Abstract

Abstract: The changes of rhizosphere microbial populations of grafted eggplants with different rootstocks and cropping systems were studied. The results showed that the populations of rhizosphere actinomyces and fungi of grafted eggplants increased; and that bacterial populations decreased. A /F increased and B /F decreased. In addition, the total rhizosphere microbial numbers of grafted eggp lants increased. In both rotation cropping and monoculture cropping, rhizosphere actinomyces populations of grafted eggplants were significantly higher than those of the control at 0.01 level, but bacterial populations of the controlwere significantly higher than those of grafted eggplants at 0.01 level. In monoculture cropp ing, the ratio of rhizosphere bacteria and actinomyces of eggplants decreased, and that of fungi increased.

Key words: Graft, Eggplant, Rhizosphere microorganism
