野生和人工培养蜜环菌菌索多糖含量及免疫活性的比较 |
| 2. | Objective to study the cell structure changes of gastrodia elata after armillaria mellea infection as well as the nutritional resource of this important medicinal plant
目的研究天麻营繁茎被蜜环菌侵染后细胞结构的变化，及天麻整个生长期的营养来源。 |
| 3. | Abstract : objective to study the cell structure changes of gastrodia elata after armillaria mellea infection as well as the nutritional resource of this important medicinal plant
文摘:目的研究天麻营繁茎被蜜环菌侵染后细胞结构的变化，及天麻整个生长期的营养来源。 |
| 4. | Method observation of the serial sections on the nutritional stems of g . elata , and measure new corms of g . elata when cut off the old corms connection with rhizomorph of a . mellea
方法作天麻营繁茎连续纵切片结合横切片观察；在天麻生长期切断其与菌材连接的蜜环菌索，测量新生麻生长情况。 |
| 5. | Conclusion after the rhizomorph of a . mellea infected g . elata nutritional stems , hyphal coils and the hyphal stream will breakthrough passage cells as well as large cells surround the whole nutritional stems , so the passage cells is the key nutritional resource in the whole growth period of g . elata
结论蜜环菌索侵入天麻营繁茎后，菌丝结、突破菌丝通道的菌丝流，及大型细胞等三层细胞层呈片状环周包围了整个营繁茎，菌丝通道是天麻整个生长期营养的补给线。 |
| 6. | Armillaria mellea ( m ) owned the most bands ; t3 had 3 specific bands secondly . m and t8 were distinguished using the 4 specific bands which were amplified through primer opb - 05i m , t8 and t2 were identified by 3 specific bands which were amplified through primer opn - 10 , these amplified specific bands by this primer distinguished the most samples . according to clustering tree plot of gastrodia elata bl
Ntsys软件聚类结果表明：采自同一地方(广元青川)不同地点的t5 ， t6具有最近的亲缘关系，其遗传相似系数达0 . 81 ；密环菌m与其它9种野生与栽培系的天麻的遗传距离最远，其遗传相似系数只有0 . 37 。 |
| 7. | 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。 |
| 8. | Only homothallic cbs g possessed a single independent lineage . both a . mellea and a . tabescens appeared in two groups . the two clusters of a . mellea correlated to the geographical origin of the isolates , one is the north american lineage and another is the european lineage
用11个种43个图谱的数据建立了聚类树图，可以清楚地见到9个类群，只有cbsg拥有一个单独的发育系，蜜环菌狭义种和假蜜环菌都存在两个不同的发育系，蜜环菌狭义种的两个发育系与地理起源有关，一个是北美菌株发育系，另一个是欧洲菌株发育系。 |
| 9. | Great diversity in genomic dna of gastrodia elata bl . and armillaria mellea . was also demonstrated by completely different bands of the rapd between various growing periods of t8 and m . the complete different bands of the rapd between m and the tuber of t8 might revealed that the genetic matter of m did not invade the inter area of gastrodia elata bl
2通过对同一株不同生长时期的天麻与蜜环菌的rapd扩增结果的研究表明：同一株天麻不同生长时期的dna不表现差异，而且与密环菌没有共同的条带，这说明密环菌与天麻的dna有较大的差异，特别是与块茎之间的差异说明密环菌的遗传物质在天麻的生长过程中侵入天麻块茎皮层以内的部位时已被同化。 |
