Lema-Rumińska J., Goncerzewicz K., Gabriel M., Influence of Abscisic Acid and Sucrose on Somatic Embryogenesis in Cactus Copiapoa tenuissima Ritt. forma mostruosa, The Scientific World Journal, 2013, 2013:513985, doi: 10.1155/2013/513985
The experiment concerns somatic embryogenesis in a horticultural monstrose form of Copiapoa humilis subsp. tenuissima, named in the title as C. tenuissima. It compares embryo development directly on tissue and through callus, and the effects of abscisic acid and sucrose concentrations.
