"Pears of 22 varieties were analysed, most of them tested in loading-unloading compression tests between two flat rigid plates to determine variety sensitivity to bruising. The analysis of the obtained results shows that from a mechanical point of view, the susceptibility of the fruit to bruising increases with both the decreasing degree of fruit elasticity and hysteresis losses. Because both the parameters are negatively correlated a new suitable mechanical parameter was defined as a measure of the variety resistance to bruising: Bruising harmonic index (BHI 0,5) the harmonic mean value of characteristic hysteresis losses and degree of elasticity at formation of bruise spots of 0.5 cm3 in volume." .
