内蒙古草原几种葱属植物AM菌根侵染特性的初步研究

对内蒙古中西部草原不同生境中野生葱属植物的AM菌根侵染状况进行了调查研究。结果显示:这些野生葱属植物均被AMF侵染,多数种类侵染率较高;不同种葱属植物侵染率有差异。在不同地理环境和土壤条件下,同种葱类植物菌根侵染状况也有明显的差异。野生的葱类植物具有疆南星型(Arum type)菌根。在室内用相同的葱属植物种所进行的接种试验,所有试验植物种均被AMF侵染并形成相同的Arum菌根结构类型。

Preliminary Study on Arbuscular Mycorrhizal Infection to Several Allium Species in Inner Mongolia Grassland

A total of 11 Allium plant species from the grassland and desert of Inner Mongolia were collected and examined. All of them were infected with arbuscular mycorrhizal fungi(AMF). Most species showed a high infection rate. The infection rate was different among the different species and different in the same spices because of the varieties of the geographical environment and the soil feature. All of the Allium species form the Arum-type mycorrhizal structure. The inoculation experiment with AM fungi under the green-house condition showed that all tested spices were infected with arbuscular mycorrhizal fungi and also formed the same Arum-type mycorrhizal structure.
