Figure 1

Spearman correlations of firmness data between destructive and non-destructive devices for Quilhuica (A,B) and Bartolillo (C,D) orchards. The firmness of the fruit stored in RA decreased rapidly once removed from cold storage conditions (day 30). The firmness of the fruit was not easily lost under CA storage and remained unaltered during the prolonged storage stage, and the fruit lost firmness faster after removal from storage at day 55. Figure 2A, 2C show the firmness loss measured by a texture analyser while Figure 2B, 2D show the firmness by a destructive device for Quilhuica and Bartolillo orchards, respectively. Differently from non-destructive devices, little change in firmness was observed when the penetrometer was used (Figure 2B, 2D).
