The effect of arbuscular mycorrhizal fungi (AMF) an six plant species that frequently grow in areas of Mediterranean climate in south-east Spain was studied. In semi-arid soils, the most abundant AMF was Glomus aggregation Schenck and Smith, followed by Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe. The vascular plant species studied were Dittrichia viscosa (L.) W. Greuter (Asteraceae); Dactylis glomerata L., Piptatherum miliaceum (L.) Cosson, and Slipa tenacissima L. (Poaceae); Retama sphaerocarpa (L.) Boiss., and Ulex parviflorus Pourret (Fabaceae). Legumes were studied with single and dual symbiosis (Rhizobium and AMF). In a greenhouse experiment, inoculated plants developed better than noninoculared controls, as shown by dry weight and tissue N and P content. Plants inoculated with G. aggregation grew better than plants inoculated with G. mosseae. For this reason G. aggregatum was chosen for a field experiment, in which this AM fungus increased shoot dry mass, shoot length, and percent survival after transplantation. The effects of soil microorganisms on development, survival and fertility of native plants, their influence on the effects of the erosion, and their importance in plant repopulation programmes are discussed.
研究了丛枝菌根真菌（AMF）对西班牙东南部地中海气候地区常见生长的六种植物的影响。在半干旱土壤中，最常见的AMF是聚球囊霉（Glomus aggregation Schenck and Smith），其次是摩西球囊霉（Glomus mosseae (Nicol. and Gerd.) Gerd. and Trappe）。所研究的维管植物物种有粘毛白酒草（Dittrichia viscosa (L.) W. Greuter，菊科）；鸭茅（Dactylis glomerata L.）、粟草（Piptatherum miliaceum (L.) Cosson）和细叶针茅（Stipa tenacissima L.，禾本科）；圆果骆驼刺（Retama sphaerocarpa (L.) Boiss.）和小花刺金雀（Ulex parviflorus Pourret，豆科）。对豆科植物进行了单一和双重共生（根瘤菌和AMF）研究。在温室试验中，接种植物比未接种对照生长得更好，这从干重以及组织中的氮和磷含量可以看出。接种聚球囊霉的植物比接种摩西球囊霉的植物生长得更好。因此，选择聚球囊霉进行田间试验，在该试验中，这种AM真菌增加了移植后的地上部干质量、地上部长度和成活率。文中讨论了土壤微生物对本地植物发育、存活和肥力的影响，它们对侵蚀效应的影响以及在植物重新定植计划中的重要性。
