Dorstenia arifolia has mixed mating systems (xenogamy and geitonogamy), and is therefore self-compatible.
As examinations of the dipterans did not reveal any pollen grains adhering to their bodies, it is not likely that there was significant pollen transfer between flowers of the same plant (geitonogamy) or cross pollination (xenogamy) as a result of visits by those flies to C.
The percentage of flowers that formed siliques was highest in the free visitation treatment at Estrela and Esmeralda, while at Guarani das Missoes, the treatment showing the highest percentage of silique formation was xenogamy (see Table 1).
The reproductive system experiment included four pollination treatments: autogamy (A), geitonogamy (G), xenogamy (X), and open control (O).
Significance difference between the percentages obtained from xenogamy, autogamy and the control experiments were evaluated by comparison formula between two percentages, with a 5% significance difference level (PAGANO; GAUVREAU, 2004).
In the autogamy treatments and their control, 100% of the flowers aborted, while in the xenogamy treatment, 78.8% did so; that is, two out of nine flowers taken into consideration produced fruits.

Furthermore, self- and cross-pollinations resulted in similar numbers and mass of seeds (for selfing, 145.43 [+ or -] 18.12 seeds per capsule, n = 24; for xenogamy, 165.43 [+ or -] 16.31 seeds per capsule, n = 27; F = 0.417; df = 1, 49; NS; mean seed mass for selfing, 12 [+ or -] 0.1 [[micro]gram]; for xenogamy, 13 [+ or -] 0.1 [[micro]gram]; F = 2.104; df = 1, 49; NS).
