Ziziphora canescens is a species of important medicinal plants in Syria due
to its medicinal properties as antibiotic, flavors and spices in various foods.
This plant is important, especially in folk medicine in some areas (Kalamoon)
on the one ha
nd, and retreat of its spread which may lead eventually to its
extinction on the other hand, so a protocol for rapid micropropagation has
been developing by using lateral and apical buds on nutrient media MS
supplemented with different types and concentrations of plant growth
regulators.
A detailed in vitro multiplication system for rapid micropropagataion of the
Hypericum perforatum L. has been developed. Shoot tips and axillary buds
excised from this plant which were collected from Tartous explants and surface
disinifected then cultured on MS (Murashige and Skoog 1962) medium.
This research was conducated on Ceratonia siliqua L. in vitro to study the effect of
some growth regulators in both multiplication and rooting stage. And determine the best
concentrations wich lead the highest rate of multiplication (interms of number of shoots
and length), and the best rooting (interms of percentage of rooting, number of roots and
length).
