Abstract : In order to explore the pathogenesis of mango malformation, ELISA was used for measuring the endogenous hormones, including IAA, ZR, GA3 and ABA, and paraffin section was conducted for comparing anatomical structure between malformed stems and the health. The results showed that the hormones in malformed stems were 3.03, 1.77, 5.14 and 1.74 times higher than the health respectively. The anatomical structure characteristic was different. In malformed stems, parenchyma cells in cortex and phloem fiber were more, but vessel and diameter were less. The branch and leaf trace also existed in internodes. The cells in marrow were a quarter of the control.
