Ecco il testo (purtroppo in inglese) riguardante l'innesto tra Capparis e
una cactacea dal volume 40 n°1 2000 di Chronica
horticulturae.(pdf).fantomatica entità...
Grafting is an art of connecting two
individual plant tissues together in such a manner
that they will unite and grow as one plant. The
two individual plants may be closely related:
belonging to the same species but different
cultivars, germ plasm or clones. Interclonal grafts
are easy to accomplish because their germ plasm
are not very different. More importantly the
chromosome numbers are the same. In fruit trees
and nut crops of different clones within a species
can always be grafted together without difficulty
and produce satisfactory trees. Fro plants in
different species (inter species) but in the same
genus grafting is successful in some cases but
unsuccessful in others. Almond, apricot,
European plum and Japanese plum are grafted
successfully on peas as a root stock. In some cases
inter species reciprocal grafts are not successful.
root stock of Cactus.
A requirement for successful graft is: close
matching of callus producing tissues and criteria
for a close match of tissues is not scientifically
defined. The ability of two different plants,
grafted together, to produce a successful union, is
termed as compatibility. The opposite would be
incompatibility. The distinction between
compatible and incompatible is not defined,
therefore it is not easy to give the reason for
successful or unsuccessful graft. It is like a shot in
the dark. It may or may not hit the target.

For instance Mariana plum on peach root stock
makes a successful graft but the reverse - peach
on plum - does not work.
When the plants to be grafted are in the same
family but in different genera, the chances of a
successful graft union become more remote.
Examples of some successful grafts are: loquat on
quince roots, tomato in Jimson weed and potato
on black nightshade.
Successful grafting between plants of different
botanical families is usually impossible. Thus a
successful graft of Capparis and Cactus
theoretically falls under 'impossible'.
The union of Cactus and Capparis was made
possible with the use of Cleft grafting technique
at the Biological Science Research Laboratory of
Alcorn State University. The scions of Capparis
were inserted into the pith parenchyma of the root stock of Cactus
...etc.. mah!

Sarò sicuramente scomunicato da chi di dovere ma, non vi sembra che si
parli del sesso degli angeli?
Evidentemente molti hanno del bel tempo da perdere, e non mi si parli
di studi scientifici: proviamo a eliminare i finanziamenti, derivanti
dal risparmio sulle tasse (così avviene negli States), e vediamo se
qualcuno si mette a innestare un platano su una margherita!
Se poi consideri che con i risultati di "queste ricerche" si gira
(strapagati) mezzo pianeta per conferenze, il cerchio del businness si
chiude perfettamente.
Chi è addentro al CNR mi può capire! 
Ma forse è tutta invidia, lo confesso! 
A ribuonnatale, even later, a tutti, innesti impossibili compresi.
