Abstract

To determine if in a drought environment there was an adaptation for Acacia richii due to rhizobia,this experiment analyzed the accumulation of metabolites,such as proline,soluble sugar,and chlorophyll,after inoculation with SMD rhizobia separated from Tephrosia candida,YHH from Leucaena leucocephala and TWXS from A. richii under artificial drought conditions in a PEG-6000 solution. The contents of PEG-6000 were 0(control),0.010,0.025 and 0.037 respectively. Results showed that different rhizobia increased metabolite accumulation in drought conditions,but there were different levels of accumulation depending on rhizobia strains. The rhizobia SMD had a stronger potential to promote seedling resistance in a drought environment than rhizobia YHH and TWXS. Thus,it is advantageous to choose rhizobia to promote growth of A. richii in drought conditions.
