盘菌

Infection by S. sclerotiorum causes serious damage to oilseed rape, soybean, sunflower and the mustard family vegetables. Because S.

草酸是核盘菌致病过程的决定因子，核盘菌在油菜、大豆、向日葵与十字花科蔬菜等植物上引起严重的菌核病。

Investigation on discomycetes diversity in Tibet has been done in recent years, the results show about 200 species presented here, those known systematic species belonging to 4 orders, 17 families and 62 genera.

通过对西藏盘菌的采集调查表明，西藏目前已知盘菌为200种左右，其中已确定系统位置的种类分隶属于4目17科62属，尚有一部分种类目前未能确定它们的系统地位。

The present species in Tibet are very similar to that of distributing in North America and in North Europe, this suggests that their fungal floras may have a certain relationship in discomycetes, and the floristic nature is closed.

统计分析结果表明，在物种组成上，西藏现存盘菌多与北美及北欧分布的盘菌成分类似，联系较为紧密，盘菌区系性质相似。

Species diversity of Lachnum from Huangshan Moutains Anhui China weresurveyed, Nine taxa were reported. Tissue isolation was performed on 97 discomycetes specimens fromHuangshan Mountains, 33 filament products were obtained.

我国安徽黄山等地物种丰富，但是对粒毛盘菌属物种多样性的报道却相对较少，本研究对黄山等地粒毛盘菌属的物种多样性进行了分类学研究，报道了黄山粒毛盘菌属9个分类单元。

Among them, few species being utilized except some of Morchella.

在资源价位方面，多数盘菌体现的是生态价值，只有少量大型盘菌如羊肚菌属的种类目前被开发利用。

Sclerotiorum were screened out, sclerotia of which could germi-nate to form apothecia at 20℃ without any conditioning.

首先从158个单菌核分离物中筛选出了6个能够在高温（20℃）下直接形成子囊盘的核盘菌菌株。

Thirty Sclerotinia strains were collected and the biological characteristics as well as their pathogenicity were tested.

将供试的30个核盘菌菌株进行菌丝生长速度、菌核产量等生物学特性和致病力的测定，结果表明核盘菌S。

It was showed that the growth speed of hypha, sclerotinia production and the pathogenicity of strains had little relation with host and geographical location. The ability of oxalic acid production of strains had positive relation with the pathogenicity. In order to study the nutrition aptness, 8 kinds of culture mediums were tested and the result showed that S.

sclerotinia不同菌株菌丝的生长速度、菌核产量、致病力与其地理来源和寄主来源关系不大，对12个代表菌株的草酸产生能力的测定表明，菌株的草酸产生能力和病菌的致病性基本呈正相关，致病力较强的菌株草酸产生能力较强；采用8种培养基对代表菌株营养条件进行了研究，结果表明核盘菌S。

S. trifoliorum is similar in biology and morphology to S. sclerotiorum , but S. minor produces much smaller sclerotia and generally produces apothecia less frequently in nature.

三叶草核盘菌在生物学和形态学上比核盘菌要小，小菌核产生的菌核非常小并且在自然状况下一般很少产生子蘘盘。

Additionally, one SsDRV-free strain Ep-1PNA183av that showed hypovirulence was isolated from a mutant of healthy strain Ep-1PNA183, this strain also immunizes the infection of SsDRV, it would be a valuable material to study on the interaction between SsDRV and its host. Surprisingly, we discovered that SsDRV could be transmitted into S. nivalis (in the same genus to S. sclerotiorum) when cultured side by side on PDA plate, this discovery may supply new evidence for the exchange of genetical elements among different species in fungi; the transmission of mycovirus to other species showed that the limitation of vegetative imcompatiblity among different strains might not be key factor to determine the efficiency of biological control with hypovirulence associated mycovirus.

发现了1株不携带SsDRV的核盘菌弱毒力菌株，该菌株对SsDRV具有显著抗性，是研究SsDRV与寄主互作的宝贵材料；还发现SsDRV可以在核盘菌种间传递，深入研究将为生物在种间的遗传物质交换提供了新的证据，也将为广泛利用弱毒相关病毒控制植物病害提供理论依据。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
