Studies on the fungal flora in New Zealand and Tasmania

1.关于植物病原真菌的研究结果关于哪种种子真菌与日本农作物的商业种子有关的信息很少。从日本十字花科植物种子上发现的链格孢菌种通过与新西兰的该属分离物的比较而被鉴定。我们的结果表明，甘蓝种子上的交链孢属与西兰交链格孢菌相同，在新西兰引起墙花腐烂。从新西兰进口的农产品在日本市场上经常因霉变而腐烂。对新西兰储存和销售的蔬菜和水果的采后真菌进行了检测。真菌的光谱与在日本观察到的有所不同。关于内生真菌的研究结果对内生真菌与其宿主涂料之间的关系的研究表明，生防剂具有潜在的用途。然而，这项研究应该从日本的第一步开始。新ZE…玻璃内生菌分布及研究策略的信息综述更多的Aland被承担了。从日本归化植物中获得的分离株的特征目前正在进行中。初步测试表明，在新西兰和塔斯马尼亚采集的Notofagus树上与Cytaria gard相关的真菌可能是相同的。这是首次尝试将该真菌从羊栖菜中分离出来。新西兰氨真菌的研究为了弄清在用尿素或氨盐处理后，特定种类的真菌在自然土壤上的先后出现情况，在新西兰的几个选定地点进行了定期观察。此外，还观察了负鼠身体降解过程中真菌区系的演替。与北半球的蘑菇一样，结出的蘑菇本质上也是Sanie。一些不明身份的事件的发生表明了这种差异。这些研究在南半球尚属首次尝试。菌根的研究结果。真菌分析表明，该菌属于外生菌根真菌。而澳大利亚Cortinarius austrarisis菌丝垫较厚，菌根形态独特。我们的观察表明，新西兰森林中真菌的生态位类似于北半球的一些木耳。现对新喀里多尼亚采集的菌根真菌标本进行检测。结果采集食用菌和微真菌标本，进行纯培养分离。例如非枝菌科真菌和木霉。6.物种。收集了许多日本草本植物所缺乏的高等植物标本。因此，我们可以弥补新喀里多尼亚标本的短缺。我们还收集了与这些植物相关的真菌。辨认工作现正进行中。较少

1. Results on plant pathogenic fungiThere is scanty information as to what kind of seed-borne fungi are associated with commercial seeds of crops in Japan. Alternaria species found on cruciferous plants seeds in Japan were identified by comparisons with New Zealand isolates of the genus. Our results indicate that an Alternaria on cabbage seed is identical with A. Cheiranthus which causes deterioration of wallflower in New Zealand.Agricultural produces imported from New Zealand are often decayed in Japanese market by moulding. Post-harvest fungi on vegetables and fruits stored and sold in New Zealand were examined. The spectrum of fungi was somewhat different from those observed in Japan.2. Results on endophytic fungiResearch on the relationship between endophytes and their host paints has indicated the potential use of biocontrol agents. However, the study should begin with the first step in Japan. Survey of information on distribution and research strategy of glass endophyte in New Ze … More aland was undertaken. Characterization of isolates obtained from naturalized plants in Japan are now in progress. A preliminary test indicated that the fungi associated with Cyttaria gall on Notofagus trees collected in New Zealand and Tasmania might be identical. This is the first attempt to isolate the fungus from Cyttaria gall.3. Study on ammonia fungi in New ZealandTo clarify the sequential occurrence of particular species of fungi on natural soils after treatment with urea or ammoniuiti salt, periodical observation was done in several selected locations in New Zealand. Further, succession of mycoflora during degradation process of an opossum corpse was observed. Mushrooms fruited were essentially the sanie as those in Northern Hemisphere. Some unidentified ones occurred indicate the difference. These studies are the first attempt in Southern Hemisphere.4. Results on mycorrhizal. fungiAnalysis of SHIRO formed by Hebeloma victoriensis revealed that the fungus was belonging to ectomycorrhizal. While, Cortinarius austrariensis had thick mycelial mat layer with morphologically peculiar mycorrhizae. Our observations suggested that an ecological niche of the fungus in New Zealand forest was similar to some Agarics in Northern Hemisphere. Specimens of mycorrhizal fungi collected in New Caledonia were examined now.5. Results on edible or useful fungiSpecimens of edible or useful mushrooms and microfungi were collected and pure culture isolation were made. Examples are Aphyllophoraceous fungi and Trichoderma. species.6. Other resultsWe collected many specimens of higher plants which were lack in Japanese herbaria. Thus we could make good the shortage of specimens proper to New Caledonia. We also Collected fungi associated with these plants. Identification work is now in progress. Less
