Seed Coat Structural and Permeability Properties of Tilia miqueliana Seeds
2021
Wu, Yu | Shen, Yong Bao
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.
