Transcript Copy of RLO Grafting techniques in Mango

Introduction
• Mango is propagated by various methods by nurserymen
depending on success and preference of the growers in the
region.
• Inarching grafting method is commonly practiced in western India.
In-situ softwood grafting method is popular and effective in arid
and semi-arid region.
• Stone grafting is most successful, easy, economical and quick
method for mango propagation.
Veneer Grafting
Selection of Scion: Scion stick or bud stick should be healthy
with swollen eye buds and 10 to 15 cm length and of pencil size
thickness. Leaves are defoliated 8 to 10 days before cutting for
grafting.
Procedure
•
Make a slanting cut up to 5 cm to the bud stick and same length
deep notch to mango rootstock seedling.
•
Put the cut part of scion in the notch of rootstock and tie with 1
cm wide polythene film tape.
Veneer Grafting
Season: Veneer grafting should be performed in the month of September to
October
After Care
•
Grafted plants / seedlings are kept humid and moist condition.
•
Scion shoot starts sprouting in about 3 to 4 weeks.
•
Polythene strip should be removed after the success of graft.
•
Grafts ready for planting in 3 months. Success rate is 75 to 80 %.
Stone Grafting
Selection of Scion: Scion sticks with 7 to 8 cm long from
current year growth from healthy mother plants should be
selected.
Procedure
•
•
•
Stone grafting operation should be performed in July- August
months.
Vertical cut of 3 to 4 cm is given on the rootstock and a
corresponding wedge shaped cut is given on the scion.
Wedge shaped cut on scion is matched with the cut on rootstock
and then tied firmly with a polythene strip.
Stone Grafting
After Care
•
Remove the growing shoots from root stock and inflorescence from
grafted scion immediately after emergence.
•
Remove the polythene strip when union is formed and protect the graft
from hot sun, pest and disease attack.
Advantages
•
Survival Success is more than 80 to 90 %, Requires less time and this
Method is very suitable for coastal region.
Inarch Grafting
Selection of Scion and Rootstock:
•
Select one year old at least two feet long and healthy rootstock
grown in pots / polythene bags.
•
Root stock plant and scion stock plant sticks should have equal
thickness. It should be from current year growth and from
healthy mother plant
Season
•
August-September is best season for Inarch Grafting.
Inarch Grafting
Procedure:
•
Arrange the root stocks and scion tree on some platform or
mandapam and Mark the grafting locations on stock and scion.
•
Remove 5 cm long, 1 to 2 cm wide & about 0.2 cm deep slice of
bark along with wooden part from stock and scion branches.
•
Bring the cut surfaces together, cover the joint with a banana leaf
sheath and tie them together with soft threads and cover joint part
with cow dung plaster to protect from rain water.
Inarch Grafting
After care
•
Water the plants as and when required. Cut the scion from the
parent tree after 2 to 3 months when the wound has healed.
•
One week after separating the plant from root stock, the part of the
rootstock above the graft is cut off.
•
Keep the graft in semi shading area to harden the graft before
transplanting into the main field.
