Softwood grafting in sapota
SAPOTA (Manilkara achras) is a tree native of Tropical America.
Inarching in Sapota is the commercial method of propagation
practice over forty years. This method is tedious, cumbersome and
time consuming.
One of the advancements in propagation of sapota has been the
commercial exploitation of softwood grafting.
About one year old rootstock of pala (Manilkara hexandra) growing
outdoors are selected and all side branches are removed.
The stock is then cut down to a height of 20 c.m. above soil
level. Scions should be 8 to 10 c.m. long and of pencil thickness
with buldging tips. The colour of the scion should be turning
from green to brown.
For precuring, leaf blades are clipped off seven to ten days
before grafting. When the petioles dry and drop off, the scions
can be detached from the tree and used for grafting.
Congitudinal cut of 3-4 c.m. is made and the scion wedge is
inserted to the software portion of rootstock and tied with a
polythene strip of 200 gauge thickness.
The grafts are kept in shade or mist chamber for 15 days and
later transfer the successful grafts to open place.
Treating the scion with IAA at 750 ppm. increase the percentage
of success. Higher percentage of (more than 95) success can be
obtained from this method.
