dc.description.abstractThe present investigation entitled “Influence of Ramphal (Annona reticulata L.) rootstock on custard apple (Annona squamosa L.) cvs. Balanagar and Arka Sahan with an objective to study the influence of Ramphal (Annona reticulata L.) rootstock on graft success, survival per cent and vigour of custard apple cultivars. The experiment was carried out at Main Horticultural Research and Extension Center (MHREC), UHS, Bagalkot (Karnataka) in the year 2021. The experiment was laid down in a Completely Randomized Design and the observation was recorded on growth, success, survivability and biomass parameters of grafted plants of custard apple cultivars. The experiment comprised of eight treatments viz., T1- Softwood grafting of Balanagar on 15th January, T2- Softwood grafting of Balanagar on 30th January, T3- Softwood grafting of Balanagar on 15th February, T4- Softwood grafting of Balanagar on 28th February, T5- Softwood grafting of Arka Sahan on 15th January, T6- Softwood grafting of Arka Sahan on 30th January, T7- Softwood grafting of Arka Sahan on 15th February, T8- Softwood grafting of Arka Sahan on 28th February which were replicated thrice. The results of the present investigation showed significant differences among the grafts of different treatments tried for all the characters studied. In growth characteristics, treatment T7 recorded significantly the maximum number of sprouts per graft (3.40), length of the sprouted shoot (25.37 cm), number of leaves (26.54), leaf area (30.66 cm2 ), leaf area per graft (898.39 cm2 ), scion girth (7.97 mm), rootstock girth (6.92 mm), girth of graft union (8.22 mm), length of the longest root (34.73 cm) with the highest survivability of graft (91.10 %) at 90 days after grafting and graft success (95.55 %) at 30 DAG. Although, the minimum number of days required for grafting (8.31) was recorded in T3. With respect to biomass characteristics, T7 recorded the maximum fresh weight of shoot (33.43 g), dry weight of shoot (18.36 g), dry weight of root (12.40 g) and shoot: root ratios (1.47 and 1.48) of fresh and dry weight basis, respectively. However, treatment T7 is statistically on par with T6 for most of the parameters studied. Hence, it can be concluded that T7 (softwood grafting of Arka Sahan on 15th February) performed best in terms of graft growth, success, survivability and biomass.
