METABOLIC CHANGES ASSOCIATED WITH VEGETATIVE MALFORMATION OF MANGO (MANGIFERA-INDICA L)

Malformed seedlings showed significantly (P = 0.05) higher content of total carbohydrates, total sugars, reducing sugars, non-reducing sugar s, starch, total phenolics, orthodihydroxy phenolics, DNA, RNA, protei ns, total free amino acids, total amino acids, and ammonia compared wi th healthy seedlings, during three years of study, whereas the C/N rat io was significantly lower in malformed seedlings than healthy ones. T he levels of threonine, serine, proline, glycine, alanine, valine, iso leucine, leucine, lysine, histidine, arginine, aspartic acid, glutamic acid, tyrosine, phenylalanine, and tryptophan were also significantly higher compared with healthy seedlings during three years of investig ations. The contents of cysteine and methionine were higher in malform ed seedlings than healthy seedlings where these were in traces, during the three years of study.
