The effect of rust infection on reproduction in a tropical tree (Faramea occidentalis)
Fungal pathogens that infect reproductive structures of plants (e.g., flowers and fruits) can reduce the seed production and seedling recruitment of host plants. We report here on the effects of a rust, Aecidium farameae, that infects the ovaries and pedicels of mature flowers on Faramea occidentali...

| description | Fungal pathogens that infect reproductive structures of plants (e.g., flowers and fruits) can reduce the seed production and seedling recruitment of host plants. We report here on the effects of a rust, Aecidium farameae, that infects the ovaries and pedicels of mature flowers on Faramea occidentalis (Rubiaceae), a small tree common on Barro Colorado Island, Republic of Panama. Rust infection of ovaries reduced the number of maturing fruit on infected trees. Trees with low rust incidence in June of 1992 had 68 percent fruit survival, compared to 17 percent fruit survival for those with high rust incidence. Infected fruits developed abnormally and were usually aborted long before uninfected fruits were mature. One hundred percent of the infected ovaries marked in July were diseased or missing in August. We conclude that infection by A. farameae has the potential to seriously decrease the reproductive output of Faramea occidentalis and may represent an important source of variation in the relative fitness of individual plants. |
