“…Current analysis on irrigation technologies to improve food availability generally focus on production yields but does not bring information or understanding about molecular changes occurring in plants. [9][10][11][12][13] Metabolite concentrations and diversities present in vegetal material provide integrated information about cellular function at the molecular level with which it is possible to determine cell or tissue phenotype responses to environmental and even genetic alterations besides predicting organism behavior for possible improvements. [14][15][16] The group of metabolites (i.e., metabolome) of a cell or vegetal tissue has a rapid response to any environmental alteration, although, owing to the enormous diversity existing in organisms, changes at the molecular level have been considered to be quite unique for each kind of plant increasing the difficulty of generalizing biomarkers as a function of specific stresses.…”

The effects of water-deficit stress on irrigated and unirrigated field plants of Coffea arabica L. genotype IAPAR 59 were investigated. Plant extracts were obtained following an ethanoldichloromethane-hexane statistical mixture design. Proton nuclear magnetic resonance (1 H NMR) fingerprints of the extracts were discriminated using factor analysis (FA) and hierarchical clustering techniques. Extracts from the 1:1:1 ternary mixture presented the largest discriminations compared with those from the pure solvents or their 1:1 binary mixtures. Metabolites resulting from fermentation processes and nutritional deficiencies as well as senescence and abscission precursors such as lactate, arginine and methionine were prevalent in unirrigated plants that can provoke expressive decreases in bean productivity as well as premature plant aging. Amino acids that control regulatory, physiological processes and soil salinization have higher concentrations in the irrigated plants. The NMR assignments of eighteen substances observed here were confirmed by electrospray ionization mass spectrometry.

“…Na cultura do café a instalação dos sistemas de irrigação pode ser feita antes ou durante a fase de formação da lavoura, iniciando nos dois primeiros anos da cultura implantada no campo com plantas jovens; na fase de produção entre o terceiro e quinto ano após sua implantação durante o seu crescimento e desenvolvimento; ou depois da lavoura alcançar sua fase já adulta, a partir do sexto ano. Várias pesquisas (CUSTÓDIO et al, 2014(CUSTÓDIO et al, & 2013FERNANDES et al, 2012) objetivaram determinar a demanda hídrica dos cafeeiros e em diferentes situações relacionando seus componentes produtivos e qualitativos.…”

Coffee is one of the most important non alcoholic beverages harvested in the field, exported under different ways and considered one of the most important commodities in the global market. The objective of this study was to investigate the effect of different irrigation management on some qualitative features of fruits and grains of coffee plants in two sides of exposure to solar radiation (SPESR) and three positions in the plant in the first harvest after pruning. The experiment was conducted using randomized blocks in a split-plot design with four replicates. It was developed in Matão (SP), Brazil, in the 2010/2011 harvest season. The primary treatments were six different types of irrigation management: NI = no irrigation; CI = continuous irrigation all over the year; CI 14 A-19 M = CI, except from . Secondary treatments were the SPESR: southeast and northwest. Ternary treatments were the position in the plant: upper third, mid third and lower third. The stages of fruit ripening and coffee rating by bean size, defects and tasting quality were evaluated. The irrigated and non irrigated coffee promoted the same increase in fruit ripening, however, the advance in maturation is observed from the upper to the lower third. Non irrigated and irrigated coffee plants promoted the same increase in total defects. Greater grains are obtained with sieve 16 in irrigated coffee plants and above the value in SPESR northwest over the mocha grain.In southeast SPESR, a higher increase in cherry fruit is observed, providing better quality of the beverage over total defects.

RESUMOObjetivou-se com este trabalho verificar a maturação e a classificação do café grão cru em lavoura irrigada por gotejamento sob diferentes manejos em três safras após a poda. Cafeeiros da cultivar Acaiá MG-1474 foram irrigados desde o plantio em 1997 e recepados em 2004. O delineamento experimental utilizado foi de blocos casualizados, com cinco tratamentos e quatro repetições. Os tratamentos foram diferentes estratégias no manejo da irrigação: A= não irrigado (testemunha); B= irrigação o ano todo sempre que o teor da água disponível no solo (AD) atingiu 25% da disponibilidade total de água (DTA) na camada de 0-40 cm; C= irrigação o ano todo sempre que AD<75% DTA na camada de 0-40 cm; D= irrigação o ano todo, quando, em janeiro, fevereiro, março, julho, outubro, novembro e dezembro AD<75% DTA e em abril, maio, junho, agosto e setembro, quando AD<25% DTA na camada de 0-40 cm; E= irrigação em abril, maio, junho, agosto e setembro, quando AD<75% DTA na camada de 0-40 cm. O manejo de irrigação E é o mais indicado por consumir menor quantidade de água e permanecer no grupo com maior percentual de grãos com peneiras 16 acima em detrimento no total de defeitos intrínsecos. As maiores ocorrências de defeitos foram nas classes de grãos verde, ardido e mal granado. Palavras-chave: Coffea arabica ABSTRACTThe objective of this study was to evaluate maturation and classification of coffee beans under drip irrigation using different management in three harvests after pruning.
