Abstract: Dragon fruit (Hylocereus undatus) has played an important role in horticulture of Vietnam for many years. White flesh dragon fruit variety was cultivated commercially in the Southern of Vietnam. The yield and quality of the fruits can be affected by using plant growth regulators. The present study aimed to evaluate the influence of GA3 and NAA on yield and fruit quality of five year old white flesh dragon fruit in Cho Gao district, Tien Giang province. The field experiment was carried out on randomized complete block design (RCBD) with four replications and five treatments. The treatments included GA3 30 ppm, GA3 40 ppm, the combination of GA3 + NAA (30 ppm + 20 ppm), GA3 + NAA (40 ppm + 20 ppm) and the control. The treatments were applied at 7, 14, and 21 days after fruit set. The use of GA3 + NAA (40 ppm + 20 ppm) increased flesh firmness (1.08 kg/cm2), fruit length (12.01 cm), fruit weight (562.08 g/fruit), fruit yield (35.05 kg/tree), and improved fruit peel luminosity. According to the findings, combining GA3 and NAA at appropriate concentrations can improve yield and fruit quality in white flesh dragon fruit.
