Graft of lateral subcortical stake

 

I put as example several stake grafts or prongs of female pistachio on pistachio born of seed.

 

This method can be used successfully in the following trees of caducous leaf from half-full of the Winter to end of the Spring, depending on the species, since it needs that the host is beginning to already wake up of the winter lethargy and its crust takeoff with facility:

 

-Pistachio.

-Almond tree.

-Peach tree.

-Plum tree.

-Cherry tree.

-Alpricot.

-European medlar tree (Mespilus germanica).

-Quince.

-Apple tree.

-Pomegranate tree.

-Khaki.

 

In trees of perennial leaf it is equal of successful, but the graft must be covered with a bag of plastic:

 

-Medlar of Japan.

-All the species of citruses.

-Avocado.

-Mango.

-The trees of caducous leaf in the heat of vegetation, even in Summer.

-Some ornamental coniferous: Juniperus, Thuia

 

In the first place a cut in T in a smooth zone of the crust of the host is made with the knife to graft. With care and helping yourself with the separator of the knife to graft, the crust is taken off as if a window was opened.

The stake to graft is reduced in bevel by a single side.

Not bevelled side of the stake.

The stake by the bevelled side is introduced underneath the raised crust of the host.

It is not necessary to introduce the stake under both sides of the raised crust, is sufficient that it is introduced  in one of the two sides. The result is the same one, since most important it is to intimately contact the bevelled part of the stake with the subcortical cambium of the host.

In this case it is left a bud introduced, which is an advantage in case, once taken hold and brought forth the graft, the wind breaks the graft. If it is left the part introduced, the bud can bring forth and save the graft.

 Next the graft is tied strongly with raphia to graft.

 

The union with mastic to graft is smeared.

Here two subcortical lateral grafts are seen on different levels in the same branch from pistachio tree.

 

And the lateral subcortical grafts are already made. This type of graft is a variant of graft of lateral Crack, modified by me, changing the cut of host in form of tongue-piece by the cut in T of the crust, equal to cuts of graft of small shield, but changing the small shield by a stake.

 

This type of graft can be done in all the trees and shrubs, as much of caducous  like perennial leaf, with the reservation of which in those of perennial leaf the stake is replaced by little branch with leaves and the graft  is covered with plastic transparency bag during several weeks, so that it does not dehydrate. Another circumstance to consider is that the host must be on the verge of waking up of the hibernation, to be able to take off the crust with facility.

 

 

And here have you the result, spent about two months. After bringing forth the bud of the stake, I have cut the superior part of the host, so that all the sap goes to the graft and grows vigorous. Two weeks passed, I will clear the fastening of raphia, so that this one does not strangle to the graft, making difficult the passage of the sap.
