THE SCIENTIFIC RESEARCH PROGRAM
Lophophora williamsii showing a cut and
oxidizing surface
Peyote post-harvest regrowth –
Second reharvest of regrowth after 2
years
nd – No data
available.
– – Missing
data.
Two years following the initial harvesting the
survivors of our harvest group had been divided into two parts and all
new
growth was then reharvested from half of them.
Now, two years later at the four year point, we
again divided the survivors showing regrowth into two groups and
reharvested
half of those. Both sets conveniently had four dead/missing plants.
Weights listed are for the original
plant crown weight and the weights for the total of the reharvested
crowns.
Images of the regrowth on the actual
plants in our
study can be viewed using the links in the column headed "Regrowth as
number of pups".
Images of the reharvested group and
the new controls can
be found in the
far right "Comments" column.
Images of the
harvested peyote crowns offered for
sale by a licensed distributor.
