Fungi form mycorrhizae in plant roots and the hyphae take in carbon from plants through their epidermal cells and move mineral nutrients and water from soil to their epidermal cells ; this symbiosis is of high importance in studying biodiversity conservation , the origins and evolution of terrestrial plant , the rehabilitation and reconstruction of degenerated ecosystems , agriculture , horticulture and forestry 真菌在植物根系形成菌根后，菌丝通过根的皮层细胞获取植物提供的碳源，同时将矿物营养和水从土壤转运到皮层细胞，这种共生过程的研究在生物多样性的保护、陆生植物的起源与演化、退化生态系统的修复与重建以及农业、林业和园艺业的应用具有重要的意义。
The results show that the optimal temperature for the hypha growth , hypa color turned , and stroma differentiation is 22 . 7 , 20 . 2 and 18 . 1 , respectively , and the appropriate temperature for the hypha and stroma growth under artificial culture is 15 - 18 and 14 - 17 , respectively 结果表明，蛹虫草菌丝生长速率最大时的环境温度为22 . 7 ，转色的最佳温度为20 . 2 ，子座分化的最佳温度为18 . 1 ；在人工栽培时，适宜的发菌温度为15 ~ 18 ，子座生长的适宜温度为14 ~ 17 。
Result after g . elata nutritional stems infected by a . mellea , the rhizomorph of a . mellea separate into several hyphal layers and penetrate hyphal stream which infect into the cells of cortex layer in the direction of outside and infect directly into layer cells in the direction of inside , these hypha can be used the nutrition of g . elata the new corms will be stop growth if cut off the rhizomorph of a . mellea connected with g . elata 结果蜜环菌索侵入天麻营繁茎后，分成多个分枝的菌丝通道，菌丝突破通道形成菌丝流，向外侵入皮层细胞形成菌丝结，向内直接侵入大型细胞被天麻消化作为营养；切断天麻与菌材连接的蜜环菌索，新生麻就停止生长。
The third part studied ecological effect of combined pollution for hms in plearotus ostreatus , measured the lingth and anti - weed - moulds ability of hyphae , biomass of plearotus ostreatus , biovailability of hms , hms enrichment , the variety of hms toxicity and the transformation amd redistribution ability of hms . the ecological dffect of hms on plearotus ostreatus is reviewed . hms mentioned above were harmful to the growth and yield of pleurotus , ostreatus , but cd could enhance billogical efficiency 第三部分：研究重金属复合污染物对平菇生态效应的影响，分析了菌丝生长速度和抗杂性，平菇的生物量，重金属离子的生物有效性，平菇对重金属的吸收与富集，重金属毒性的差异和重金属离子的分配和迁移，综合分析了重金属的交互作用对平菇的生态效应。
After inoculation , all strains were examined by microscopy , hyphae or cells of all strains were observed , but none was seen in negative comparison . in the same time , originally fungi were isolated again in sabourud which showed that these fungi could grow and reproduce in these animals , but if they can cause infection or not will be make sure with impressionable animals 回接后所有实验菌种在显微镜下均可见有菌丝或菌细胞生长，而阴性对照组则未见生长，同时可以从沙堡氏培养基中再次分离得到该菌，说明这些菌种均可以在动物体内生长繁殖，但是否能真正引起感染，还需要进一步使用易感动物进行确认。
