Effect of Indole-Butyric Acid (IBA) Concentration and Growing Medium on the Rooting of Common Myrtle Cuttings (Myrtus communis L.)

Abstract

This study was conducted in a private nursery near the city of Al-Dana, northwest of Syria, in 2023. The study aimed to propagate myrtle (Myrtus communis L.) vegetatively using several treatments of indole-butyric acid (IBA) at several concentrations (0, 1000, 3000, 5000 ppm), to determine the best concentration.

The results showed that the best concentration was 5000 ppm, which achieved the highest rooting rate, reaching 93% in the soil mixture medium, and 47% in the pyrene medium. The results also showed that the same concentration (5000 ppm) was the most effective in increasing the number and length of roots, which reflects its positive effect on the rooting process. These results indicate the importance of using high concentrations of indole-butyric acid (IBA) and choosing the appropriate agricultural medium to improve the rooting effectiveness of myrtle cuttings, and increase the success rate in rooting, which enhances the possibility of propagating this plant
