The experiment included seven treatments with antioxidants using the concentrations 125, 250 and 375 mg L-1 for each in addition to the control treatment (with distilled water only). The offshoots were sprayed four times. The results of the study showed the following: 1) The treatment of spraying with Toc at a concentration of 375 mg.L-1 recorded a significant difference in the increase of the height of the offshoot, and in the leaf content of the soluble protein f.w. The treatment also recorded the highest amount of P and K that reach 1.60 and 4.23 mg.g-1 d.w, respectively, and led to a decrease in the amount of Cl-, as it rea...
