| 摘 要： | 近年,在广东徐闻凤梨种植基地生产的凤梨果实在采后贮藏过程中发生一种果肉腐烂病害,发病率达10%左右,并有逐年加重危害的趋势。为了明确该病的病原菌,本文通过果实组织分离和接种试验获得1个致病菌株,通过形态学观察和TEF-1α序列分析,确定该病的病原菌为凤梨镰孢菌Fusarium ananatum,这是该菌所致凤梨小果芯腐病在国内的首次报道。

| Abstract: | A disease of pulp rot was frequently found on stored pineapple fruits after harvest in pineapple planting base in Xuwen County of Guangdong Province in recent years, and the disease incidence even reaches about 10% in seriously infected pineapple garden. One pathogenic isolate of Fusarium was obtained by fruit tissue isolation and further pathogenicity test proved that it was pathogenic to pineapple. Based on morphological characteristics and TEF-1α gene sequence analysis, the isolate was identified as Fusarium ananatum. It is the first report of the pathogen responsible for pineapple fruitlet core rot in China. |
