摘要：We observed the effects of Emmia lacerata strain SR-5 on the growth of two Michelia macclurei clones (clone-411 and clone-425) and analyzed their similarities and differences. Here, we evaluated the growth-promoting effect of E. lacerata on M. macclurei, a native tree species of subtropical China. Clonal plantlets of M. macclurei (clone-411 and clone-425) were inoculated with E. lacerata strain SR5, and the growth of the plantlets was recorded continuously for 6 months. The effects of strain SR5 on the two M. macclurei genotypes were evaluated by measuring physiological responses, nutrient uptake, and soil microbial community structure. Growth parameters and biomass of M. macclurei plantlets were significantly enhanced by SR5 inoculation. Scanning analysis of roots and leaves showed that their growth was promoted. Interestingly, the growth-promoting effect of SR5 was more significant on clone-411 than on clone-425. Based on the characteristics of both soil and plantlets, we speculated that the specific growth-promoting mechanisms of SR5 differed between the two M. macclurei clones. SR5 appeared to promote growth of clone-411 mainly by promoting nutrient absorption, whereas its effect on clone-425 may have been mediated through plant growth hormone production. Comparing the effects of strain SR5 on two clones provides insight into key factors in the process of strain-plant interaction and can promote the development of biofertilizer.
