Influence of Perennial Rootstocks and PKM1 Scion on Nutritional Content of Grafted Moringa (Moringa oleifera Lam.)

The investigation was undertaken at Horticultural College ad Research Institute, Coimbatore to identify the graft compatibility of seven perennial moringa rootstocks for PKM 1 Moringa scion under drought condition. Among the seven rootstocks, moolanur moringa is identified as the best rootstock for PKM 1 Scion with wedge method of grafting as confirmed with histological method. The leaf nutritional contents were analysed in all the seven perennial rootstocks, PKM1 moringa scion and graft combinations. Among the rootstocks, Padasolai local rootstocks had highest calcium content (559.93 mg/100g). Moolanur moringa rootstocks had highest potassium content (358.46 mg/100g) and iron content (2.54 mg/100g). Among the graft combinations highest potassium content (368.74 mg/100g) and highest iron content (2.76 mg/100g), highest C/N ratio of 24.82 and highest total nitrogen content of 1.48% were recorded in the PKM-1 moringa scion grafted on to moolanur moringa rootstock.
