After 13 days in culture, maximum gametophyte growths of the two species were obtained under the following combinations of factors: 17 6 μmol photons m 2 s 1 and 24 h daylength 6 μmol photons m 2 s 1. C. costata gametophytes produced sporophytes about 6 days earlier than those of U. pinnatifida. Sporophyte densities were highest in the 12 h daylength 6 μmol photons m 2 s 1 combination after days in C. costata (9.7 plants mm 2 ) and 26 days in U. pinnatifida (9.1 plants mm 2 ). However, optimal growth conditions for the microscopic sporophytes differed between species: 17 6 μmol photons m 2 s 1 for C. costata, 12 6 μmol photons m 2 s 1 for U. pinnatifida. Thus, C. costata gametophytes grew faster and produced sporophytes earlier than those of U. pinnatifida, even though the haploid gametophytes of the two species responded similarly to environmental conditions. Optimal growth temperatures for the microscopic sporophytes also differed between species.
