Diversity Analysis of Endophytic Actinomycetes Isolated from Sophora alopecuroides L.of Lingwu Baijitan National Nature Reserve in Ningxia
摘要
Abstract
The 288 endophytic actinomycetes were separated and cultivated from 60 samples of healthy seeds and plant of Sophora alopecuroid.es L. In six sample areas, where were sampled from different vegetations and the soil types in Lingwu Baijitan National Nature Reserve of Ningxia. Endophytic actinomycetes were classified according to their morphological characteristics. The results showed that the quantities of endophytic actinomycetes from different parts of S. Alopecuroid.es L. Were varied and there were more endophytic actinomycetes in the roots than that in the seeds and leafs for the same plant. The quantities of endophytic actinomycetes from S. Alopecuroides L. Were significantly more in sierozem than that in aeolian and the salinized sandy soil. There were the most endophytic actinomycetes from S. Alopecuroides L. In the desert steppe with xerophytic mesophytic sandy weeds than that in the other five desert steppe types. These endophytic actinomycetes from S. Alopecuroides L. In the desert steppe of Lingwu Baijitan National Nature Reserve were attributed to 11 genus. Stretomyces and Norcardia were dominant. Albacores and Greyosporus were dominant in Stretomyces.关键词
