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 GA 3 (100 ppm) gave significantly better results than the other treatments. The higher concentration of GA 3 (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.
