Small fruit size is one of the major problems in mandarin production. This experiment was conducted in order to increase fruit size and quality of Satsuma mandarin (Citrus unshiu) using synthetic growth regulators. Mature Satsuma mandarin trees with sour orange (Citrus aurantium) rootstock were treated with 2,4-Dichloro-phenoxy acetic acid (2, 4-D) and naphtaene acetic acid (NAA) at the concentrations of 0, 10, 30 and 60 mgl-1 and 0, 300, 400 and 500 mgl-1 respectively. Results indicated that auxins had effect on the size and diameter of fruits. NAA at the concentration of 400 mgl-1 and 2,4-Dat 30 mgl significantly increased fruit weight when compared with untreated control. In addition, pH of the fruit juice was also affected and showed an increase, however TSS was reduced. Both growth regulators increased juice content, but not the percentage. In conclusion, the marketability of fruits were improved by both growth regulators, and the best result and appearance was obsereved using 400 mgl-1 NAA.
