However, no detailed technical reports of seedling production by free-living gametophyte culture exist today for perennial species, the main component of kelp beds in temperate coastal regions of Japan (e.g., Eisenia bicyclis and Ecklonia cava). In fact, there is a technical bottleneck in their seedling production due to the difficulty in suppressing the maturity of gametophytes to synchronize fertilization. This report describes the method for free-living gametophyte culture of these species by demonstrating a case example of E. bicyclis seedling production, which includes applying Fe-free medium to suppress the maturity of gametophytes.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"近年，藻場の大幅な減少や気候変動の解決策としてのブルーカーボンへの期待から，大型海藻類の種苗生産の需要が世界的に高まっている。コンブ類やワカメの種苗生産で用いられるフリー配偶体培養は効率的で気候変動に対して頑健な技術である。しかし，我が国温帯域の主要な藻場構成種である多年生褐藻類（アラメ，カジメ等）ではフリー配偶体培養による種苗生産に関する詳細な技術報告はなく，配偶体の受精を同期させるための成熟抑制方法に技術的隘路が存在している。本報告ではアラメ種苗生産の事例を示し，これらの種を対象としたフリー配偶体培養技術，特に鉄成分を含まない培養液による配偶体の成熟抑制方法の適用について記載した。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57348/0002012552","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan
