Bhau B. S., Wakhlu A. K., A highly efficient in vitro propagation protocol for elephant tusk cactus: Coryphantha elephantidens (Lem.) Lem., Journal of Genetic Engineering and Biotechnology, 2015, 13(2):215-219, doi: 10.1016/j.jgeb.2015.07.003
A comparison of Coryphantha elephantidens shoot multiplication from four explant types on MS medium with cytokinins. It analyses the effects of cutting, BAP, kinetin and the carbon source. It describes rooting and acclimatisation of propagated plants and presents a laboratory protocol for vegetative propagation.
