From: Metabolomics reveals arbuscular mycorrhizal fungi-mediated tolerance of walnut to soil drought
Changes in plant growth performance (a), root mycorrhizal colonization (b), root mycorrhizal colonization rate (c), and shoot (d) and root (e) biomass production of Juglans regia inoculated with Diversispora spurca under well-watered and drought stress conditions. Data (means ± SD, n = 4) followed by different letters above the bars indicate significant (P < 0.05) differences. Abbreviations: DS_AMF, the treatment with drought stress and D. spurca inoculation; DS_NAMF, the treatment with drought stress and non-inoculation of D. spurca; WW_AMF, the treatment with D. spurca inoculation and well-watered; WW_NAMF, the treatment with well-watered and non-inoculation of D. spurca
