Summary
In red light at 15°C, female gametophytes of Laminaria saccharina continue to grow indefinitely without becoming fertile, but 6–12 hours' irradiation with blue light induces the production of eggs. At lower temperatures, some gametophytes become fertile in red light, but blue irradiation increases the percentage of fertile gametophytes.
