摘要： The selective pressure of the rhizoplane of rice plants for colonized beneficial rhizobacteria has been investigated. The rhizobacteria were isolated from the rhizoplane of rice variety Yue Guang (with a middling disease-resistant trait) and Yue Fu (with a high yield trait). The in-vitro antagonistic assay to 14 pathogens, including three major rice plant pathogens, Xanthomonas oryzae, Corticium sasakii and Piricularia oryzae Cavara, showed that the ratio of positive reactions for the strains isolated from rice variety Yue Guang were much greater than that of Yue Fu. The antagonistic spectra of those rhizoplane bacterial strains from Yue Guang were much wider than those from Yue Fu. The endophytes of rice Yue Fu plants were isolated during the whole rice-growing season in 1996. There were 10(3)-10(6) cfu/g fw (plant) of endophytes present in rice plant roots, stems and leaves. A considerable part of the endophytic population showed acetylene reduction activity and N-15(2)-fixing activity in pure culture.
