Examples of successful Japanese cherry red radish microgreen germination at Day After Planting (DAP) 7. (A) Post-experiment specimens grown using the oblate film method, showing successful germination and early development. (B) Close-up of healthy microgreens cultivated using the oblate film method.

Figure 3.

Seed Arrangement and Film Interaction with Agar Media. (A) Seeds arranged in a grid formation directly placed on the surface of the agar media. (B) Oblate film with adhered seeds upon contact with the agar media; the film adheres fully to the agar due to moisture, beginning to dissolve and ensuring the seeds establish direct contact with the moisture for germination.

Average Germination Percentage Comparison Between Control and Oblate Film. Bar chart illustrating the average germination percentages for Days After Planting (DAP) 1 and DAP 7. Data compare germination rates between seeds in the control group and seeds adhered to the oblate film. Error bars indicate standard deviation.

Seed encapsulated within oblate film, forming a seed pocket for optimized handling and germination. In the background, a mature cherry red radish plant grown from these seed pockets during preliminary testing is displayed, demonstrating the effectiveness of the encapsulation method.
