Yolk grafting, features and how it is performed

 

today we want to talk about yolk grafting, also known as shield grafting. But first let’s see what this issue of grafts is all about.

fruit graft consists of the union of two different pairs of plants with the aim of forming a single new plant. This is done for many reasons, including invigorating a due variety, obtaining an early production, better quality and a greater quantity, as well as adapting a new variety to the climate and soil of the place, accelerating the obtaining of the transplant material, among others.

Features of yolk grafting

The bud graft should be carried out in the months of April, May and June, by watching eye, taking into account that the yolk sprouts the same year and in July, August and September to sleeping eye, that is, that the shield grips, but that the yolk does not sprout until the following spring. The yolk graft is considered as the traditional graft of citrus and rose bushes, although it is also used very successfully in mango, peach, almond, olives and carob tree.

How yolk grafting is performed

To carry out the yolk grafting, first of all you need to cut with the grafting knife, the bark of the pattern in a smooth area and without yolk. A horizontal and a vertical cut should be made that goes from the horizontal cut down a few centimeters, making sure to form a “T”. After this it is necessary to use the grafting knife, take off the bark from both sides as if we were opening a window.

In this way the cambium is exposed, which is white and juicy. Then you must take the branch of the variety to be grafted and then with the grafting knife, cut the bark in the form of a shield, making sure that in the upper wide part, there is a good yolk with the petiole of a leaf, which must be cut to reduce the perspiration of the shield.

After this and carefully prying with the grafting knife, it is necessary to peel off the shield, making sure to avoid touching with the knife the inner part of the subject. The shield must then be left with a typical shape of a medieval shield, however, when manipulating the shield, it is necessary that we avoid touching with our fingers, the internal and juicy part, which as we have already said, is the cambium. This is the living part that grows and joins the pattern cambium and to avoid touching it, it is necessary to take the shield by the petiole.

It is worth mentioning that the buds to be inserted are selected from those branches that are more vigorous to which the leaves are cut, leaving only a part of the petiole to help manage the yolk. It should also be remembered that when the graft is glued, part of the stem of the pattern must be removed. Bending the stem contributes to the union, although later the stem of the pattern is cut and continuously the pacifiers must be removed.
