Abstract : The effects of soil application of 10 ml paclobutrazol and foliar application of 20 ppm NAA, 1% urea, 1% potassium nitrate, 200 ppm ethrel and 5000 ppm mepiquat chloride on the flowering of 10-year-old mango cv. Alphanso trees were determined in a field experiment conducted in Coimbatore, Tamil Nadu, India. Soil application with 10 ml paclobutrazol resulted in the longest panicle (31.57 cm), number of branches per panicle (13), total number of flowers per panicle (620), number of hermaphrodite flowers (189.67) number of male flowers (425) and hermaphrodite flowers (30.59%). The male:hermaphrodite flower ratio was highest with application of 1% potassium nitrate.
