AXILLARY SHOOT PROLIFERATION IN CULTURES OF EXPLANTS FROM MATURE JUNIPERUS-OXYCEDRUS TREES

We developed procedures for the micropropagation of Juniperus oxycedru s L. using shoot apices or nodal segments from mature plants. Of the m edia and explants examined, best culture establishment was obtained wi th 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 mediu m without growth regulators were subcultured on SH medium containing 0 .5 mu M benzyladenine. None of the auxins and methods tested for root induction provided satisfactory results.
