Abstract : Morphological differences in healthy and diseased mangos (Mangifera indica) were examined. Diameters of malformed main branches, secondary inflorescence branches, stems, and leaf petioles were greater in unhealthy than in healthy plants, but their basic structure was not changed. Tissue thickness of every organ was greater in diseased than in normal plants. Although the peripheral, tannin-filled cortex was thicker in malformed than in normal plants, tannin concentrations apparently had little bearing on this condition. Other deformations included distorted shoot apices and badly-defined leaf primordia. Microbial etiology for malformation in mango could not be established.
