Abstract Abstract：of Plasmodiophora brassicae infection on IAA and ZT contents were measured by HPLC．The result indicated that the IAA and ZT contents increased obviously after Plasmodiophora brassicae infection．The ZT contents showed the changing tendency of first rising then falling．Between 45-60 days，it was much higher than that in the healthy plant，and reached its peak about 3 times in the healthy plant at day 50．The IAA content started to rise after 55 days and reached its peak about 4 times in the healthy plant by day 70．And 85 days after infection，both IAA and ZT contents all reduced to the same level as the healthy plant.
