\section{RESULTS}  \subsection{Environmental isolates are pathogenic toward experimental hosts}  We analyzed the virulence of 18 \textit{S. maltophilia} isolates in two different experimental host systems. The first  The growth promotion potential of S. maltophilia isolates on canola seedlings under normal growing condition. In order to determine the potential of S. maltophilia isolates to promote growth in canola, 4 day old canola seedlings were inoculated overnight with bacterial cultures suspended in sterile distilled water. Percentage changes of the median in parameters measured were determined using the no bacterial control median as the initial and the isolate medians as the final under both stress and non-stress conditions.   No significant differences were observed in number of root branches and root length in canola plants exposed to bacterial isolates relative to the “no bacterial” control (Figs. 1 & 2). Stem length of canola plants, however, was significantly (P < 0.05) lower in canola seedlings inoculated with isolate CDC 92-03-30, ATCC 17666, CDC 98-43-10, CDC 2013-11-01 and CDC 2011-09-42 than the “no bacterial” isolate (Fig. 3).
