Studies on the effect of age of rootstock and scion on success, survival and growth of brinjal grafts

Abstract

The experiment entitled “Studies on effect of age of rootstock and scion on success, survival and growth of brinjal grafts” was carried out in 2018-19 to standardize the age of scion and rootstock seedlings for grafting which consists of nine treatment combinations viz.T1: 20 days old scion grafted on 20 days old rootstock, T2: 25 days old scion grafted on 20 days old rootstock, T3: 30 days old scion grafted on 20 days old rootstock, T4: 20 days old scion grafted on 25 days old rootstock, T5: 25 days old scion grafted on 25 days old rootstock, T6: 30 days old scion grafted on 25 days old rootstock, T7: 20 days old scion grafted on 30 days old rootstock, T8: 25 days old scion grafted on 30 days old rootstock, T9: 30 days old scion grafted on 30 days old rootstock and each treatment was replicated thrice in Randomized Block Design.The brinjal cultivar Swarn Pratibha was used as rootstock and Kali-rawai was used as scion. Less number of days (7.60) were required for graft union in T1 whereas highest number of days (8.20) were required for graft union in T6. Highest grafting survival (75.33%) at 30 DAG was observed in treatment T5 whereas lowest grafting survival (70.67%) at 30 DAG was observed in treatment T3 and T7.
