甜瓜表面的木栓化网纹组织是生长过程中膨胀的果肉与固化的表皮之间机械失衡导致果皮破裂的残留。这种网纹的出现是评估甜瓜品质的一个重要指标；然而，对网纹的几何形状进行的定量研究却很少。本研究利用图像分析对网纹所包围的细小表皮碎片面积进行了统计分析，并探索了支配碎片面积概率分布的一个通用规律。我们发现，碎片面积分布遵循由修正贝塞尔函数所确定的一个普遍规律，这与脆性材料断裂行为的理论观点是一致的。
The suberized netting tissue on the surface of muskmelons is a remnant of the rind fragmentation caused by the mechanical imbalance between the expanding flesh meat and the solidified epidermis during growth. The appearance of this netting pattern is an important indicator for assessing the quality of muskmelons; however, very few quantitative studies have been conducted on the geometry of the netting. This study statistically analyzed the areas of fine epidermis fragments surrounded by the net using image analysis and explored a common rule governing the probability distribution of the fragment area. We found that the fragment area distribution follows a universal law by the modified Bessel function, which is consistent with the theoretical argument for the fracture behavior of brittle materials.
