Abstract:
Poa praterrisis L.and Lolium perenne L.commonly used in the northern region were used as plant experimental materials，and different concentrations of endophytic agents were applied.The concentration gradient was T1 of 10%，T2 of 30%，T3 of 50%，and T0 was the blank control group without the application of bacteria，which was used as the experimental treatment.The inoculum was applied by seed dressing，and the infection was detected after 60 days of normal maintenance.The root activity，relative conductivity，soluble protein，soluble sugar and chlorophyll content of plants under different inoculum concentrations were measured.The effects of different concentrations of microbial agents on P.praterrisis L.and L.perenne L.were studied，in order to screen out the optimal concentration of microbial agents and improve the growth quality of plants.The results showed that the infection effect was the best when the concentration of the agent was 50% in the tested plant materials.The infection rate of P.praterrisis L.and L.perenne L.could reach 38.71% and 46.73%,respectively.The root activity of P.praterrisis L.increased to 13.22%,the conductivity decreased to 14%,the soluble protein content reached 2.91 mg·g-1,the soluble sugar content reached 28.84 mg·g-1,and the chlorophyll content reached 3.10 mg·g-1.The root activity of L.perenne L.increased to 114.42%,the conductivity decreased to 11.00%,the soluble protein content reached 3.51 mg·g-1,the soluble sugar content reached 27.28 mg·g-1,and the chlorophyll content reached 3.22 mg·g-1.The comprehensive conclusion shows that the application of 50% concentration of bacterial agent could effectively improve the growth quality of the tested plant materials.
