摘要
1994～1997年,先后从山东省主要花生产区临沂、烟台等地采集约1000株不同类型的花生无病株,进行了植株内主要微生物类群分析。结果表明,不同品种花生的内生菌都有细菌和真菌,未分离到放线菌和酵母菌。细菌以芽孢杆菌(Bacillus spp.)、黄单孢菌(Xanthomonas spp.)和欧文氏菌(Erwinia spp.)为优势种群。其中芽孢杆菌属以巨大芽孢杆菌(B.megaterium)、蜡样芽孢杆菌(B.cereus)和枯草芽孢杆菌(B.subtilis)3种为主,表现在品种间分布广、带菌量高、持续时间长。真菌以丛梗孢菌(Monilia spp.)、链格孢菌(Alternaria spp.)为主。其它种类的内生细菌和真菌在不同品种、不同生育期以及不同地区之间都存在程度不同的差异。
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.
