| Tartalmi kivonat: | This main goal was to test Principal Components & Classification Analysis (PC&CA), an exploratory multivariate technique, for FRAP capacity evaluation of Romanian permanent grassland forages depending on fertilization: organic or mineral. The vegetal samples were harvested in the middle of June from hill grassland of Caras-Severin. Seven cases and fifteen variables were chosen for the multivariate data matrix. PC&CA offered the possibility to differentiate between organic fertilized cases from those fertilized exclusive mineral or unfertilized. The highest positive correlation coefficients for FRAP capacity were found for the two species from others botanical family, Inula britannica and Rosa canina. PC&CA can be considered a useful and flexible statistic instrument to evaluate the FRAP capacity of the grassland forage in the middle of June, depending on fertilization, in the soil-clime conditions of Caras-Severin. |
