Abstract (AB)	Increase of sucrose content following Polaris application were similar when determined by polarimetric and gas liquid chromatography analytical methods. The results showed that increases of pol per cent cane represented true increases of sucrose. Treatment with the ripener also lowered the levels of both glucose and fructose. Increases in sucrose content were however, influenced to a greater extent by the geographical sector of the island than by soil type. Flowered and vegetative stalks responded equally well when Polaris was applied during the flag stage of the high flowering variety S17. Rain up to 5 mm during or just after spraying reduced response. The parameters which must be used to determine the optimum dosage for Polaris treatment are cost of Polaris and its application; its effect on sucrose content; yield after application and yield for regrowth crop.
