Effect of age of rootstock and growing medium on the success of epicotyl grafting in mango

Propagation studies in mango with epicotyl grafting were carried out with seven growth media. Six sub-treatments included grafting on 5, 7, 9, 11, 13 and 15-day-old rootstocks. The highest sprouting of graft scion was recorded in soil + FYM + sand followed by soil + leaf mold. Sprouting was significantly higher with the use of 7-day old rootstock for grafting followed by 9 and 5-day-old rootstock. The highest survival was observed with 7-day-old stock, the survival rate decreased when the age of the stock increased to 15-day. The graft survival was better in soil + FYM + sand followed by soil + FYM after 4 months of grafting. The survival percentage was higher in transplanted grafts than those grafted In-situ in polybags. Vegetative growth viz. sprout length and sprout diameter were the highest in plants grafted on 7-day-old rootstock followed by 9 and 11-day-old rootstocks.
