Ultraviolet characteristic profiles and infrared spectroscopic (FTIR) fingerprints of green bean extracts of Coffea arabica L., cv. IAPAR 59, cultivated in two planting patterns, rectangular and square, and at two different ...
Integrated chemometric approach to optimize sample preparation for detecting metabolic changes provoked by abiotic stress in Coffea arabica L. leaf fingerprints

Marcheafave, Gustavo G.; Tormena, Cláudia D.; Afoso, Sabrina; Rakocevic, Miroslava; Bruns, Roy E.; Scarminio, Ieda S. (Sociedade Brasileira de Química, 2019)

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 ...
