Efeitos de estresse hidrico na composição bioquimica de grãos de Coffea arabica cv. Rubi : [Preprint]

Amounts of some biochemical compounds of coffee fruits (caffeine, total lipids, sucrose, chlorogenic acids and trigonellin) were evaluated by the near-infra red spectroscopy (NIRS) in the beans produced from adult plants to Coffea arabica cv. Rubi, cultivated in field condition, under different hydric regimes. Results of these analyses showed that the lack of irrigation during the period of coffee bean development influenced the biochemical composition of these beans. When compared with beans from plants with continuous irrigation, those of plants grown without irrigation presented lower amount of caffeine and chlorogenic acids (CGA) but higher contents of sucrose and total lipids. The results presented here showed that water stress influenced coffee bean metabolism, particularly the contents of biochemical compounds known to affect the coffee cup quality.
