There is a commercial and beneficial interest of producing yerba mate leaves into different grades of caffeine. This work uses a handheld and bench near-infrared (NIR) spectroscopy to compare and predict, using partial least squares (PLS) regression, the amount of caffeine in yerba mate leaves. Standards of pure caffeine were compared, using high-performance liquid chromatography (HPLC), with extracts of yerba mate. The bench spectroscopy gave a strong confidence model of caffeine prediction, whereas the handheld related to a fair model. For first detection and initial separation of yerba mate in the field, the modeling proposed can be used to predict caffeine intensity. |

group of related bacilliform, nuclear viruses with a bisegmented negative-sense RNA genome that are transmitted by Brevipalpus mites likely in a circulative?propagative manner were recently classified in the new genus Dichorhavirus, family Rhabdoviridae. These viruses cause localized lesions on leaves, stems, and fruits of economically significant horticultural and ornamental plant species. Among its members, orchid fleck virus, citrus leprosis virus N, and coffee ringspot virus are most prominent. This chapter summarizes the current knowledge about these viruses, available detection techniques, and their interactions with their plant hosts and mite vectors. |
