Abstract: The effect of PP333 of three concentrations on Navel Orange (Washington Navel Orange) were studied in this paper. The results showed that 100ppm and 500ppm PP333 treatments could increase the rate of the single flower shoot with leaves and inhibit the summer shoot sprouting. The setting fruit rate of fruit shoots and the yield of Navel Orange increased after the two concentrations were used on the Navel Orange trees twice each year. PP333 has not any bad effects on the fruit quality.

Key words: NAVEL ORANGE, PP333(PACHLOBUTRAZOL), SETTING FRUIT RATE OF FRUIT SHOOTS, PHYTOHORMONE, YIELD
