Fig. 7From: Earthworms facilitated pepper (Capsicum annuum L.) growth via enhancing the population and function of arbuscular mycorrhizal fungi in a low-density polyethylene-contaminated soilShoot and root P concentration (A), root-to-shoot P translocation efficiency (B), fruit P concentration (C), and total P acquisition (D) of pepper in the sterilized soil. Control, non-inoculation; E, inoculation of earthworm; M, inoculation of arbuscular mycorrhizal (AM) fungus; E + M: inoculation of both. Data are means with standard deviation (n = 4). Different letters indicate significant difference (p < 0.05)Back to article page
