Changes in metabolites was studied in healthy and malformed panicles and shoots bearing malformed panicles (SBMP) as well as shoots bearing healthy panicles (SBHP) of Dusheri mango at four developmental stages: (1) fully swollen buds (2) bud inception (3) fully grown panicles prior to full bloom, and (4) fully grown panicles at full bloom for two consecutive years. The malformed panicles and SBMP exhibited lower levels of carbohydrates than healthy panicles and SBHP. The C/N ratio was lower in malformed panicles and SBMP than in healthy ones at all developmental stages except stage 1 in shoots where the ratio was higher. The non-reducing sugars were higher in malformed panicles in stages 2 and 4 and SBMP at all stages than in healthy panicles and SBHP. The malformed panicles and SBMP exhibited significantly higher levels of starch and total phenolics than healthy panicles and SBHP at all stages. The contents of orthodihydroxy phenolics, DNA, RNA and free amino acids were lower in malformed panicles and SBMP than in healthy organs at all stages. Malformed panicles had a lower level of arginine and higher levels of valine, tryptophan, and aspartic acid than healthy ones at all stages. Amounts of cysteine and methionine were higher in SBHP than SBMP at stages 3 and 4.
