Effects of Host Plants on Growth and Development of Arbuscular Mycorrhizal Fungi in Rhizospere of Scutellaria baicalensis
摘要
Abstract
The effects of different host plants (Trifolium repens ,Lolium perenne ,Zea mays and Sorghum vulgare) on growth and development of arbuscular mycorrhizal (AM) fungi in the rhi-zospere of Scutellaria baicalensis were studied under sterilized conditions using pot experiment. The results showed that four kinds of plants could form symbiotic relationships with AM fungi, but the fungus characteristics and states of different host plants had significant difference. When Z.mays was used as host plant, the spore density, mycorrhizal colonization rate, succinate dehy-drogenase activity of intraradical hypha and mycorrhizal length of AM fungi were 8. 03 per gram soil,93. 33%,51. 10%,9. 67 cm, respectively. The easily extractable glomalin (EEG) and total ex-tractable glomalin (TEG) of soil were 0. 46mg/g and 1. 06 mg/g,which were higher than those of other three plants. The Z. Mays was the best host plant for the growth and development of indigenous AM fungi in the rhizosphere of S. Baicalensis. Correlation analysis showed that the spore density of AM fungi was positively correlated with the soluble sugar in host root (P<0. 05) , and TEG had positive relationship with the spore density and mycorrhizal colonization rate (P < 0. 01). The results suggested that the soluble sugar in host root greatly influenced sporulation,and TEG might be a useful index to evaluate the growth and development of AM fungi.关键词
