The study determined the influence of defoliation on the survival and growth of rooted ‘Magallanes’ Pummelo marcots at the Don Mariano Marcos Memorial State University-North La Union Campus, La Union, Philippines. Employing the Randomized Complete Block Design (CRBD) with three blocks, 10 sample plants or marcottage were used per treatment. Three treatments were used including complete removal of all leaves (T1), removal of half the number of leaves (T2), and no removal of leaves (T3). Three ‘Magallanes’ Pummelo trees at fruit bearing stage were used as parent stocks. Results indicated that removal of half the number of leaves and no removal of leaves comparably gained 100% survival of rooted pummelo marcots as compared to complete removal of leaves which recorded lower survival rate. All other parameters were found having insignificant differences.
