THE SCIENTIFIC RESEARCH PROGRAM
Lophophora williamsii showing good harvesting
technique
Peyote post-harvest regrowth –
Reharvest of regrowth after 2 years
PNF – Plant not found.
TNF – Tag not found.
nd – No data available.
– – Missing
data.
Two years following the initial harvesting the survivors of our harvest
group were divided into two parts and all new growth was reharvested
from half of them.
Images of the tags can be viewed via
the links for the tag numbers and images of the actual plants that were
harvested in our study can be viewed using the links in the column
headed "Regrowth as number of pups". Images of the reharvested group
can be found in the far right column.
Plant No.
