Application and Ethephon of Calcium Chloride for Improving the Fruit Quality of Pineapple

Abstract

The objective of research was to obtain the treatment time of CaCl2 applications, dosage of CaCl2 and ethephon applications to improve the fruit quality of pineapple. This research used Split-Split Plot Design and each treatment replicated 3times. The main plot is time ofCaCl2 applications that consists of three levels, those are 90 day after flowering (daf), 120 daf and twice of CaCl2 applications at 90 and 120 daf The sub plot is dosage of CaCl2 that consists of three levels, those are 50 kg ha\u27, 75 kg ha\u27 and 100 kg ha\u27, The sub sub plot is dosage of ethephon that consists of two levels, those areO L ha\u27 and 2,5 L ha\u27, The results showed that the combined treatment ofCaCl2 application on 90 daf, dosage of CaCl250 kg ha\u27 and dosage of ethephon 2.5 L ha\u27 produce distribution external fruit maturity level of 25% and 50% higher than the other treatments. Combined treatment twice of CaCl2 application on 90 and 120 daf with dosage of CaCl2 100 kg ha\u27 produces calcium content higher than the other treatment and produce fruit texture, percentage of fruit diseases and percentage of fruit bruised lower than other treatments. Ethephon application had noeffect on calcium content but decreasing fruit texture, percentage of fruit diseases and improved percentage offruit bruised. CaCl2 and ethephonapplications didnot affect the total soluble solid, total acidity and vitamin C
