Abstract

A pot experiment was done to improve the rooting ability of schefflera stem cuttings by using different media types (sand, sand: clay, sand: peat moss and vermiculite: peat moss as 1: 1, V/V), different indole-3-butyric acid (IBA) concentrations (0.0, 2000, 4000 and 6000 ppm) and their combination treatments. This experiment was conducted at a private Farm under a saran greenhouse, in Mansoura, Dakahlia Governorate, Egypt, during the two summer consecutive seasons of 2022 and 2023. Sand: peat moss, thereafter vermiculite: peat moss mixture media significantly enhanced rooting %, number of roots per cutting, fresh and dry root weights per cutting and produced the longest roots in comparing with the additional media that are being examined. Sand: peat moss medium recorded the highest values of leaf total chlorophyll content. The highest significant values of rooting parameters and total chlorophyll content were obtained with 4000 ppm of IBA compared to the other concentrations and control. In general, soaking schefflera cuttings base in IBA at 4000 ppm for 10 seconds and then culturing them in sand: peat moss medium enhanced rooting percentage and number of roots per cuttings compared to the other combinations under study. Moreover, examining the anatomical alterations of the adventitious root of schefflera cuttings cleared that culturing in various media under the influence of IBA increased the diameter of the xylem vessels, phloem, and xylem tissue, and root diameter.
