grafting in mango

Mango is propagated by both sexual and vegetative propagation. Various
methods of propagation include softwood, veneer grafting, side grafting,
and epicotyl grafting, which are most commonly found in India. Factors such
as environmental factors, varieties, growing seasons, shoot age, rootstock
age, scion wrapping technique, shoot maturity and rootstock, etc. all of
these have an impact on the success and survivability of mango grafting.
When compared to a season of the year, rainy season transplant in mango
shows good growth and survival percentage results.
Most common grafting are inarching, side grafting, wedge grafting, and
veneer grafting, but the cheap, easy and fast grafting was stone grafting,
which they produce in a shorter time and area in good quantity and quality.
This method is widely used in the states of Karnataka, Maharashtra, and
Kerala.
Veneer Grafting
For conducting this grafting operation, a downward and inward 30-40 mm
long cut is made in the smooth area of the stock at a height of about 20 cm.
At the base of cut, a small shorter cut is given to intersect the first so as to
remove the piece of wood and bark
.Veneer grafting is a useful technique that can be used on many different
plant species. It’s especially useful when there’s a difference in size between
the scion and the rootstock
A strong, dense hardwood that repels water damage, Mango has a beautiful
tropical look and feel. And a sweet smell. Making it a popular, sustainable
choice for wood veneer, architectural plywood, indoor and outdoor furniture,
flooring, ukuleles, and turned objects.
How it’s done: To perform veneer grafting
on a mango tree, you can:
Make a downward and inward cut that’s 30–40 mm long in the
smooth area of the stock. The cut should be about 20 cm high.
Make a shorter cut at the base of the first cut to remove the piece of wood and bark.
Chamfer the surfaces of the scion and stock so they face each other
Tie polythene or alkethene strips around the union.
When to do it: September is generally considered the best month for grafting mango
trees
What to use: Some recommend using 100-day-old precured scions for grafting.
What to expect: Grafts from precured scions tend to be more successful than those
from non-precured scions. Grafts from 100-day-old scions also tend to be more
vigorous than those from 120-day-old scions
Veneer grafting is a simple and effective method of
mango propagation that has several advantages
including:
Mass scale propagation
Veneer grafting is a promising method for commercial mango propagation on a large
scale.
Shorter time to flower and produce fruit
Grafted mango trees start flowering and producing fruit faster than other trees.
More trees per unit of land
Trees grafted on a dwarfing rootstock grow less vigorously, allowing more trees to be
accommodated on the same amount of land.
Some disadvantage of grafting in
general includes
Cost:
Grafting can be expensive
Incompatibility:
Graft incompatibility can cause physiological disorders.
Yield:
can reduce yield.
Fruit quality:
Grafting can reduce fruit quality.
Flower formation:
Grafting can reduce flower formation.
Inarching :
Inarching is a method of grafting that can be cumbersome and time-consuming. It can
also be uneconomical because only one plant is obtained from a long scion shoot.
Grafting time
The time of grafting can affect the success of the grafting. For example,
grafting in July may result in bud sprouting in 14.33 days, while grafting in
September may result in bud sprouting in 27.33 days.
Variety
The variety of mango can affect the success of the
grafting. For example, Sindhu may have a success rate of 80.12%, while
Gopalbhog may have a success rate of
55.25%.
