| Abstract |
500 grains per flower. Pollen–ovule ratios within inflorescences averaged 196:1, suggesting facultative autogamy. Seed set in natural populations averaged 74%, not significantly different between early and late season plants or between greenhouse controls and hand pollinations. Emasculated plants produced small amounts of seed under controlled greenhouse conditions. Pollen tube growth through the styles of E. aquaticum, a related species, was much more prevalent than that of E. parkeri. Results suggest that E. parkeri relies heavily on geitonogamy for seed production. Some seed may be produced by agamospermy. |
