摘要
Serpula himantioides是一种分布于全球的木材腐朽真菌,会导致多个树种的心材腐朽。我们对日本两年零六个月来发生的S. himantioides子实体进行了调查,以了解其生物学特性。子实体在秋季成熟,出现在活的 Chamaecyparis pisifera、Chamaecyparis obtusa、Larix kaempferi 和 Cryptomeria japonica 树木上,也出现在死树和土壤上。在对三个环形地块进行评估后发现,在心材腐烂程度最严重的地块,活树上出现 S. himantioides 子实体的几率最低。此外,在树干下坡方向出现子实体的频率更高。利用成对相关函数进行的分析表明,随着心材腐烂程度的加深,带有子实体的活树的空间分布模式可能会从密集型变为随机型。最后,利用广义线性模型和广义线性混合模型研究了影响 C.pisifera、C.obtusa 和 L. kaempferi 子实体发育的因素,发现子实体的有无与心材腐朽之间没有明显的关系。因此,我们认为健康的活树和处于心材腐烂早期的活树都可能出现子实体。
Occurrence and Characteristics of Serpula himantioides Fruiting Bodies on Living Trees in Japan.
Serpula himantioides is a globally distributed wood decay fungus that causes heartwood decay in several tree species. We investigated the occurrence of S. himantioides fruiting bodies in Japan for two years and six months to characterize their biology. The fruiting bodies matured in autumn and occurred on living Chamaecyparis pisifera, Chamaecyparis obtusa, Larix kaempferi, and Cryptomeria japonica trees, as well as on dead trees and soil. Assessing three circular plots, the incidence of living trees with S. himantioides fruiting bodies was lowest in the plot with the most advanced heartwood decay. Furthermore, fruiting bodies occurred more frequently in the lower slope direction of the trunk. Analysis using the pair correlation function suggested that the spatial distribution pattern of living trees with fruiting bodies may change from intensive to random with heartwood decay progress. Finally, according to generalized linear and generalized linear mixed models, which were used to investigate the factors affecting the development of fruiting bodies in C. pisifera, C. obtusa, and L. kaempferi, no clear relationship was found between the presence or absence of fruiting bodies and heartwood decay. Thus, we suggest that fruiting bodies can occur in healthy living trees as well as in living trees in the early stages of heartwood decay.
期刊介绍:
Journal of Fungi (ISSN 2309-608X) is an international, peer-reviewed scientific open access journal that provides an advanced forum for studies related to pathogenic fungi, fungal biology, and all other aspects of fungal research. The journal publishes reviews, regular research papers, and communications in quarterly issues. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on paper length. Full experimental details must be provided so that the results can be reproduced.
