| Abstract | ||||
| This search was conducted to investigate the impact of Humic acid (H.A.) fertilizer (0.0,10.0,20.0 and 30. 0 g l-1) and different media (100% peat moss , 50% peat moss + 50% perlite and 50% peat moss + 50% sand) and their combinations' effect on rooting and growth of Dracaena marginata under greenhouse conditions at the Nursery, Department of Floriculture, Ornamental Horticulture and Landscape Gardening, Faculty of Agriculture, Alexandria University, Egypt during the growing seasons 2021 and 2022. The results showed that terminal cuttings pretreated with H.A. combined with media had significant effects on survival %, rooting %, roots number /cutting, root length (cm), root fresh and dry weight (g). The highest significant values of rooting and growth obtained when Dracaena cuttings cultured in medium composed of 50% peat moss + 50% perlite combined with Humic acid (H.A) at 30.0 gm l-1 concentration. As well as, the highestsignificant results for total carbohydrates and total leaf chlorophyll content (a + b) were obtained after applying the aforementioned treatments. Chemical analysis also indicated that N, P and K content were markedly increased as H.A. concentrations increased up to 30.0 gml-1 with the growing media of peat moss 50% + perlite 50%. Dracaena cuttings in control treatment (without H.A.) grown in 100% peat moss recorded the lowest significant mean values for all characteristics under study in both seasons. Therefore, it is suggested that growing high-quality Dracaena plants for various aesthetic reasons be performed by treating Dracaena cuttings with H.A. at 20.0 or 30.0 gml-1 and cultivating in a mixture of 50% peat moss + 50% perlite. | ||||
