Ceriporia lacerata HG2011 enhances P mobilization and wheat agronomic performance irrespective of P fertilization levels.

AIMS

To identify soil phosphorus (P) mobilization and wheat agronomic performance in response to the P mobilizer Ceriporia lacerata HG2011 could provide a new strategy for improving fertilizer P efficiency in wheat cultivation.

METHODS AND RESULTS

Liquid culture showed that C. lacerata HG2011 converted Ca (PO ) , FePO , AlPO , phytate, lecithin and ribonucleic acid into soluble inorganic P, which was stimulated by ammonium and urea but less influenced by P supply. In the incubation experiment, this fungus colonized on wheat roots, and mobilized P in the soils regardless of Olsen P levels. The efflux of protons, organic acids and phosphatase could be involved in insoluble P mobilization. In the greenhouse pot experiment, C. lacerata HG2011 increased soil Olsen P under different P fertilization levels, improved wheat P uptake by 15.39%-28.70%, P fertilizer use efficiency by 4.26%-13.04% and grain yield by 12.24%-22.39%.

CONCLUSIONS

Ceriporia lacerata HG2011 was able to colonize on wheat roots, mobilize P in soils and improve wheat agronomic performance irrespective of P fertilization levels.

SIGNIFICANCE AND IMPACT OF THE STUDY

Ceriporia lacerata HG2011 could be used to enhance the quality of compost or as a bio-fertilizer for P mobilization in modern sustainable agriculture.
