This experiment was designed to improve the in vitro production system of apple rootstock M.26 as being influenced by the growth regulators, TDZ, BA, IAA, IBA, zeatin, and GA$_3$. Different levels of potassium humate (KH), known as cytokinin and auxin-like substance, were also supplemented to the MS basal medium along with IBA 0.6 mg/L to find out it effect on root formation in apple rootstock M.26. ID initiate and establish the in vitro multiplication of shoots byway of meristem culture, MS medium added with zeatin 1.0 mg/L was found to be the most suitable, showing the 100% of survival rate of shoot tips. A combination of thidiazuron (TDZ) 0.2 mg/L and NAA 0.5 mg/L promoted the shoot proliferation when shoot tips were used as explants. MS basal medium plus IBA 0.6 mg/L was very effective for root induction, but an addition of potassium humate (250 mg/L) to the medium containing IBA 0.6 mg/L stimulated the induction and proliferation of the rook by far the better.
