Paper analyzes four biological effect of arbuscular mycorrhiza including promote plant growth enhance absorption of mineral nutrition , improve water metabolism and resolve the problem of re - inseminator in fruit tree mechanisms of four arbuscular mycorrhizal biological effect are explained . as well as paper brings forward the arbuscular mycorrhizal necessity in fruit tree 文章分析果樹叢枝菌根生物肥料的四大生物效應,即促進生長、增強礦質營養的吸收、改善水分、解決果樹重茬及其機理,提出叢枝菌根在果樹應用中的必要性。

Arbuscular mycorrhiza can improve the ability of resisting drought from several aspects : hyphal enhances plants ' chances of absorbing water from soil ; it can improve plants ' phosphorus and another minerals ' nutrition , increase the content of chlorophyll ; observably enhance transpiration and stoma conduction ; reduce the flow of water , permanent languish point , stoma resistance ; change the balance of hormone , promote accumulation plant proline and capability of nitric reductive enzyme 叢枝菌根真菌可以通過以下幾個方面增強植物抗旱性:通過菌絲增加植物對土壤水分的吸收;改善植物的磷營養及其他礦質元素營養;能顯著提高蒸騰速率和氣孔導度;干旱條件下降低植株葉片水勢、永久凋萎點、葉片飽和虧、氣孔阻力和恢復時間;改變激素平衡。

In this paper , bioremediation technology of contaminated soil with organic pollutants was summarized , which were technologies of the microorganism remediation , the phytoremediation and the mycorrhiza remediation for contaminated soil , the future developments of these bioremidation technologies were prospected as follows : when the efficient surfactants was used to enhance phytoremediation systems , its optimum doses should be considered ; studying on the important role of the rhizosphere exudates in the phytoremediation , seeking the best matching partners between plant and microorganism and the best mycorrhizal funguses to improve pollution degradation 摘要綜述了有機污染土壤生物修復的三種技術,即微生物修復技術、植物修復技術、菌根生物修復技術及其研究現狀,并展望了這三種生物修復技術今后的研究方向,如利用表面活性劑提高植物修復效率時,應考慮其最佳使用量;加強研究根分泌物在植物修復土壤污染中的作用;進行植物微生物聯合體篩選技術研究;篩選促進污染物降解的優良菌根菌種等。

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,菌絲通過根的皮層細胞獲取植物提供的碳源,同時將礦物營養和水從土壤轉運到皮層細胞,這種共生過程的研究在生物多樣性的保護、陸生植物的起源與演化、退化生態系統的修復與重建以及農業、林業和園藝業的應用具有重要的意義。

The results showed that lamellae were fit tissue for mycelia isolation , and success percentages of mycelia isolation with media pdas , pdaw , bm , pda are 74 . 4 % , 35 . 5 % , 15 . 6 % and 8 . 9 % respectively . the results also showed that stipe , mycorrhizae , and soil with the fungi are not fit for tricholoma matsutake isolation 另外,馬鈴薯葡萄糖麥數濾汁培養基( pdaw ) 、 bm培養基、 pda培養基也從菌褶2曾東方博士論文:腐生與共生食用菌菌絲體分離、培養及其dna鑒定研究分離到松茸菌絲體,分離成功率依次是35 . 5 % 、巧

The survey shows that there found mycorrhizae in all the 7 tree species beside prunus ansu . through differentiating , we understand that these ectomycorrhizal fungi are 8 different species which are subordinated to 6 families and 7 genera 結果表明:除山杏未發現外生菌根真菌共生外,其它7個樹種上均發現了菌根真菌的共生現象。

With soybean and corn , fungi can grow with plant root into mycorrhiza as a bioremediation method which is effective and economical on treating soils contaminated by petroleum hydrocarbons 在污染土壤中種植玉米和黃豆,通過施加不同的菌劑,采取菌劑和菌根強化修復措施,在一個生長季節后,土壤中石油類污染物降解率可達53 % ~ 78 % 。

Some form symbiotic associations with algae or cyanobacteria to form lichens , while others form extremely important mycorrhizae with the roots of many plants , including most forest trees 真菌是土壤和淡水中主要的分解者,一些與藻類或藍細菌共生形成地衣,還有一些真菌與許多植物包括大多數林木的根形成大量的菌根。

Arbuscular mycorrhizae have ability to improve mineral quality of fruit tree , replacing the fertilizer so called the biological fertilizer 摘要叢枝菌根有增強果樹吸收礦物質營養的特性,起到代替肥料的作用,故稱為生物肥料。

Arbuscular mycorrhizae are the most widespread mutualistic symbionts among the symbionts between plants and microbes 摘要在植物與微生物的共生體中,最廣泛的互惠共生體就是叢枝菌根。
