Abstract : Five uniform trees of mango cv. Khiew Sawoey were drenched with 6 g paclobutrazol/tree 16 days after leaf emergence. Terminal shoots of the treated and control trees were collected weekly for anatomical studies. Apical meristems of control and treated trees slowly developed increasing amounts of leaf primordia and bud scales. After 91 days, 30% of apical buds on paclobutrazol-treated trees developed floral primordia. Of the treated shoots, 90 and 100% developed floral buds at 105 and 112 days after treatment, respectively. None of the terminal buds of the control trees developed into flower buds.
