Abstract
Torreya grandis cv. Merrillii is an important economic tree widely cultivated in hilly subtropical areas in China and some parts of Japan and Korea. Crown and root rot was found on T. grandis in Zhejiang Province of China. Three isolates with similar morphology were isolated from diseased samples, and used for identification and pathogenicity tests. The pathogenicity of the isolates was confirmed by fulfilling Koch's postulates. The pathogen was identified as Fusarium commune based on morphological characteristics and phylogenetic tree constructed by combining ITS and TEF-1α gene sequences. This is the first report of F. commune causing crown and root rot on T. grandis in China.
大叶香榧（Torreya grandis cv. Merrillii）是一种重要的经济树种，广泛栽培于中国亚热带丘陵地区以及日本和韩国的部分地区。中国浙江省发现了大叶香榧的冠腐病和根腐病。从病害样本中分离出了三个形态相似的分离株，并进行了鉴定和致病性试验。分离物的致病性根据科赫推定得到证实。根据形态特征以及结合 ITS 和 TEF-1α 基因序列构建的系统发生树，确定病原菌为镰刀菌。这是中国首次报道 F. commune 在鹅掌楸上引起冠腐病和根腐病。
期刊介绍：
This peer reviewed, highly specialized journal covers forest pathological problems occurring in any part of the world. Research and review articles, short communications and book reviews are addressed to the professional, working with forest tree diseases caused by fungi, bacteria, nematodes, viruses, and phytoplasms; their biology, morphology, and pathology; disorders arising from genetic anomalies and physical or chemical factors in the environment. Articles are published in English.
Fields of interest: Forest pathology, effects of air pollution and adverse environmental conditions on trees and forest ecosystems.
