This studies were conducted to investigate the effects of hexaconazole on growth of watermelon(Citrullus lanatus Schrad) and ethylene evolution from gourd(Lagenaria siceraria Standl). While foliar application of hexaconazole exhibited inhibition effect, little or no inhibition was found in the plants treated with soil drench application. The plant height and number of internode in watermelon were significantly inhibited at 7 days after treatment(DAT), but no significant difference was found at 42 DAT. No significant difference was found in site of female flower setting when treated with hexaconazole. The length of branch was significantly inhibited at the 2nd or the 3rd internode. It was suggested that the inhibition of stem elongation was related with application timing of the chemical. Hexaconazole increased ethylene evolution more effectively at earlier stage of gourd, but after 5 DAT ethylene evolution was decreased.
