Abstract : An experiment was carried out at the Horticultural Research Station, Bangalore during 1985-86 using 6-month-old mango cv. Nekkare plants raised in containers or in situ as the rootstocks. Shoots of the scion cultivars, Alphonso, Dashehari, Langra, Mallika, Pairi and Totapuri were preconditioned for 10 days before grafting. The phenol content of the scion cultivars was estimated after preconditioning for 0, 3, 6, 9 and 12 days. The highest percentage grafting success (90%) was obtained with Dashehari and Totapuri scions with both container- and in situ-grown rootstocks. The phenol content in all scion cultivars decreased with increasing duration of preconditioning. The highest phenol content at all preconditioning stages occurred in cv. Alphonso which had the lowest grafting success with both container-grown (55%) and in situ-grown (35%) rootstocks. The lowest phenol content occurred in Dashehari. It is suggested that graft union success is related to phenol content in the scion.
