In the present study, the structural and permeability properties of the Tilia miqueliana seed coat were primarily explored through the scanning electron microscope (SEM), transmission electron microscope (TEM), paraffin section detection (PSD), magnetic resonance imaging (MRI) and germination experiments. This found that the seed coat of Tilia miqueliana seeds exhibits two functions. On the one hand, the seed coat exhibits poor water permeability. The complex multilayer seed coat function as a barrier to water, and the hard, dense cell structure prevents water permeability. On the other hand, the seed coat covers and protects the embryo, it is likely to impose dormancy or trigger germination by controlling water uptake.

Tilia miqueliana 种子的种皮结构和渗透特性

在本研究中，主要通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、石蜡切片检测（PSD）、磁共振成像（MRI）和萌发等手段探索了紫罗兰种皮的结构和渗透特性。实验。这发现 Tilia miqueliana 种子的种皮表现出两种功能。一方面，种皮表现出较差的透水性。复杂的多层种皮起到了防水的作用，坚硬、致密的细胞结构阻止了水的渗透。另一方面，种皮覆盖并保护胚胎，它可能通过控制吸水来强制休眠或触发萌发。
