Abstract

Grafting experiment between three commercial varieties of eggplant susceptible to bacterial wilt and four different resistant rootstocks was done in the green house of the Vegetable Crops Section, Division of Horticulture, Department of Agronomy, the main objective is to determine their graft affinities and grafting effects on the characteristics of these solanaceous vegetables.

The three susceptible scions showed a high degree of graft affinity when grafted onto four resistant stocks of tomato (UPCA Selection #1169, Hawaii #2) and Eggplant (UPCA #64-43-36). Pepper as a stock showed poor affinity to all susceptible scions. However, eggplant showed good compatibility to all susceptible scions. This result was expressed in all horticultural characteristics exhibited by the three susceptible scions. In all cases the growth, number of leaves and flowering were comparable to the plants grown in the root system. The three scions grown on three rootstock (UPCA Selection #1169, Hawai #2) and Eggplant (#64-43-36) showed no significant difference. On the other hand pepper as stocks possessed a lesser number of leaves, poor graft affinity, retarded growth of scions, and a lesser number of flower cluster.

This experiment suggests that grafting three susceptible scions onto four resistant stocks is possible.
