My own "studies on mice" have shown that already mature Lophophora williamsii grafted to either Myrtillocactus geometrizans or Stenocereus pruinosus are very much active. A good study would be to use obviously immature plants, such as 6 month Pereskiopsis grafts and dry them.

Those are Pereskiopsis cacti which the Lophophora are grafted upon.

An easily cultivated, fast growing epiphyte or lithophytic plant. Needs a compost containing plenty of humus and sufficient moisture in summer. Should not be kept under 5ºC (41ºF) in winter. Perform best if grown in full sun. Extra light in the early spring will stimulate budding. Flowers in late spring or early summer, only blooms one night a year.

the point i was trying to make is that alk's *seem* to be produced in the stem, and don't really move around much. many plants either produce and/or store the alk's in the roots. it *seems* not so with many cacti. this translates to grafted cacti will still produce mescaline (this is not proven so don't think it is ). If this is true, the grafting stock should not matter at all, cause the roots would *THEORETICALLY* not be that important for alkaloid production i mentioned the stocks above because it should be mentioned which species have been used

in short, again theoretically, there probably isn't any difference between root stocks used.

hope that helps

works quite well to boot. cacti, as the theory goes, can all be grafted together.

anyone ever had the idea to graft pereskiopsis onto itself to form a bi-level pyramid of pyramids and then where the top four grafts meet to put a bunch of bridgesii pups?

In Adam Gottliebs 'Peyote and other psychoactive cacti'....

for alkaloid content of grafted vs non grafted I have read in the above mentioned book that alkaloid content will not increase at the same rate as growth and that it needs to be re rooted and left for a year for levels to balance out.

If what I wrote above is true, then pyramiding is pointless. It would look spectacular those pyramids, though!

Peyote Cultivation-

1) Obtain Lophophora williamsii = "Peyote" seeds.

2) Sow the seeds and grow the seedlings in a humid enviroment for six months to one year (6 months - 1 year) SLOWLY "hardening then off" to a fairly dry enviroment.

3) Grow the seedlings as quickly as possible until they flower (grafting is ok at this stage). Allow them to flower for two or three (2-3) years, thus producing many seeds.

4) The cacti should all be on their own roots now. Begin "hard growth" to increase potency for three to seven (2-5) years. Grow the cacti under fairly harsh conditions.

5) After the Peyote cactus is five to thirteen (5-13) years past flowering age and has been "hard grown" for a number of years, it may be harvested following the proper method ensuring some areoles are left to produce new "Pups" or "Crowns".

The total process should take anywhere from 5-25 years if you start with seed, some say you can have ready to eat Peyote in 3 years if you graft! It's worth the wait.
