Abstract : Stionic relationship is an important factor for successful graft production. Stone grafting was performed by
cleft method in the month of July-August on seedling rootstocks (Mango seedlings) of on four age groups i.e. 5 days,
10 days, 15 days and 20 days using Amrapali as scion stock at Kanpur district of Uttar Pradesh. The objective was
to analyze age effect of mango seedling rootstock after stone grafting of cultivar Amarpali. Statistically data was
analyzed with randomized block design replicating single interval five times. The height (24.4 cm) and sprouting
percentage (83%) of scion, girth of rootstock and scion (6.3 mm) was significantly higher on grafts made on 10 days
old rootstocks and minimum-sprouting percentage was recorded with 20 days old rootstocks. In vegetative
parameters length (17.12 cm) and width (4.80 cm) of leaf was recorded maximum on 10 days old and minimum on
5 days old rootstock. The higher survival percentage was exhibited by 5 days and 10 days old rootstock, which
shows suitability for this technique. It was revealed that stone/epicotyl grafting performed better in terms of growth
and survival when rootstocks up to 10 days old were used for grafting.
