Abstract: Near-infrared reflectance (NIR) spectroscopy combined with chemometrics was used to assess nitrogen (N) and dry matter content (DM) and chlorophyll in whole-wheat plant (Triticum aestivum L). Whole-wheat plant samples (n = 245) were analysed by reference method and by visible and NIR spectroscopy, in fresh (n = 182) and dry (n = 63) presentations, respectively. Calibration equations were developed using partial least squares (PLS) and validated using full cross-validation (leave-one-out method). Coefficient of determination in calibration (R2CAL) and the standard error of cross-validation (SECV) for N content in fresh sample presentation, after second derivative, were 0.89 (SECV: 0.64%), 0.86 (SECV: 0.66%) and 0.82 (SECV: 0.74%) using the visible + NIR, NIR and
visible wavelength regions, respectively. Dry sample presentation gave better R2 CAL and SECV for N compared with fresh presentation (R2 CAL > 0.90, SECV <0.20%) using visible + NIR. The results demonstrated that NIR is a suitable method to assess N concentration in wheat plant using fresh samples (unground and undried). |

Abstract.
A biotype of clary sage (Salvia sclarea L.) growing in Uruguay was evaluated for its suitability to be cultivated in Uruguay. Essential oils from the inflorescences and leaves of plant harvested at full flowering and early seed ripeness stages were obtained by steam distillation and characterized by GC and GC-MS (quadrupole). Twenty-seven components (91-98% of the total composition) were identified. The oil was characterized by a high content of linalool (8-22%), linalyl acetate (39-48%) and sesquiterpenes, with germacrene D (8-20%) and (E)-β-caryophyllene (3-5%) as the main components. The enantiomeric distribution of α-pinene, sabinene, β-pinene, limonene, linalool, linalyl acetate and germacrene D was studied by multidimensional HRGC-HRGC. The development stage did not influence the oil composition or the enantiomeric distribution of the studied components of the clary sage biotype over the period of evaluation. It is concluded that clary sage can be grown as an economically viable crop in the south of Uruguay.
