Colletotrichum species associated with mango (Mangifera indica L.) stem-end rot
- 13 Downloads
A symptom of stem-end rot was observed on fruits of mango cv. Falan in a hypermarket in Penang Island, Malaysia. Colletotrichum asianum and C. siamense were isolated from the diseased fruits. Identification of fungi was based on morphology and on ITS, GADPH and ACT gene sequencing and phylogenetic analysis. A pathogenicity test was conducted on three cultivars of mango (Chok Anan, Falan and Waterlily), on wounded and unwounded fruits. Both Colletotrichum species caused rotting symptoms on wounded and unwounded fruits of all cultivars. Both species were re-isolated from the diseased fruits, thereby fulfilling Koch’s postulates. This is the first report of C. asianum and C. siamense associated with mango stem-end rot in Malaysia.
