| Abstract:
Force-Displacement and Force-Time curves loaded from penetrometric and compression tests, receptively, were analyzed for their ability to discriminate the apple texture. The parameters extracted from the curves of each measurement, were processed in a single factorial discriminant analysis (FDA) in order to identified five apple progenitors. The correct identification of each apple progenitor, using both penetrometric and compression data curve, were realized with a discrimination accuracy of 100% for X4956, X6908, X2033, 6064 and 95% for X2888. This study showed that the identification close to 100% was due to the complementary information given by these two kinds of measurements. | |
