How a homogeneous collective of cells consistently and precisely establishes long-range tissue patterns remains a question of active research. This work explores the hypothesis of plant organs as resonators for electromagnetic radiation. Long-range structural patterns in the developing ovaries and male flower buds of cucurbit plants (zucchini, acorn, and butternut squash), in addition to mature cucurbit fruits (acorn, butternut, and zucchini squash; watermelon, and cucumber), were investigated. A finite element analysis (FEA) model was used to determine resonant EM modes for models with similar geometric and electrical parameters to those of developing organs. Main features of the developing ovaries (i.e. shape of placental lines, ovum location, definition of distinct tissue regions), male flower buds (i.e. early pollen tube features), and mature fruits (i.e. septa placement, seed location, endocarp and mesocarp) showed distinct correlations with electric and magnetic field components of electromagnetic resonant modes. On account of shared pattern signatures in developing organs and the EM resonant modes supported by a modelled structure with similar geometric and electrical properties to those of cucurbit organs, experimental investigations are warranted. The concept of a developing organ as an EM dielectric resonator may extend to a variety of morphogenetic phenomena in a number of living systems.
细胞的同质集合如何持续且精确地建立远距离组织模式仍是一个活跃的研究问题。这项工作探索了植物器官作为电磁辐射谐振器的假说。对葫芦科植物（西葫芦、橡子南瓜和胡桃南瓜）发育中的子房和雄花芽，以及成熟的葫芦科果实（橡子南瓜、胡桃南瓜和西葫芦；西瓜和黄瓜）中的远距离结构模式进行了研究。使用有限元分析（FEA）模型来确定与发育器官具有相似几何和电学参数的模型的共振电磁模式。发育中的子房（即胎座线的形状、卵子位置、不同组织区域的定义）、雄花芽（即早期花粉管特征）和成熟果实（即隔膜位置、种子位置、内果皮和中果皮）的主要特征与电磁共振模式的电场和磁场分量显示出明显的相关性。鉴于发育器官中共享的模式特征以及由具有与葫芦科器官相似几何和电学特性的建模结构支持的电磁共振模式，有必要进行实验研究。发育中的器官作为电磁介质谐振器的概念可能扩展到许多生命系统中的各种形态发生现象。
