Rhizosphere phosphorus fractions controlled through P fertilization influence wheat infection by Heterodera avenae.

ABSTRACT:

Background

Heterodera avenae (cereal cyst nematode, CCN) infects wheat and causes severe yield losses. CCN infestations can be decreased by applying phosphate fertilizer in wheat fields, but the underlying mechanisms are still largely unclear.

Results

In this study, the relationships among CCN, wheat root morphological traits, soil P fractions, and soil phosphatase activity in the rhizosphere were investigated with single superphosphate (SSP), monoammonium phosphate (MAP), diammonium phosphate (DAP), and ammonium polyphosphate (APP) application and without phosphate fertilizer (CK) application. APP most effectively inhibited the occurrence of CCN, with the number of cysts decreasing by 48.8%, and was decreased by 31.6%, 33.9%, and 16.4% in SSP, MAP, and DAP treatments, respe
