Axillary shoot proliferation in cultures of explants from mature Juniperus oxycedrus trees.

We developed procedures for the micropropagation of Juniperus oxycedrus L. using shoot apices or nodal segments from mature plants. Of the media and explants examined, best culture establishment was obtained with shoot apices cultured on modified Schenk and Hildebrandt medium (SH medium) without growth regulators; however, shoot multiplication was only achieved when shoot apices isolated from shoots grown on SH medium without growth regulators were subcultured on SH medium containing 0.5 micro M benzyladenine. None of the auxins and methods tested for root induction provided satisfactory results.
