Study of vegetative propagation by cuttings of Thymus satureioides

This work led to the vegetative propagation of thymus satureioides,aims to study the effect of the indole 3-butyric acid (iba) on rhizogenesis of two cuttings types (basal and summit). this plant species is widely used for its medicinal virtues. an experimental device was installed under glasshouse at the experimental station of the faculty of sciences of oujda. the results show that untreated basal cuttings have a low average rate of rooting (11%). moreover,the hormone treatment shows significant differences in the rooting rate (25%) for high concentrations of auxin (500 ppm). these types of cuttings are considered refractory to vegetative propagation. besides,the hormone treatment significantly improved the rate of summit cuttings rooting (rr=48% for c0 and 91% for c3 (500 ppm)). in addition,the hormone has a significant effect on the qualitative aspects of summit cuttings rooting of t. satureioides.
