3.1 Effects of soil microorganisms onN. tabacumfitness
Variation and development of soil microbiomes exert distinct effects onN. tabacumfitness. As shown in Figure 1a,
soil
sterilization treatment prior to sowing significantly decreased biomass
accumulation when plants grew in FS (p < 0.05), but not
if grown in CCS (p = 0.94). In addition, no significant
difference was found in biomass allocation patterns in N.
tabacum , with one exception: soil
sterilization
treatment prior to sowing markedly
decreased leaf mass when plants were grown in FS (Figure 1b).
Specifically, the LMA of N.
tabacum plants grown in F_S were significantly higher than those grown
in F_NS (Figure 1c).
