| Abstract: | About 1000 symptomless peanut plants were collected for the analysis of peanut endophytes from the fields located in different main cultivation regions of peanut in Shandong Province from 1994 -1997. Both bacteria and fungi were isolated from four different typical cultivars of peanut by traditional methods. The main groups of peanut endophytes were very similar with all cultivars tested. Bacillus spp. , Xanthomonas spp. , Erwtnia spp. occurred at a higher frequency that others. They were therefore considered as the dominant genera of endophytic bacteria in peanut plants. In addition, endophytic Bacillus spp. included three species, which were B. segaterium, B. cereus and B. subtilis. Endophytic fungi , such as Monilia spp. and Alternaria spp. , were the main groups in peanut plants. There were many significant differences on the population and dynamics of other endophytes between different peanut cultivars, growth periods and cultivar regions. |
