PINEAPPLE FRUITLET CORE ROT (BLACK SPOT) AND LEATHERY POCKET: REVIEW AND PROSPECTS |
| Author: | X. Mourichon |
| Abstract:
Penicilium funiculosum has been shown to be the main causal organism of the pineapple fruit diseases called fruitlet core rot (FCR) and leathery pocket (LP). These diseases occur in several producing countries and may result in important losses concerning fresh as well as processed fruits. Both FCR and LP result of preflower infection by P. funiculosum, but two distinct processes lead to either FCR or LP. Several factors seem to be implicated in the pathogenesis of P. funiculosum making these two fruit diseases very intricate. Some research allowed to display some aspects about the etiology of FCR/LP : 1. Importance of the inflorescence developmental stages (before anthesis) in relation to contamination. - 2. Implication of mites (Steneotarsonemus ananas). - 3. Importance of some environmental conditions. - 4. Physio-biochemical characteristics of the fruit during maturation. | |
