Control. The image shows the results after 15 days in humid chamber conditions with high relative humidity.

Manvert treatment. Roses in better condition.

Control. Image of the external surface of the rose petal extracted by scanning electron microscopy in an area of 1cm².

Manvert treatment. Greater homogeneity of the structure.

Control. Images of the external surface of the leaf of the rose crop extracted by scanning electron microscopy in an area of 1 cm².

Manvert treatment. Increased number of pubescences. These structures act as a protection, allowing the tissue to adapt to changes in the environment.

Control. Cross section of the leaf showing the cuticle of the epidermis seen by microscopy at 40x.

Manvert treatment. Greener palisade tissue. Greater quantity of chlorophyll, which implies a greater capacity to capture light.

Control. Image of flowers after 8 days post-harvest or vase life. Flowers with signs of senescence.

Manvert treatment. Flowers still vigorous.
