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.8.5805253.53327The Research Council of Norwayhttps://doi.org/10.13039/501100005416334327KELPRIME - Priming as a kelp engineering technology to enhance yield and secure production under environmental challenges
