage students to pursue income-generating projects after they graduate.
