Combination of the Auxins NAA, IBA, and IAA with GA₃ Improves the Commercial Seed-Tuber Production of Potato (Solanum tuberosum L.) under In Vitro Conditions

Figure 3

Effects of 1.0 × MS medium containing 1 mg L⁻¹ of NAA, IAA, and IBA, with and without 0.25 mg L⁻¹ GA₃, on the number of nodes and leaves of cvs. Pasinler, Granola, and Caspar. Means of different values from four replications (𝑛=4) are statistically different using Duncan’s multiple range test at the 0.01 level of significance. (T1: 0.25 mg L⁻¹ GA₃, T2: 1 mg L⁻¹ NAA, T3: 1 mg L⁻¹ IAA, T4: 1 mg L⁻¹ IBA, T5: 0.25 mg L⁻¹ GA₃ + 1 mg L⁻¹ NAA, T6: 0.25 mg L⁻¹ GA₃ + 1 mg L⁻¹ IAA, and T7: 0.25 mg L⁻¹ GA₃ + 1 mg L⁻¹ IBA.)
