METABOLIC STABILITY OF PHYTOPHTHORA-CINNAMOMI RANDS IN WESTERN AUSTRALIA

Abstract

Ten isolates of Phytophthora cinnamomi Rands from Western Australia were tested for metabolic variation using a commercial miniaturized biochemical system developed for bacteriology. The isolates included the two mating strains, and had been maintained in the laboratory for various times. The isolates were tested before and after repeated passaging on solid media. Statistical analysis of the biochemical results showed no major differences between the isolates, and for the most part they appear to be stable in cultivation. However, there were small passage effects on some of the media, particularly with glucose utilization.
