Prediction of macro- and microelements content in Croatian common bean landraces (Phaseolus vulgaris L.) by NIR spectroscopy
In this study, near-infrared spectroscopy (NIRS) was used to predict the contents of essential macro- and microelements in common bean (Phaseolus vulgaris L.) accessions of most widespread Croatian landraces. Total of 175 samples were used for the model development by modified partial least square (...

| 520 | |a In this study, near-infrared spectroscopy (NIRS) was used to predict the contents of essential macro- and microelements in common bean (Phaseolus vulgaris L.) accessions of most widespread Croatian landraces. Total of 175 samples were used for the model development by modified partial least square (MPLS), principal component regression (PCR) and partial least square (PLS) techniques. Based on the coefficients of determination (R2), standard error of calibration (SEC) and error of prediction (SEP) the models developed were (i) nearly applicable for nitrogen (N) (0.89, 0.12 and 0.45 respectively), (ii) poor for iron (Fe), cinc (Zn), potassium oxide (K2O) and potassium (K), (iii) usable for phosphorus pentoxide (P2O5), phosphorus (P), phytic acid (PA) and manganese (Mn). The MPLS regression statistics suggested the most accurate models developed comparing with PLS and PCR. It was concluded that a wider set of common bean samples needs to be used for macro- and microelements prediction by NIRS. | ||
| 520 | |a U ovome je istraživanju korištena spektroskopija u bliskome infracrvenom području (NIRS) za procjenu količine esencijalnih makro- i mikroelemenata u uzorcima najčešće uzgajanih kultivara graha (Phaseolus vulgaris L.) u Republici Hrvatskoj. Ukupno 175 uzoraka graha korišteno je za razvoj kalibracije uporabom modificirane metode najmanjih kvadrata (MPLS), metode regresije osnovne komponente (PCR) i metode najmanjih kvadrata (PLS). S obzirom na koeficijent korelacije (R2), standardnu grešku kalibracije (SEC) i standardnu grešku procjene (SEP), razvijeni kalibracijski modeli su (i) gotovo primjenjivi za procjenu dušika (N) (0,89; 0,12 i 0,45), (ii) slabo primjenjivi za procjenu željeza (Fe), cinka (Zn), kalijevog oksida (K2O) i kalija (K) te (iii) upotrebljivi za fosfor pentoksid (P2O5), fosfor (P), fitinsku kiselinu (PA) i mangan (Mn). Najpouzdaniji kalibracijski modeli razvijeni su korištenjem regresijskoga modela MPLS u usporedbi s kalibracijskim modelima dobivenim korištenjem PLS-a i modelima PCR-a. Zaključeno je da je za procjenu makro- i mikroelemenata spektroskopijom u bliskome infracrvenom području (NIRS) potrebno prikupiti veći broj uzoraka graha širih varijacija istraživanih makro- i mikroelemenata. | ||
