摘要:对甘肃盐碱土中植物的VA菌根真菌共生状况进行研究,结果表明:在10科17种植物中,除碱蓬(Suaedaglauca Beg.)外均被菌根真菌侵染,占94.1%;盐碱土中孢子密度较高,表明甘肃盐碱土生态系统中植物对菌根真菌具有较高的依赖性,菌根真菌在盐碱土中产孢能力较强;所调查植物的VA菌根结构类型Arum型占68.75%,Pris型占31.25%;菌根结构类型与宿主植物类型有关,禾本科(Poaceae)和鸢尾科(Iridaceae)植物为P型菌根,百合科(Liliaceae)、胡颓子科(Elaeagnaceae)等其它科植物均为A型菌根;土壤类型影响了宿主植物的菌根侵染率和根际土的孢子密度,相同宿主植物在不同类型土壤中的菌根侵染率和孢子密度具有很大的差异.
The symbiosis of plants with VA mycorrhizal fungi in saline-alkali soil of Gansu was studied and this showed that the VA mycorrhizal fungi colonized all 17 species of 10 families but Suaeda glauca Beg. and the colonization rate was 94. 1% ;there was high spore density of the mycorrhizal fungi in saline-alkali soil,indicating that the plants relatively highly relied on the mycorrhizal fungi in saline-alkali soil ecosystem of Gansu and the mycorrhizal fungi had a strong capacity of producing spores in the saline-alkali soil; of the VA mycorrhizal fungi that was investigated to infect plants,Arum type accounted for 68. 75% and Pris type accounted 31.25% ;the types of the mycorrhizal fungi depended on the types of their host families, Poaceae and Iridaceae supporting P type and other families such as Liliaceae and Elaeagnaceae supporting A type; soil types exerted influence on the colonization rates and rhizospere spore densities of host plants and the colonization rate and rhizoshpere spore density of same host plants greatly differed among different soil types.
