Introduction Rice ( Oryza sativa L. ) is a pivotal cereal crop worldwide. It relies heavily on the presence of iron plaque its root surfaces for optimal growth and enhanced stress resistance across diverse environmental conditions. Method To study crystallographic aspects formation rice roots, concentrations Fe 2+ PO 4 3- were controlled in this study. The effects these treatments assessed through comprehensive analyzes encompassing status, surface concentration, vitality, enzyme activities, microstructural characteristics using advanced techniques such as analysis, scanning electron microscopy (SEM), ultrathin section transmission (TEM). Results results demonstrated that an increase concentration or decrease nutrient solution led to improvements various indicators. There was elevation DCB (dithionite-citrate–bicarbonate) content within significant activities superoxide dismutase (SOD), peroxidase (POD) catalase (CAT) enzymes. Moreover, increased, amorphous oxide minerals gradually transformed into ferrihydrite particles with sizes approximately 200 nm goethite 5 μm. This showed substantial surfaces. noteworthy there distinct gap ranging from 0.5 3 μm between formed treatment cellular layer surface. Discussion elucidated impacts formation, structure, morphology while discerning variations spatial proximity under different
