摘要
2009年在四川省攀西地区的石榴上发现一种毁灭性的新病害,且有逐年加重危害的趋势,已对石榴生产造成了巨大威胁。通过对发病植株的症状观察,病原菌的分离培养和显微形态特征观察,rDNA-ITS序列分析,及致病性测定,最后确定该病害是由甘薯长喙壳Ceratocystis fimbriata侵染引起的。该病害在印度和中国云南蒙自石榴产区曾有发生报道,但在四川省石榴产区为首次报道。
A new serious disease was found on pomegranate in Panxi Region of Sichuan Province in 2009, and it has become a severe threat to pomegranate production due to its increasing infection in recent years. Disease symptom observation, pathogen isolation and culture, morphological observation, rDNA-ITS phylogenetic analysis, and pathogenicity test were conducted, and the pathogenic fungus was finally identified as Ceratocystisfimbriata. This disease has been found in India and Mengzi of Yunnan Province. It is the first report in Sichuan Province
