Fruitone C.P.A. application on pineapple fruits

Abstract

The field experiment was carried out at Progresso Farm, São Vicente de Paula district, Araruama, Rio de Janeiro State, Brazil. The effect of five rates (0, 50, 100, 150 and 200 ppm) of chlorophenoxy propionic Acid (Fruitone C.PA.) applied on Smooth Cayenne pineapple fruits was tested. Fruitone was applied six weeks after the inflorescence emission. Statistical analysis showed that the rates of 100, 150 and 200 ppm reduced the crown length. The rates of 150 and 200 ppm reduced the crown weight. On the other hand, 150 and 200 ppm rates causad damage in fruit crowns. It is recommended to use a 100 ppm rate to reduce fruit crown length. The lack of rain after Fruitone application affected the hormone effect on the fruit weight.
