Once the fruits and seeds have been collected inside the germplasm collection tubes, the existing residual moisture can diffuse through the polyurethane foam to the desiccant at the bottom of the tubes, being subsequently captured in the silica gel spheres. With indicator, depending on the amount of humidity present, the spheres change color to a green tone, which indicates that they have carried out their activity properly.
Simultaneously, the antimicrobial activity of the silver nanoparticles exerts a protective activity, reducing the growth of fungi during the storage of germplasm inside the polypropylene tubes by carrying out a fungistatic and fungicidal activity.
