A study was carried out to determine the graft compatibility of bitter gourd scions (Palee F1 and CO 1) with ten different cucurbitaceous rootstocks. The grafting technique adopted in this study was side grafting. Graft compatibility was determined by assessing the survival rate of the grafted plants after regeneration of vascular bundles across the graft interface and vegetative growth of the scion. | Graft compatibility and anatomical studies of bitter gourd Momordica charantia L. scions with cucurbitaceous rootstocks
