The modifying effect of growth regulators on bud burst, flower bud formation and sex expression in olives varies greatly according to cultivar, concentration and time of application. Cycocel 200, 500 mg/l, ethephon 200 mg/l and SADH 2000 mg/l stimulated bud burst and flower bud formation in the 'Blanquetta' cv. A noticeable increase in the percentage of perfect flowers was obtained by 100 mg/l of kinetin, and 200 mg/l of Cycocel in the cv. 'Picual', Ethephon 200/1, Cycocel 200 mg/l and SADH 2000 mg/l considerably increased the percentage of perfect flowers in the cvs 'Blanquetta', 'Serrana' and 'Picual'. Treatments at green cluster stage were not effective
