AI Technical Summary
Existing technologies lack methods to detect the increase in maize leaf cytokinin content caused by soil microorganisms with nitrifying properties through root action, which affects crop nitrogen use efficiency and food production.
A mathematical model was established to detect the contribution rate of soil microorganisms to maize leaf cytokinins using Equations 1 and 2, including the treatment and detection of the experimental and control groups. The CTK content in maize leaves was measured using enzyme-linked immunosorbent assay (ELISA). Combined with soil nitrification inhibitor and nitrate nitrogen treatment, EB and EN values were calculated to determine the contributing pathways.
This study enabled the accurate detection of CTK content in maize leaves by soil microorganisms through root action, revealing the pathways by which they regulate crop growth and promote crop growth and increased grain yield.
