In this study, we proposed the use of bOCT to monitor seed germination under the exposure of heavy metal micronutrient Zinc. The biospeckle OCT images revealed that there is a higher internal activity as indicated by red within the seed compared to control after 24h exposure of Zn. Further, depending on the concentrations, there is clear difference in the internal activity of the seed. Hence, our results confirm the positive impact of Zn on seed germination. Further studies are required to monitor different kinds of heavy metal stress on seed germination.
