The cells of soft rot bacterium,Erwinia carotovora subsp,carotovora,were washedwith two methods to remove their extracellular saccharide(EPS)and lipopolysaccharide(LPS)and then inoculated to roots of Chinese cabbage seedlings,for testifying their adsorption on rootcells and root hairs.The bacterial numbers adsorbed irreversibly were detected,and ranged from3.63×10~7 CFU·g~(-1) to 1.32×10~8CFU·g~(-1) on ro(?)t cells and from 70bac.cm·cm~(-2) to 600bac·(?)m~(-2)on root hairs when the intact(unwashed,and EPS-a...
