Abstract

Two independent factorial experiments were conducted at the Conservation Glasshouse of the Egyptian National Gene Bank, ARC, Giza, Egypt during the 2020 and 2021 seasons to enhance the rooting of wounded terminal stem cuttings of jojoba plants as well as the growth and chemical composition of the resulting transplants. The first experiment examined the effect of nano-Fe naphthaleneacetic acid (nFe-NAA) at 0, 100, 200, and 400 ppm, indole-3-butyric acid (IBA) either in its traditional form (t-IBA) at 0, 1000, 2000, and 4000 ppm or in nanoparticles loaded on Fe (nFe-IBA) at 0, 100, 200, and 400 ppm, and their interactions. Meanwhile, in the second experiment, the effect of NAA in nano form (n-NAA) at 0, 100, 200, and 400 ppm, IBA either in traditional form (t-IBA) at 0, 1000, 2000, and 4000 ppm or in nano form (n-IBA) at 100, 200, and 400 ppm, and their interactions were studied. In the first experiment, the sole and combined treatments improved the mean values of rooting percentage, number of roots per cutting, and root length, as well as branch length, number of branches per transplant, number of leaves per transplant, and fresh and dry weights of branches and roots, chlorophyll a, b, carotenoids, total sugars, indoles, and phenols in the newly formed transplants, with few exceptions in the two seasons. However, the combined treatments, especially the quick dipping of wounded cuttings' bases in either 200 or 400 ppm nFe-NAA solution and then in either 200 or 400 ppm nFe-IBA one, resulted in the best results in both seasons. A similar trend was also obtained in the second experiment, where the combinations surpassed the individual treatments, especially the combinations of dipping in n-NAA at either 200 or 400 ppm + n-IBA at either 200 or 400 ppm afterwards, as such four combinations scored the best results over all the other combinations. Besides, interacting between 4000 ppm t-IBA and n-NAA at either 200 or 400 ppm concentrations gave better results in some characters. Therefore, it is recommended to use both IBA and NAA rooting hormones together in the form of nanoparticles at either 200 or 400 ppm concentrations for each, either loaded or non-loaded on iron oxide, to get the best rooting of jojoba wounded cuttings and the highest quality of the new transplants from a commercial point of view.
