Biotic stress factors such as Rhizopus oligosporus and Aspergillus niger mycelial extracts and abiotic elements methyl jasmonate (MJ) and salicylic acid (SA), when administered through floral spray to Coffea canephora, showed significant influence on major bioactive metabolites of beans. Up to 42% caffeine, 39% theobromine and 46% trigonelline, along with 32% cafestol and kahweol content elevation was evident under respective elicitor treatments. Over all, the surge in respective metabolites depends on elicitor stress type and concentration. Abiotic factors MJ and SA were found to be efficient at 1 to 5 ?M concentration in augmenting all the metabolites, compared to R. oligosporus and A. niger spray at 0.5 -2.0 % wherein the response was moderate as compared to abiotic stress, however significant compared to control. Though this elevation in caffeine, theobromine, cafestol and kahweol is not warranted from quality point of view, increase in trigonelline improves coffee quality. Besides increase in metabolites, stress mediated augmentation of bioactive compounds in coffee has a wide scope for studying gene expression pattern.. ??
