ABSTRACT
The present study aimed at investigating the cutting propagation of Cordia mixa, a valuable timber and shade tree of very poor seed propagation and no literature were found concerning its vegetative establishment. In completely randomized experiments, soft and semi-hard wood cuttings (20 cm long) were taken early in the morning during spring and winter and planted in the common soils used in the educational farm at King Saud University. IBA and NAA auxins at 500 and 2000 ppm each were also checked for their influence on the cuttings. Shoot flushes were counted on weekly basis and number of roots was checked randomly after 2 months while the experiment was harvested, for final assessment, after five months. Results of the present study showed that autumn cuttings performed better than spring ones that did not root at all. Moreover, softwood cuttings rooted better than semi-hardwood cuttings especially in the peat moss and agricultural soils (averaging 40% each). However, auxins, may be due to their low concentrations adopted, did not affect roots, but affected on flushes as they significantly increased average number of buds and petiole length. For number of buds, NAA at 500 ppm concentration gave best results being highest in semi-hardwood cuttings (averaging 22.5). Whereas, there were no real differences between the auxins or the cutting types in case of petiole length.
