Abstract
To investigate the effect of GA availability on fruit cracking of Neipling Stayman apple, trees were sprayed in spring with Promalin (0, 20 and 40 ppm) and paclobutrazol (PBZ) at 250 ppm (repeated 0, 3 or 5 times).

PBZ increased soluble solids content of fruit but such effect was nullified by the presence of Promalin; fruit length was increased by Promalin and reduced by PBZ. Promalin, contrary to expectation, did not reduce cracking while PBZ significantly increased it.
It is suggested that the ineffectiveness of Promalin may be due to unsuitable timing of treatments.
