Single nodes and axillary buds excised from adult trees of Myrtle (Myrtus
communis L.) grown in the field under natural conditions at Damascus
countryside (Ain Elfiegh) were used as primary explants, which were surfacedisinfected
by 70% Ethanol an
d Clorox containing 5.25 % Sodium Hypoclorite
with a drop of Tween 20 for different periods and concentrations before being
placed onto MS basal medium. Established cultures were then transferred onto
MS basal medium containing a combination of growth regulators at different
concentrations (BA at 2.22 and 4.44 μM) each with NAA at 0.54, 1.62, 5.4 μM
or 1.47 μM IBA with GA3 at 0.58 μM for all tratments. Multiplication rate of
12.8-fold was achieved every 4 weeks on MS medium supplemented with 4.44
μM BA with 1.47 μM IBA and GA3 at 0.58 μM.
