Description The study was conducted to find out most suitable method of
grafting in jack at the Horticultural Research Station, GKVK, Bangalore.
The softwood grafting and epicotyl grafting study was conducted to find
the best month for grafting and suitable growing conditions, additionally
epicotyl grafting study was carried to find the optimum age of rootstock.
These graftings were done in mist chamber, green house and open
condition. The softwood grafting carried in February was recorded the
maximum graft success and per cent of graft survival. The minimum
number of days taken for sprouting was recorded in January. The
maximum girth of rootstock, number and length of sprouts and plant
height was recorded in November. The highest length, breadth and leaves
area was recorded in March. Maximum extension of growth of sprouts
was recorded in January. Epicotyl grafting was carried for different
months under three growing conditions with rootstocks of different ages
(7, 14, 21 days). Maximum girth of rootstock and minimum number of
days taken for sprouting was recorded significantly highest on 21 days
old rootstocks grafted in June. The maximum number of sprouts, length
of sprouts, plant height, number of leaves, breadth of leaf and leaf area
was highest on 14 days old rootstocks, grafted in June. The maximum
girth of scion was recorded in May, grafted on 21 days old rootstocks.
Highest percentage of graft success, graft survival, extension of growth of
sprouts was on 7 days old rootstocks grafted in June. The highest length
of leaves was recorded on 14 days old rootstock grafted in May. The
results revealed that, the both softwood and epicotyl grafting methods
were successful, but the epicotyl grafting recorded highest percentage of
graft success (74.17%) and found to be best when compared to softwood
grafting (46.83%). Both softwood and epicotyl grafting could be adopted
for large scale multiplication of jack with uncured scion. Further with
respect to growth structures, grafted plants placed in mist chamber was
best for all the parameters followed by green house and open condition.
