Elution profile through a Sephadex G50 column of polysaccharides
in juices obtained from stalk segments of sugarcane inoculated
only with X. albilineans (circles), with G. diazotrophicus and 5 d
after with X. albilineans (up triangles) or firstly with X. albilineans
and then with G. diazotrophicus (down triangles) or simultaneously
with G. diazotrophicus and X. albilineans (squares) according to the
method described in Materials and Methods. Values are the mean of
five replicates. Vertical bars give standard error where they are larger
than the symbols.
