中文摘要	采用分室培养方法研究接种幼套球囊霉(Glomus etunicatum, BEG168)、摩西球囊霉(G. mosseae, BEG167)、混合菌剂(M)对两种沙漠早春短命植物小车前(Plantago minuta)和尖喙(牜龙)牛儿苗(Erodium oxyrrhychum)生长发育及矿质养分吸收的影响.结果表明,接种AMF处理的小车前和尖喙(牜龙)牛儿苗根系形成了典型的菌根结构,侵染率为22%-60%;接种AMF提高了小车前和尖喙(牜龙)牛儿苗两种植物的生物量、株高及N、P养分吸收量.小车前单独接种BEG167、BEG168以及混合接种都显著提高了单株种子数量,其增幅分别为67%、50%和78%.上述结果说明,在极端贫瘠和干旱的古尔班通古特沙漠中,丛枝菌根真菌对于早春短命植物小车前和尖喙(牜龙)牛儿苗的生态适应性的贡献表现为促进营养生长、提高后代(种子)繁殖数量.
英文摘要	Aims We investigated the effects of arbuscular mycorrhizal fungal (AMF) inoculation on growth and nutrient uptake in Plantago minuta and Erodium oxyrrhynchum, the most important ephemeral plants in Junggar Basin desert.Methods We inoculated with two AM fungi, Glomus etunicatum (BEG168) and G. mosseae (BEG167), as well as mixture of both species (M). Important findings Mycorrhizal colonization rates were 22%-60% and typical mycorrhizal structures were formed. Inoculation of both AM fungi improved plant vegetative growth by increasing biomass and plant height. Both plant species had significantly increased N and P concentrations. Seed number per potted plant of P. minuta inoculated with both AM fungi separately and together was significantly higher by 67%, 50% and 78%, respectively, than in non-inoculated plants. We conclude that AM fungi enhanced the two spring ephemeral plants in the extreme dry, nutrient-poor desert environments by improving N and P uptake and increasing seed number, which is important for maintaining populations.
