| Abstract:
Dragon fruit (Hylocereus undatus (Haw.)) experiments carried out during 1998–2000 indicated that harvesting was optimal 28–30 days after flowering, on the basis of the indices of colour, total soluble solids (TSS), titratable acidity and colour. Best practice also included spraying the fruit with a mixture of gibberellic acid,  -naphthalene acetic acid (NAA) and  -NAA at a formulation of 8, 150 and 400 ppm, respectively, on the 11th day after flowering.
This treatment increased fruit weight, TSS and flesh and bract firmness.
