Forest declines are usually complex multifactorial phenomena that involve interactions between different factors. The possible interaction between different types of mycelial pathogens was investigated through artificial inoculation of oak seedlings, involving two root rot basidiomycetes, Collybia fusipes and Armillaria mellea, and two Phytophthora species, P. cinnamomi and P. cambivora. These pathogens were inoculated onto young Quercus robur saplings in greenhouse conditions, either alone or combining a root rot basidiomycete with a Phytophthora species. Three out of the four Phytophthora spp.*root rot basidiomycete combinations tested resulted in significantly greater damage to the oak host than the sum of the damages induced by the individual pathogens. This positive interaction could be significant in oak decline syndrome. 相似文献

鸡枞菌生物多糖含量较高,对人体具有抗肿瘤和增强机体免疫力等多种生理功能,但由于自身生长条件要求较高和生态环境的变化,导致采用传统方法培养的鸡枞菌生物多糖含量较低。通过测定鸡枞菌生物多糖含量、菌体单位体积湿重等指标,在单因素试验的基础上,以多糖含量为考察指标,采用响应面法优化培养时间、培养温度、初始pH值,研究鸡枞菌生物多糖含量达到最大值的最佳培养条件。结果表明,最佳培养条件为：葡萄糖添加量2.50%,蛋白胨添加量0.25%,培养时间7 d,培养温度27.6 ℃,初始pH为7.0,此优化条件下得到的生物多糖含量达2.71 g/L。该研究为液态培养鸡枞菌提高生物多糖含量提供了理论依据。 相似文献

紫外线诱导对药用真菌菌丝体生长的影响 总被引：8，自引：0，他引：8
用紫外线照射羊肚菌、松茸、金针菇菌丝体，研究了不同照射时间对菌丝生长速度、菌落直径、菌丝生长势及菌丝干重的影响。结果表明：紫外线照射对羊肚菌和松茸菌丝体的生长有不同程度的促进作用，其中以照射4min处理组的作用最明显，且松茸菌丝体的生长（P＜0．05－P＜0．001）比羊肝菌（P＜0．05－P＜0．01）强；紫外线照射对金针菇菌丝体的生长有显著的抑制作用（P＜0．001）。 相似文献

Collybia fusipes is the cause of a root rot of Quercus petraea (sessile oak), Q. robur (pedunculate oak) and Q. rubra (red oak). This parasite is often reported to cause problems in stands of red oaks and field evidence suggests that this North American oak species is more susceptible than the two European oak species. Young saplings of the three oak species and of chestnut, Castanea sativa, in the glasshouse, and also mature sessile and red oaks growing in the same stand were inoculated with C. fusipes to compare their susceptibility. Red oak, both as young seedlings and mature trees, was more susceptible to C. fusipes than sessile oak. Chestnut seedlings were as susceptible as sessile oak. Susceptibility of pedunculate oak seedlings was intermediate between red oak and sessile oak. In one experiment this species was significantly less susceptible than red oak, and in the other it was as susceptible. 相似文献
