Abstract:
We here present data underlying a pilot study that investigated the effects of oligo-alginate elicitation on juvenile and adult sporophytes of Saccharina japonica cultivated in China and on adult sporophytes of Saccharina latissima cultivated in Germany. In two consecutive years, treatment with oligo-alginate clearly reduced the detachment of S. japonica juveniles from their substrate curtains during the nursery stage in greenhouse ponds (see data underlying Figure 1 https://doi.pangaea.de/10.1594/PANGAEA.896660). Oligo-alginate elicitation also decreased the density of endo-bionts on sporophytes of S. latissima that were cultivated on sea-based rafts (data underlying figure 3 https://doi.pangaea.de/10.1594/PANGAEA.896662). However, the treatment increased the susceptibility of kelp adults to settlement of epi-bionts (barnacles in Germany [data underlying figure 3 and data underlying figure 4 https://doi.pangaea.de/10.1594/PANGAEA.896662, https://doi.pangaea.de/10.1594/PANGAEA.896663] and filamentous algal epiphytes in China [data underlying figure 2 https://doi.pangaea.de/10.1594/PANGAEA.896661]). In addition, oligoalginate elicitation accelerated the aging of S. japonica adults [data underlying figure 2 https://doi.pangaea.de/10.1594/PANGAEA.896661].
