Growing deciduous fruit trees in the tropics - a new approach to an old problem


, : Growing deciduous fruit trees in the tropics - a new approach to an old problem. Acta Horticulturae (49): 109-111

The problem of dormancy breaking in warm climates is solved in Batu, East Java, Indonesia, by defoliating apple trees up to 4 weeks after harvest. This induces rapid lateral bud-break and increases blossoming which follows some 4 weeks later; since the crop is ready in another 5 months 2 harvests can be obtained in a year. In addition, the branches are bent to an angle of 60 deg and tied to pegs; this lessens apical dominance, reduces vigour and encourages earlier fruiting.
