Scion - A shoot or sucker growing from a mature plant, generally used for grafting purpose.
Sclereid - An irregular sclerenchyma cell found in the parenchyma of some plants, in nutshells, and seed coats.
Scion- An aerial plant part, often a branchlet, that is grafted onto the root-bearing part of another plant.
scion. The portion above a graft that becomes the trunk, branch, and tree top; the cultivar or variety.
sclerotium (plural: sclerotia). A compact mass of hardened mycelium that serves as a dormant stage in some fungi.
SCION - A suitable piece that is a desirable specimen of a woody plant, used in grafting.
SCOOPING (de-eyeing) - A technique that is used to produce a shorter and bushier plant by scraping out the center eye of the bulb.
scion A cutting or bud that is grafted to the stock of another plant.
secondary growth The growth resulting from the activities of lateral meristems (vascular and cork cambium).
The scion:
This is the selected part which produces the desired fruit or flowers on the mature plant. Scion varieties are refered to as clones and are usually named for easy reference such as apple 'Gala' or plum 'Burbank'.
Scions are those shoots which, united with the stock, form the graft. They should be gathered several weeks before the season for grafting arrives, It is desirable that the sap of the stock should be in brisk motion at the time of grafting; ...
Scions are lengths of year-old stems you collect from trees you wish to propagate or preserve. Many deciduous tree varieties, especially fruit trees, are propagated by grafting.

SCION: The upper part of the union of a graft.
SCOOPING (de-eyeing): A technique that is used to produce a shorter and bushier plant by scraping out the center eye of the bulb.
SEEDHEAD: Dried, inedible fruit that contains seeds.
The scion, which is the plant that you want to reproduce, is first prepared as a wedge, or jagged wedge matching the slit in the rootstock and inserted and bound tightly.
All trees in plantings between three and ten years of age grown on susceptible rootstocks should be observed for delayed bud break, leaf and bark discoloration, and twig dieback that are characteristic of the collar rot symptoms on the scion.
Most fruit-bearing plants are grafted and composed of two important, yet separate, plants: the rootstock (below the soil) and the scion (above the soil).
Whether this union occurs depends partly on the basic compatability of the scion and the rootstock.
Warm winter areas should plant with the bud union (the swollen joint between the root stock and the scion or grafted cane) 1" above soil level, ...
GRAFTING is just a method to connect the sap-flow of the rootstock to that of the scion and it doesn't need much. I've seen all sorts of funny results with only a fraction of the cambium sap layers making connection but the plant still thrives.
Grafting involves the use of a scion having two or more buds. There are numerous types of grafts including whip, cleft, bridge, in arch, stump, side, inlay bark, approach and others.
The top part is called the scion, and is a branch cutting that has been taken from the variety of fruit you want to grow. The bottom part is the rootstock, and it is usually selected either for hardiness or the ultimate height and size of the tree.
The process of joining a desirable stem or bud of one plant (known as the scion) on to the less desirable, but hardier, stem of another (known as the stock). This will give a stronger root system than the scion would have normally had.
Time and again, I have observed suckering (vigorous growth from roots) and incompatibility between rootstock and scion. You can recognize suckers by their origin from the base of the plant.
The point where rootstock and scion join is the 'union' (a bulge in the stem.) To prevent the scion rooting, plant with the union 15cm (6in) above soil level. This will keep any mulch/compost away from the immediate trunk.
You should know if the variety has been grafted, because if the scion (top) dies, the undesirable rootstock will take over and the tree will be useless.
The gardens were founded by John Morris, scion of the I.P. Morris iron-manufacturing family, with his sister Lydia. Started in 1887, the Morris siblings cultivated the grounds of their estate and dedicated it to horticulture and education.
When you plant the tree, be sure the "bud union," where the scion meets the rootstock, is roughly 2 to 3 inches above ground level. Water and gently tamp the soil as you replace the dirt around the rootball; this will remove any air pockets.
However, most rootstock infections are not associated with suckers, and it appears that many develop when bacteria move systemically from scion infections down into the rootstock. The factors that influence this systemic movement are unknown.
