Restoration of normal growth in vegetatively malformed “Kent” mango (Mangifera indica L.) cultivar

Abstract

This study was carried out to restore normal growth in one year field grown trees of “Kent” mango cultivar suffering symptoms of vegetative malformation. Single and combined foliar treatments of BA, NAA, and GA3 were tested following a comprehensive treatment composed of pruning malformed branches 5 cm below the infected area, spraying with stroby (fungicide-acaricide), and fertilization with 100 g urea/ tree. Symptoms of malformation were not detected 6 and 12 months after the test, even in control trees, suggesting the adequacy of the comprehensive treatment for the control of vegetative malformation. However, single application of either GA3 or NAA enhanced growth significantly. Key words: Mango, Malformation, Plant Growth Regulators.
