An experiment conducted to study the effect of pre-harvest application of growth regulators on the post-harvest quality of guava cv. Lucknow-49 fruits, revealed that treatment of fruits with GA3 (100 ppm) gave significantly better results than the other treatments. The higher concentration of GA3 (100 ppm) recorded the highest mean values of moisture content (82.09%), ascorbic acid (225.9 mg/100 g), total sugars (7.30%), chlorophyll content (1.560 mg/g) and total phenols (0.220%) compared to the rest of the treatments at the end of nine days of storage.
