孢子形成菌

Result The cell of the fungi was oval and monopole budding. The fungi had deposition and zone in liquid medium, its colony was red with smooth and gray surface, regular edge and sticky texture in solid medium, and the fungi had no ascospore and could not produce pseudohypha. The fungi was negative through glucose ferment and it could assimilate potassium nitrate.

The test established optimal conditions for producing pycnidium that optimal medium was corn powder,optimal temperature was 25-30℃,optimal pH was 7-8.UV irradiation induced the forming of pycnidium.

最适合草茎点霉SYAU-06菌株形成分生孢子器的培养基为玉米粉培养基；最适温度为25-30℃，最适pH为7-8，而且光照有利于产孢，适量的紫外线照射可诱导分生孢子器的形成。

The characteristic in liquid culture of the purified strains were described, and the relation between the characteristic and the taxonomic traits was researched for the first time. The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

Soybean variety, temperature, humidity and illumination were factors influencing teleutosorus formation, among which temperature and variety being the major factors.

大豆锈菌可在大豆植株上形成冬孢子和冬孢子堆，田间在10～11月初形成，但数量较少。

This paper reviewed microsclerotia or spores in soil are stimulated to germinate by host root exudates, hyphae colonizes on the surface of root, pathogens penetrate epidermis and develop in cortex, expand on stem and leaf, and symptom development, shows that host plant develops various barriers to restrain this fungus invasion.

本文系统探讨了土壤中微菌核或孢子受寄主根系分泌物的刺激，开始萌发、产生的菌丝在寄主根表面定殖、穿过表皮、在皮层中发生及在寄主体内扩展和症状形成等黄萎病菌侵染棉花的过程，阐述了寄主植物形成多级防御反应阻击病原菌的入侵。

At first, optimization for the perfect stage production of M. grisea was investigated in vitro. The number of perithecia and ascospores, the percentage of viable ascospores were markedly increased when juice of mature tomato was used, pH was adjusted around 5. 5 and 0.1％CaCO〓 was added in oatmeal tomato agar medium.

本研究首先选用自然成熟的番茄榨汁和燕麦片作为培养基的主要组分，通过调节培养基pH值在5.5左右并添加0.1％CaCO〓途径优化了稻瘟病菌有性世代形成的条件，显著增加了稻瘟病菌子囊壳形成的数量和子囊孢子的成活率。

In the present study a solution culture method was developed to test the effects of mycorrhiza formation on organic acids.

本试验改固体培养基为营养液培养基，采用静止的培养方法，在培养四个月时发现，萌发孢子的菌丝生长良好，菌丝已经侵染了根段，形成了根内菌丝，同时也观察到大量辅助细胞的存在；培养六个月后，形成了成熟的新孢子，说明营养液静止培养菌根共生联合体的方法是成功的。

Through the selection of culture medium and the mutant of mycelium that has a high production of PUPAS oil , the oil containing mycelium can be obtained with fermentation, and the dry mycelium contains 42.75挆47.78% oil.

本课题通过研究，选出了深黄被孢霉Mortierellaisabellina株作为摇瓶小试菌株，该株生长快，菌丝多，利用培养基原料能力强，易于形成孢子，生物量49g干菌体/L发酵液，含PUFAs46.61％，其中GLA2.3％。

Turgor pressure builds up inside the appressorium,forcing a penetration peg into the plant tissues;this is then followed by invasive growth and eventurally conidiation of the fungus.

该菌侵染循环过程经历了分生孢子与植物表面接触、萌发、附着胞分化、侵入栓的形成以及侵染生长，并最终产生新的分生孢子导致新一轮的病害循环。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.
