Pollination in Gesneria rupincola The top image to the right is of fresh Gesneria rupincola pollen. Next is a young stigma from an unopened flower. The bottom image is of a mature stigma encrusted with pollen. Pollination occurred without human intervention. Gesneria, like many if not all plants, is autofluorescent: the plant cells and tissue, when excited by specific wavelengths of light, emit light in different wavelengths which our eyes see as color. |
