Abstract
The present investigation entitled “Standardization of grafting techniques in
pomegranate (Punica granatum L.) was carried out at Main Horticultural Research and
Extension Centre (MHREC) UHS, Bagalkot (Karnataka) during June 2018 -
February 2019.
Pomegranate is mainly propagated by air layering. Recently, wilt has emerged as
a major threat to the pomegranate industry in Maharashtra, Karnataka and Andhra
Pradesh. Presently, neither any standard grafting techniques nor suitable rootstock is
available by which the wilt problem could be controlled. Grafting method and grafting
time have significant effect on the growth parameters of pomegranate. Grafting
techniques treatment viz Twelve grafting techniques treatment T1: softwood grafting on
15th June, T2: softwood grafting on June 30, T3: softwood grafting on 15th July,
T4: softwood grafting on 30th July, T5: softwood grafting on 15th August, T6: softwood
grafting on30th August, T7: tongue grafting on 15th June, T8: tongue grafting on 30th
June, T9: tongue grafting on 15th July, T10: tongue grafting on 30th July, T11: tongue
grafting on 15th August, T12: tongue grafting on 30th August. The result of the
experiment, T3 (softwood grafting on 15th July) proved to be the most effective in
increasing sprouting percentage ( 58.33 %) at 150 DAG , grafting success (75 %) at 60
DAG, scion length (57.00 cm) at 150 DAG and plant height ( 71.71 cm) at 150 DAG .
With respect to scion diameter T4 recorded the maximum scion diameter (6.83 cm)
at 150 DAG. Number of leaves per graft was recorded maximum in T6 (125.25)
at 150 DAG.
From the present investigation, it has been found that within short time more
number of grafts can be obtained.
