摘要: 锥栗在贮藏期间易发生霉烂和腐败,主要原因是病原菌侵染。本研究以闽北主要栽培品种油榛锥栗为材料,从腐败栗肉组织中分离、纯化病原菌,结合形态学与分子生物学方法进行鉴定,构建系统发育树,以明确分离菌株的分类地位。结果表明,共鉴定出的致病菌株包括 Gd21Ⅱ、Dd13、Dc21、Ga11、Gd21Ⅰ、Bc21、Gd12Ⅱ、Fd12Ⅱ、Ad11、Fd12Ⅰ、Fd13、Dd11 和 Gb23,分别归属于青霉属Penicillium mallochii、枝孢属Cladosporium sp.、葡萄座腔菌Botryosphaeria dothidea、德巴利氏酵母属Debaryomyces robertsiae、假丝酵母属Candida sp.、间座壳属Diaporthe sp.和假单胞菌属Pseudomonas oryzihabitans。本研究通过对锥栗贮藏期间主要病原菌的分离与鉴定,明确了闽北锥栗致病菌的种类及其系统分类,为锥栗采后贮藏保鲜技术的目标致病微生物提供了标靶目标,并为锥栗保鲜新技术开发提供了理论依据。

Abstract: Castanea henryi is susceptible to spoilage during storage, primarily due to pathogenic infection. In this study, the main cultivated variety C. henryi 'Youzhen' in northern Fujian were used as experimental material. Pathogenic fungi were isolated and purified from decayed kernel tissues, followed by identification based on morphological and molecular biological methods. A phylogenetic tree was constructed to clarify the taxonomic status of the isolated strains. The results showed that the pathogens responsible for C. henryi spoilage included Gd21Ⅱ, Dd13, Dc21, Ga11, Gd21Ⅰ, Bc21, Gd12Ⅱ, Fd12Ⅱ, Ad11, Fd12Ⅰ,Fd13, Dd11, and Gb23, which were respectively classified as Penicillium mallochii, Cladosporium sp., Botryosphaeria dothidea, Debaryomyces robertsiae, Candida sp., Diaporthe sp., and Pseudomonas oryzihabitans. Through the isolation and identification of major pathogenic fungi during storage, this study clarifies the species and phylogenetic classification of the spoilage-causing microorganisms, providing a theoretical basis for the development of postharvest storage and preservation techniques for C. henryi. It also provides a theoretical basis for the development of new preservation technologies for C. henryi.
