LESIONS ON PINEAPPLE FRUIT DUE TO CRACKING BETWEEN INDIVIDUAL FRUITLETS |

| Abstract:
Cracks between the individual fruitlets on a ‘Queen’ pineapple fruit can vary from light or heavy suberisation ("interfruitlet corking") to a fissure. The factors that influence the appearance of such cracks were investigated. The effect of plant size, fruit enlarger and moisture, as well as the role of leathery pocket mite and Penicillium infection were investigated in four different trials. The seasonal appearance as well as the position of the cracks on the fruit were determined. It was found that fissures occurred more on the upper than the lower half of the fruit and more on the north-eastern and north-western side of the fruit, i.e. the parts most exposed to the sun. Fruits that were more exposed (smaller plants) had an increased number of fissures which appeared in the later phase of fruit ripening (2–3 weeks before harvesting). A seasonal effect was evident. | |
