Popis:	The sonic vibration characteristics of 5 major apple (Malus domestica Borkh.) cultivars were evaluated. The resonant frequency (f) and the mass (m) of individual intact apples were measured over 4 weekly harvests and again after 2½ and 5 months in storage. A nondestructive index of firmness, f2m, for each apple was calculated and compared with other measures of fruit texture. The f2m index was directly correlated with Magness-Taylor pressure test measurements of firmness and with sensory ratings of crispness, juiciness, and firmness, especially crispness. It was inversely related to mealiness. Correlations were affected by differences among cultivars; results were best and most consistent for ‘Golden Delicious’ and ‘Rome Beauty’.
