Energy dispersive X-ray microanalysis was used to determine elemental distribution of P and Ca in mycorrhizal and non-mycorrhizal cucumber roots. X-Ray microanalytical investigations revealed P contents was mainly detected in the arbuscular cytoplasm, and accumulated in poly phosphate granules, while the content in the arbuscular interface was significantly lower compared to those of the other cell compartments. High Ca content was detected in interfacial apoplast and cell wall compartments, while cytoplasmic contents in cells were lower.
