| Abstract | ||||
| The current study was carried out to evaluate the impact of indole-3-butyric acid (IBA) at 0 and 400 ppm, chitosan (40 ppm), Aloe vera gel and their combinations on rooting percentage, number of days for root appearance and root parameters of Conocarpus erectus L. air-layers. Results showed that treating C. erectus air-layers with IBA at 400 ppm, chitosan at 40 ppm and Aloe vera gel (100%) increased root percentage, decreased the number of days to root appearance and improved root characteristics (root number, root length, root fresh and dry weights) as well as content of total phenols, total carbohydrates percentage and C/N ratio comparing with the control. Aloe vera gel either alone or combined with IBA at 400 ppm were more effective than those treated with chitosan alone or combined with IBA. The best results were obtained by application of IBA (400 ppm) combined with chitosan (40 ppm) and Aloe vera gel. Therefore, it is advisable to apply any of these treatments when propagating Conocarpus erectus by air-layering for commercial production. | ||||
