Effect of chlorophenoxipropionic acid applied at different times on pineapple cv. Pérola

Abstract

This trial was carried out at the Campo Experimental de Quiçamã, at Macaé, RJ, Brazil. Effects of chlorophenoxipropionic acid (Fruitone C.P.A.) application, at 12, 13, 14 and 15 weeks after the flowering induction on pineapple crop were studied. One hundred milliters of a 100 ppm (a.i.) water solution of the acid were applied, sprayed on fruits and plants. The best time for the product application was 15 weeks after flowering induction, which produced fruit twice as heavier as the one of the control, with also larger length and diameter. Reduction in the total soluble solids content was noticed, mainly when applied 15 weeks after flowering induction.
