Effects of indigenous soil cyanobacteria on seed germination and seedling growth of arid species used in restoration

摘要

Background and aims Cyanobacteria from biocrusts can enhance soil function and structure, a critical objective when restoring degraded dryland ecosystems. Large-scale restoration of biodiversity requires direct seeding of native plant species, and bio-priming seeds with cyanobacteria is a potential method of initiating enhanced soil functioning. The utility of cyanobacteria for improving soil is therefore dependent on whether target plant species remain unaffected during its application.
