Calcium Chloride Applications to Improve Fruit Quality on Bruised and Diseases of Pineapple (Ananas comosus (L) Merr)

Abstract

The problems faced by producer canned of pineapple are the high of bruised which caused by the mechanical damage such as pressure, vibration during harvest, transport to the fruit processing and pathological damage caused by fruit diseases. The objective of research was to obtain the treatment time of CaCl2 applications and dosage of CaCl2 to improve the fruit quality of pineapple. This research used Split Plot Design and each treatment replicated 3 times. The main plot is time of CaCl2 applications that consists of three levels, thats are : 90 day after forcing (daf) (W90), 120 daf (W120) and twice time of CaCl2 applications on 90 and 120 daf (W90+120). The sub plot is dosage of CaCl2 that consists of three levels, thats are : 50 kg ha -1 (C50), 75 kg ha -1 (C75) and 100 kg ha -1 (C100). The results of research showed that the combined treatment twice time of CaCl2 applications on 90 and 120 day after forcing and dosage of CaCl2 100 kg ha -1 produces the calcium content on fruit is higher than the other combined treatments and produce the fruit texture, percentage of fruit diseases and percentage of bruised are lower than the other combined treatments.
