When worked at the top of a stem formed of the stock, the growth from the graft or bud must be pruned in a similar way.
This species is frequently used as a stock on which to graft other Cacti.
Grafting, however, has not been found to answer the purpose, since the stock and the graft have been found to retain their respective alkaloids in the natural proportion just as if growing separately.
Other race mixtures consist of the zambos (the African-Indian cross), an Asiatic graft upon these various crosses, and an extremely confusing intermixture of the various crosses, for which the Spanish races have descriptive appellations.
Harrarese is "a Semitic graft inserted into an indigenous stock" (Sir R.
Some of the American varieties have been introduced into France and other countries infested with Phylloxera, to serve as stocks on which to graft the better kinds of European vines, because their roots, though perhaps equally subject to the attacks of the insects, do not suffer so much injury from them as the European species.
Grafting or " working " consists in the transfer of a branch, the " graft " or " scion," from one plant to another, which latter is termed the " stock."
Here the graft is fixed to the side of the stock, which is planted or potted close to the plant to be worked.
An artistic taste will recognize the essential differences, and not endeavour, apart from questions of strength, to graft a design suitable for one on another.
Some quantity of cutch is exported, as also stick-lac, which the Red Karens graft so as to foster the production.
The parts are, however, sometimes so small that the tongue of the graft is dispensed with, and the two stems simply pared smooth and bound together.
This is effected by raising up a small mound of rich compost around it, a contrivance which induces the graft to emit roots into the surface soil.
From a careful series of experiments made in the Horticultural Society's Garden at Chiswick, it was found that where the soil is loamy, or light and slightly enriched with decayed vegetable matter, the apple succeeds best on the doucin stock, and the pear on the quince; and where it is chalky it is preferable to graft the apple on the crab, and the pear on the wild pear.
Among gardeners the general opinion is against the possibility of graft-hybridization.
In a soil, for example, naturally moist, it is proper to graft pears on the quince, because this plant not only thrives in such a soil, but serves to check the luxuriance thereby produced.
Side-grafting is performed like whip-grafting, the graft being inserted on the side of a branch and not at the cut end of the stock.
In this case the scion is grafted directly on to a portion of the root of some appropriate stock, both graft and stock being usually very small; the grafted root is then potted so as to cover the point of junction with the soil, and is plunged in the bed of the propagating house, where it gets the slight stimulus of a gentle bottom heat.
In selecting young pear trees for walls or espaliers, some persons prefer plants one year old from the graft, but trees two or three years trained are equally good.
The chief wealth of the Arab tribes of the plateaus consists in their immense flocks of sheep. The horses and mules of Algeria are noted; and the native cattle are an excellent stock on which to graft the better European varieties.
We may hence infer that C. purpureus was grafted or budded on the common laburnum, and that the intermediate forms are the result of graft-hybridization.
