Abstract
Pomegranate (Punica granatum L.) is one of the important commercial fruit crops grown mainly on marginal and sub-marginal lands in the states of Maharashtra, Karnataka and Andhra Pradesh.
The air layering method is commonly used for multiplication of planting materials.
Grafting has not been tried in India for propagation of elite saplings.
Presently, wilt is an emerging threat to the pomegranate industry under South Indian conditions and without availability of a standard grafting technique and tolerant rootstock, it is difficult to solve the wilt problem.
In view of this, an attempt was made to standardize the grafting method and time so that grafting can be done on suitable rootstock that can help overcome the wilt problem.
Two grafting methods (wedge and tongue grafting) and five dates (15 December, 30 December, 15 January, 30 January and 15 February) were evaluated during 2007-08 at the National Research Centre on Pomegranate, Solapur, Maharashtra, India.
One-year-old seedlings of Phule Arakta were used as a rootstock for the present study.
In general, scion sprouting started between 8 and 12 days after grafting.
Significantly higher scion sprouting was recorded with wedge grafting done in the last week of January after 15 (90.00%) and 21 (96.67%) days of grafting.
Consequently maximum graft success (85.00%) was recorded after 90 days of grafting with wedge grafting done on 30 January.
Plant height and scion length after 6 months of grafting was higher when wedge grafting was done between 30 December and 30 January.
Grafted plants during this period had perfect union as indicated by normal diameter recorded at graft union.
This reflected high scion and rootstock compatibility.
However, performance of wedge grafted plants is to be evaluated under field condition.
