In vitro plant regeneration of Alnus acuminata H.B.K. ssp. acuminata and its root nodulation by Frankia

open access: yesPlant Cell, Tissue and Organ Culture, 2005
A procedure for in vitro plant regeneration of Alnus acuminata from epicotyls with cotyledonary buds was developed using different media formulations with different growth regulators and carbon sources. The development of multiple buds on explants at the initiation step was obtained with MS at 1/2 strength with either 1 or 2μM of BAP but not without it.
