Abstract : Commercially mango is propagated by grafting. For uniformity in growth, yield and quality monoembryonic rootstock should be propagated by vegetative means. Ammonium N treatment for stock plant was beneficial for rooting of cuttings. Rooting was positively correlated with glucose, fructose and starch in leaves and stems of cuttings. For epicotyl grafting 8 to 16 days old stocks were best. For early growth and development of rootstock Gigaspora margarita micorrhizal fungus was advantageous. Preconditioning (defoliation) of scion for 4 to 15 days was helpful for more success of grafting. In in situ grafting maximum success was found on young rootstock at bronze leaf colour stage, rootstock 13-1 was found most salt tolerant. Talabnak and Villaicolumban were suitable dwarfing rootstocks. Mango plants having hypertrophied lenticels were resistant to flooding. Isozyme systems successfully used for examination of nucellar seedling stocks. Malformation was not transmitted through grafting. Dwarfing rootstock influenced mineral composition of scion i.e. lowest content of N, K and Ca and the highest Mg content. In grafts, dry matter distribution was found from new growth to roots at lower temperature and to the leaves at higher temperature. Scion stems had twice gibberellin content of stock stems. Rootstock and Interstocks influenced scion growth, yield and fruit quality.
