Among the recent line of technological innovations, nanotechnology takes a promising position in agriculture and food production. Nanotechnology permits definite advances in agricultural research, such as reproductive science and technology. This investigation is interested in studying the in vitro effect of carbon nanotubes (CNTs) on callus, embryogenesis, embryo germination and elongation as well as rooting stage of date palm. Carbon nanotubes concentrations were investigated as 0.0, 0.05 and 0.1 mg/l. Results showed that CNTs affect all stages of micropropagation of date palm. Callus fresh weight showed the optimum value at 0.05 mg/l. In embryogenesis stage, CNTs decreased the number of embryos compared with the control while, increased number of germinated embryos and root number. Carbon nanotubes gave a significant enhancement for shoot length and leaf number in elongation stage. Similarly, it enhanced root number, root length, plantlet length and hairy roots. Chemical analysis as chlorophyll a, b, carotenoids, flavonoids, antioxidant enzymes and nutrients concentration and uptake were determined.
