Observation of microbial colonization on the surface of rice roots along with their development and degradation

摘要: Abstract Microbial colonization on the surface of rice roots along with their development and degradation was examined throughout growth period plants naked eye, by light microscopy, scanning electron microscopy. Four stages were recognized in processes microbial pattern. At stage I, both crown lateral undergoing development, white, covered a mucigel layer. rarely observed. II, developed further, they stained brownish due to deposition iron oxides/hydroxides root surface. colonies commonly grooves between epidermal cells. III, ceased develop, surfaces widely deposits oxides/hydroxides. found inside exodermal cells as well IV, became dark brown or transparen...
