Like I said, I've been out of this arena for a few years (guess
it's about 2005 now, lol) <br>
<br>
Looks like research is suggesting a correlation between genetics
and chemical activity.<br>

<i>The close correspondence between chemotype and genetic cluster
provides the first DNA-based evidence for the genetic basis of
ginsenoside composition</i><br>

<i>Chemotype did not vary by production type (wild versus
cultivated) and roots within a population rarely exhibited
chemotypes different from the overall population chemotype.
These results provide support for recent evidence that relative
Rg1 to Re ginsenoside contents in American ginseng roots vary by
region and that these differences are likely influenced more by
genotype than environmental factors</i><br>
<br>
A great argument for growers to use local seed. <br>
<br>
Curious how the longer growing time of wild relates to
ginsenocides (I thought some occurred only after 5 years, while
industrially grown roots are grown shorter times than wild sim or
wild) but regardless, it's a good excuse to encourage growers and
push FWS to work on sustainable seed supply.<br>
