We demonstrate that optical coherence tomography (OCT) is a plausible optical tool for in vivo detection of plant seeds and its morphological changes during growth. To investigate the direct impact of salt stress on seed germination, the experiment was conducted using seeds that were treated with different molar concentrations of NaCl. To determine the optimal concentration for the seed growth, the seeds were monitored for nine consecutive days. In vivo two-dimensional OCT images of the treated seeds were obtained and compared with the images of seeds that were grown using sterile distilled water. The obtained results confirm the feasibility of using OCT for the proposed application. Normalized depth profile analysis was utilized to support the conclusions.
我们证明了光学相干断层扫描（OCT）是一种可行的光学工具，可用于在体内检测植物种子及其生长过程中的形态变化。为了研究盐胁迫对种子萌发的直接影响，该实验使用经过不同摩尔浓度 NaCl 处理的种子进行。为了确定种子生长的最佳浓度，连续九天监测种子。获得了处理后的种子的体内二维 OCT 图像，并将其与使用无菌蒸馏水生长的种子的图像进行了比较。所得结果证实了 OCT 用于该应用的可行性。归一化深度剖面分析用于支持结论。
