AGARDH and by setting campaus sheets around for embryo to settle down effectively in near natural Sargassum beds at Matugahana point, Towa town, Yashiro island of Hiroshima Bay. This campus sheets were used during 25 days from April 31 to June 25, 1984. The results obtained are as follows; 1). Young plants S. patens were found on the artificial reefs in about 2 months later, on August 28, 1984, and grew to thalli, thereafter. 2). New Sargassum beds were formed mainly by S. patens and were stabilized for 2 years. It was expanded slowly for the first year from August 28, 1984 to March 18, 1985, and the maxmium in standing crops of S. patens was 670 individuals/m2 and 3993.0g wet weight/m2 on February 1, 1985. These value were about 13 times as many in individuals and about 25 times as much in wet weight as in the community of natural Sargassaceae on artificial reefs. However, many plant grew slowly in the second years from May 28, 1985 to May 15, 1986, and the maxmium in stauding crops of S. patens was 260 individuals/m2 and 194.0g/m2 on December 19, 1985. These value were about 5 times as many in individual and about double times as much in wet weight as in the community of natural Sargassaceae on artificial reefs. 3). The ratio of S. patens to all Sargassaceae was the range of 67 to 98 % in density and 92 to 98 % in wet weight in about one year. It was 79 to 100 % in density and 53 to 100 % in wet weight in about second years. 4). The maximum in mean length of main shoot of S. patens was 24.4 cm and the maximum in wet weight was 6.0 g on Februaly 1, 1985. 5). From the results mentioned above, this method was assumed to be effectual means of forming Sargassum beds. Because, it was useful for embryo to settle down and prevent another species of embryo from invading.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"山口県大島郡東和町伊保田松ヶ鼻地先において,多年生ヤツマタモクを造成対象種として選定し,その移植親藻から放出される幼胚の着生を確実にし,かつ他種類の混入を防ぐために,キャンパスシート囲枠を用いた幼胚集積法により単一優占群落の造成試験を行った。幼胚集積期間は1984年5月31日から6月25日までの25日間とした。その結果,以下の知見を得た。1).藻礁設置後約3カ月を経た1984年8月28日にヤツマタモクはすでに幼体となって藻礁上に多数着生した。2).ヤツマタモクは藻礁に優占群落を形成した。その現存量は,1年目の最繁茂期となる1985年2月1日には生育密度が670個体/m2,湿重量が3,993.0g/m2,2年目の最繁茂期となる1986年5月15日には240個体/m2,183.0g/m2になった。この現存量を同一時期に幼胚の着生を天然に委ねた対照藻礁に比べると,1年目の最繁茂期に生育密度では約13倍に,湿重量では約25倍に,同様に2年目最繁茂期では約5倍と約2倍になった。3). ヤツマタモクが全ホンダワラ類に占める個体数と湿重量の割合は,群落形成初期から最繁茂期を経て,藻体の枯死流失が始まる1985年5月までの間(1年目)では,個体数が67~98%,湿重量が92~98%の範囲で推移し,また,群落再形成が始まる1985年8月から再び群落が再繁茂する1986年5月までの間(2年目)では同様に79~100%と53~100%の範囲で推移した。4).着生したヤツマタモクは1,2年目とも藻体の伸長が比較的緩慢で,生長がやや悪かった。藻体が最大となったのは1985年2月で,その個体平均主枝長は24.4cm,個体平均湿重量は6.0gであった。5).本幼胚集積法は藻礁設置域が一時的にブール化されることによって,幼胚の着生が確実かつ効果的に図られるとともに,幼胚の拡散を妨げ,他種ホンダワラ幼胚の混入をも防止するので藻場造成手法として有効であると考えられる。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nnf_k_21_25","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010371436","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Yoshikawa, Koji","creatorNameLang":"en"},{"creatorName":"吉川, 浩二","creatorNameLang":"ja"},{"creatorName":"ヨシカワ, コウジ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Yoshikawa","familyNameLang":"en"},{"familyName":"吉川","familyNameLang":"ja"},{"familyName":"ヨシカワ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Koji","givenNameLang":"en"},{"givenName":"浩二","givenNameLang":"ja"},{"givenName":"コウジ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2781","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ホンダワラ藻場造成に関する研究 (3)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ホンダワラ藻場造成に関する研究 (3)","subitem_title_language":"ja"},{"subitem_title":"Studies on the Formation of Sargassum Beds-III.
