The
Benefits of Grafting
To
get plants to productivity sooner
A
better tasting, or better producing fruit tree
Contain
a too-large plant by using dwarfing rootstock
Use
a resilient rootstock in a soil that otherwise could not
To
put two varieties of the same fruit on one tree
Books
about Grafting
Reference
material:
The
Grafters Handbook – Not easy to read, not easy to find and when
found it will cost as much as $300! However, if you run across one of
these that doesn't cost $300, grab it. It has been THE manual for a
very long time and it is the only book that covers ALL – not just
the popular – grafts. The information in this book is going to be
lost soon.
The
Home Orchard, UCANR – one of the very best books that includes
notes on grafting, but presents caring for home orchards. A truly
well-written book, impeccable in it's presentation and incomparable
in the breadth and depth of grafting. Wonderfully written.
A
Grafting Glossary
Adventitious
- said of buds, shoots or roots arising out of order; not initiated
by apical meristems
Apical
Meristem -the
growth region in plants found within the root tips and the tips of
the new shoots and leaves, a mature cork cell is non-living and has
cell
walls
that are composed of a waxy substance that is highly impermeable to
gases and water
Bark
– the outer layers of the rind, consisting largely of cork, serving
to protect the inner rind and cambium. See rind.
Bud
– to insert an eye, or bud, when bud-grafting
Bud
grafting – grafting with an single eye or bud, detached from a
shoot along with a portion of rind and, in some cases a small slice
of the wood
Callus
– healing tissue arising from the cambium at wounds
Cambium
– the layer of meristematic tissue between the wood and the rind
from which further elements of both develop
Clone
– vegetative progeny of one plant
Compatible
– said of plants which when grafted together form a good, sound and
permanent union
Cultivar
– internationally agreed technical term for what, in English, is
known as a variety .
Eye
– a single bud or group of buds
Graft
– where the scion meets the stock, the completed operation of
grafting, the union, a term often wrongly used for scion
Graft
– to prepare and place together plant parts so that they may grow
together
Incompatible
– said of plants which when garfted together fail to form a lasting
union
Meristem
– tissue capable of growth, either primary from which new organs
develop (primordial of leaves, stems, roots) or secondary, by which
special tissues (cambium, phellogen)
Meristematic
– pertaining to meristems
Mother
Tree – a tree selected as a source of scions, cuttings or seed
Petiole
– leaf-stalk
Phellogen
– meristematic cork producing tissue in the outer region of the
rind
Rind
– all the tissues external to the woody core of stems and roots,
often termed bark
Rootstock
– root-bearing plant on which the scion is grafted.
Scion
– part of plant used for grafting upon the stock plant
Tissue
– the substance, structure or texture of which the plant body, or
any organ of it, is composed
Xylem
– botanical name for wood
Safety
First!
Before
you begin to graft, think about your safety first. The knives you are
working with are – or should be – very sharp. Keep that thought
first in your mind. Always cut away from yourself, never towards
yourself – this is the root of most accidents. We are trying to get
a knife through some stubborn material and without a second thought,
turn the knife towards our fingers without even thinking. Know where
the first aid kit is and, if necessary, the closest emergency room.
Grafting
Tools/Supplies
Essential
Tools:
1
Knife exclusively for grafting cuts, many sizes and shapes, don't go
cheap on this knife.
A
means to sharpen that knife at the bench or in the wild (of course
you could have two knives, one for bench work and one for field work,
the only concern is that you have the means to keep them sharp!)
Sharpening
devices – whatever cranks your tractor and helps you keep your
blades sharp (you are more likely to be injured by a dull blade than
a sharp one)
Some
way to make the graft stable – Parafilm is the hot tip! Rubber
bands are a pain
A
small first aid kit. I am serious. And brush up on your ability to do
first aid.
In
teaching grafting, it proved important to keep students in pairs.
Person A watches as Person B works with the knife and they switch.
For your first few grafts, have a friend or fellow student watch you
and then switch and you watch them.
