[Research on cause of distinction in antiendotoxic activation of radix isatidis from different cultivated populations].
OBJECTIVE
To research into the cause of distinction in antiendotoxic activation of Radix Isatidis from different cultivated populations.


METHODS
19 samples of Radix Isatidis were gathered. 12 portions of seeds were cultivated in the same field in Shanghai, and the selected and artificially bred autotetraploid seeds were planted in 5 different locations. All the samples were compared through antiendotoxic experiment.


RESULTS
There are some marked distinction among the 19 samples from different populations. The distinction of the 12 samples cultivated in the same field didn't disappear. The activation of autotetraploid from 5 different locations didn't vary on the whole.


CONCLUSIONS
Germplasm is the main factor to cause activation distinctions of Radix Isatidis, while environment is less important.
