Abstract:
We examined the effect of gametophyte priming on early life stages of Saccharina latissima (gametophyte growth and sporophyte recruitment) 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, during which we assessed relative gametophyte growth rates (from day 0 – 5), progression of gametogenesis, and sporophyte recruitment. The laboratory experimentwas carried out at the Alfred Wegener Institute in Bremerhaven, Germany.
