From: Apple metabolism under oxidative stress affects plant cell wall structure and mechanical properties

Nano-scale properties of apples subjected to oxidative stress of various durations: (a) Young modulus of dried cell wall material (N = 750, ten cell wall fragments per each cultivar-treatment variant, 25 individual sampling points per fragment), (b) average area of pectin molecules (N = 13,000), (c) average solidity of pectin molecules (N = 13,000). Data points show average values for all cultivars tested, while distributions of numeric data for treatments are depicted using density curves. Data points with different letter indices are significantly different (One-way ANOVA, Tukey HSD, p < 0.05).
