3.  A scion is a piece of vegetative material
taken from a tree that produces the fruit
variety you want to graft.
 OR
 Scion is a upper portion of grafted plant

4.  ONE YEAR WOOD
 TIMING
 SIZE AND SHAPE
 LABEL
 STORAGE

6. When selecting scion wood you want
to find last year’s growth, ideally
shoots that are about pencil thick.
Find one year wood by following a
new growth branch tip down
towards the older wood until you
find a growth scar.

7. Scion wood should be cut in late
winter or early spring when your
tree is dormant, that is, not in
active growth and before bud-burst
Fruit trees are dormant through the
winter months, so material can be
collected any time until about
February.
The best time to cut your scion is
just before you graft with it as scion
wood can lose its vitality as it dries
out over time.

8.  The size, shape and number of scion wood
twigs you collect is going to depend on
what you are using them for.
 Having the rootstock and scion material
the same thickness enables more cambial
contact so increases the likelihood and
strength of your graft join.
 depending on the length of new growth on
your tree, you may be able to graft
several new trees from each scion.

9. After cutting the scions, it is
important to bundle them up and
label before storing them. Even with
the worlds best intentions, it is easy
to forget which bundle is which
variety or which tree it came from.

10.  Mother plants of the variety should be
genetically true to type.
 The plants should be healthy and free
from any diseases, pest infestations and
physiological disorder.
 The plants should have known pedigree
records regarding bearing potential, fruit
quality and problems, if any.
 The plants should be precocious and
prolific bearer.

11.  Preparation of scion
material of fruit crops

12. VARIETY : ALPHANSO
Selection and preparation of scion bud wood.
A 3 to 6 month old terminal bud wood having 4
to 6 mm thickness and 10-20 cm
length is selected from a desired variety, which
is free from pest and diseases and vigorous in
growth. All the leaves are removed from such
selected branch. Keeping 5 to 10 mm petiole
attached to it.

13. This branch should be allowed to
remain as such on the tree at least 8
to 10 days prior to grafting.
The drop of these petioles and
swelling of terminal buds is a good
judgment of preparation of scion
wood.
The usable life of scion bud wood is
2 to 3 days when packed in a wet
cloth placed in polythene bag

15. VARIETY : NAGPUR SANTRA
Preparation of scions :
 Scion wood may be collected at any time
of the year when a mature flush is
present on the source tree and suitable
rootstocks are available. The best times
for budding citrus are late summer and
early autumn or spring.
 The most suitable material for budding is
found on the centre third of a shoot with
rounded wood. Triangular wood may be
used where material is limited.

17. VARIETY :thompson seedless
Prepartion of scions :
 The scion cuttings selected should be one
season old and matured having better pith.
 The scion cuttings should preferably be selected
from the middle portion of the straight canes on
the vine.
 The scion material selected should be from
healthy, disease and insect free vine.
 It should be fully matured with diameter of at
least 0.8 cm.
 Immediately after cutting grafting is to be done.

18. Selection and
cutting of scion
of desirable
variety
Cuttings
with 2-3
buds

19. Grafting in
grape
Plant grow after
successful union

20. The budstick is a twig, usually from the
current season's growth. It is taken from
the plant of the desirable variety to be
increased. It should have average vigor, be
healthy and have plump, well-developed
buds. Buds on the center of the twig are
generally better than those near the tip or
the base .

21. As soon as you cut the budstick from the
tree or shrub, clip off the leaves; allow
about 1/2 inch of the leafstalk to remain
as a handle. Use budsticks as soon as
they are taken from the tree, but if
necessary, they may be stored in cool,
moist conditions.
Patch budding
Bud stick Rootstock

22.  Selection of scion-
 The selected scion must be defoliated while on the
mother plant at least 7 days before grafting,
keeping a part of petiole intact on
the selected shoot. Defoliation prior
to grafting method helps in swelling of a dormant
bud of the scion resulting in greater success.

24. The scion cultivar should have the flower
just opened with full-grown leaves
Bud sticks having plump, healthy buds are
suitable scions. These budsticks should be on
branches that exhibited good growth during the
current season. Leaf blades are clipped from
the budsticks, leaving the petiole intact. This
leaves a convenient "handle" for holding the
bud while it is cut from the budstick.

25. The bud and a small sliver of the wood
underneath it are cut from the budstick using
an upward slicing motion. The cut should
begin about 1/2 to 3/4 inch below the bud,
and should go deep enough into the wood so
that when the cut is finished about 1/2 to 3/4
above the bud, the bark and a small sliver of
wood are cut off. A perpendicular cut across
the top of the upward cut will separate it
from the bud stick Buds must be cut from
the bud stick just prior to grafting, otherwise
they will dry out

26. • Cutting of leaves
• Taking cut from
lower portion of
bud
• Taking cut from
upperportion and
removal of bud

28. Prepartion of scion material-
 This method of grafting is practiced in
tomato.
 For successful union, seeds of rootstock are
sown 5-7 days earlier than those scion.
 The stem of scion ( at four leaf stage ) and
the rootstock ( at four to five leaf stage ) are
cut at right angles,
 each with 2-3 leaves keeping on the stem.
 The stem scion is cut in a wedge and the
tapered end is fitted into a cleft cut in the
end of the rootstock. The
 graft is held firm with a plastic clip.

30.  The hypocotyls of the scion and rootstock
are cut in such a way that
 they tongue into each other and the graft
in secured with a plastic clip.
 This method is common in melons and
other cucurbits.(tongue approach grafting)
 In such case, seeds are sown 10-13 days
before grafting for cucurbits and 7-10 days
before grafting for pumpkin to ensure
uniformity in diameter.
