摘要/Abstract

摘要： 为了探讨AM真菌对干旱区珍稀濒危植物引种过程中的成活、生长保育的影响研究，在盆栽条件下，选取具有代表性的7个珍稀濒临灭绝植物物种，在引种过程中定向接种AM真菌，通过分析植株的生长状况及AM真菌的侵染率，初步筛选在干旱区珍稀濒危植物引种过程中，具有应用价值的AM真菌与植物最佳共生模式。结果表明：7种濒危植物与AM真菌能形成共生关系，但植物与菌种间侵染率存在显著差异。既形成了良好的共生关系又能促进濒危植物生长的最佳组合有：AM真菌F.mosseae与白麻或乌拉尔甘草或蒙古莸的共生，真菌D.eburnea与新疆沙冬青的共生、真菌C.claroideum或F.mosseae与中麻黄的共生、真菌C.lamellosum与胀果甘草的共生、真菌C.etunicatum与蒙古沙冬青的共生。表明濒危植物与AM真菌之间存在一定的生态适用性选择关系，而且在利用AM真菌对濒危植物引种繁育时，必须要考虑他们间的生态适用性关系，才能充分发挥AM真菌的功能。这对干旱区珍稀濒危植物的引种繁殖意义重大。

Abstract: In order to study the effects of AM fungi on the survival and growth of rare and endangered plants in arid regions,a pot experiment was conducted by selecting seven representative species of rare and endangered plants and six AM fungi. In the process of introduction and planting,AM fungi were inoculated. By analyzing the growth status of the plant and the infection rate of AM fungi,the optimal symbiosis pattern of AM fungi and endangered plant was selected. The results show that seven endangered plants could form symbiotic relationship with AM fungi,but there was a significant difference in the infection rate of AM fungi with the difference plants. The highest rate of infection is Poacynum pictum with F. mosseae,Ammopiptanthus nanus with D. eburneum/F. mosseae,Ephedra intermedia with C.lamellosum,Glycyrrhizauralensis with R. aggregatum/C. claroideum/F. mosseae/C. lamellosum,Glycyrrhizainflata with C. etunicatum/D. eburneum/C. claroideum,Ammopiptanthusmongolicus with C.etunicatum,Caryopteris mongholica with C. etunicatum/D. eburneum/C. claroideum. The best combination of symbiotic relationship for promoting the growth of endangered plants is the symbiosis of AM fungus F. mosseae with Poacynum pictum or Glycyrrhiza uralensis or Caryopteris mongholica,the symbiosis of fungus D. eburneum and Ammopiptanthus nanus,the fungus C. claroideum or F. mosseae symbiosis with Ephedra intermedia,the symbiosis of fungus C. lamellosum with Glycyrrhiza inflata,the symbiosis of fungus C. etunicatum and Ammopiptanthus mongolicus. The study results demonstrate a certain ecological suitability relationship between endangered plants and AM fungi. It is essential to consider their ecological suitability relationship when using AM fungi for introduction and planting of endangered plants. Within this suitability relation,AM fungi functions well. This is of great significance to the introduction and reproduction of rare and endangered plants in arid area.
