Abstract

Treatment with indole-3-butyric acid (IBA) showed a significant effect on the rooting ability of young offshoots of two reputed Moroccan date Palm cultivare, Boufeggous (BFG) and Mejhoul (MJH). While 73.6 of rooting (the highest percentage for both genotypes confounded) was induced by 5 IBA, only 51.2 of offshoots produced roots without auxin. Further more, untreated offshoots formed fewer roots than those treated with IBA. Variation in rooting among offshoots from the two cultivars was highly significant in response to IBA: offshoots from MJH rooted highly (78.6) with 5 IBA, while the highest rooting percentage (73.7) was induced with 7 IBA in BFG. Moreover, offshoots from MJH produced significantly more roots per rooted offshoots and were more affected by the inhibitory effect of high concentration (15 IBA) than those from BFG. On the other hand, treatments with IBA combined to IAA were unfavourable for rooting. But combined treatments IBA-NAA, showed a significant effect when the IBA/NAA ratio was superior to 1. © 2003, Taylor & Francis Group, LLC.
