Vachellia tortilis (family: Fabaceae) is a very well-known species in the savannah areas of Africa. It is commonly known as the umbrella thorn because of the shape of the tree canopy. The trees are highly drought resistant and have many uses, requiring successful multiplication. The seeds are however difficult to germinate and prompted an investigation into germination methods that might aid in this process. The seeds were collected removed from the pods and sterilized using 70% ethanol. After applying various scarification methods the seeds were subjected to three different photoperiod environments all at a constant 25°C. Mechanically scarified seed, under 24 h dark conditions resulted in the highest germination percentage.
