| Abstract:
Five uniform mango trees, Mangifera indica L., cv. ‘Khiew Sawoey’ were drenched with 6g/tree paclobutrazol 16 days after leaf emergence. Terminal shoots of the treated and control trees were collected weekly for anatomical studies. Apical meristems of both control and treated trees slowly developed increasing amounts of leaf primordia and bud scales after the paclobutrazol treatment. Ninety one days after paclobutrazol application 30% of the apical buds from the paclobutrazol treatments developed floral primordia. Ninety and 100 % of the treated shoots developed floral buds at 105 and 112 days after treatment respectively. None of the terminal buds of the control trees developed into flower buds. | |
