Abstract:
We examined the effect of gametophyte priming on early life stages of Saccharina latissima (juvenile sporophyte growth) in a laboratory experiment: we primed S. latissima gametophytes (Lofoten 2023; 15°C clonal culture; n = 7) for 3 weeks at 0°C, 10°C, and 20°C and induced gametogenesis at 10°C for 2 weeks. Resulting sporophytes reared at 10°C were subjected to a 14-day temperature gradient treatment spanning 7 temperatures (0, 5, 10, 15, 20, 21.5, 23°C). We measured sporophyte growth (length and relative growth rates) after 7 and 14 days. The laboratory Experiment was carried out at the Alfred Wegener Institute in Bremerhaven, Germany.
