A plant that can survive by increasing the salt concentration in the plant body and immersing it in seawater. In Japan, it grows in salt marshes (salt wetlands) along calm coastlines surrounded by sandbars. It is found not only in salt marshes but also in salt pools on reclaimed land and former salt fields. However, such places are becoming less common these days. Saltwo, Chishima Lojotuna, and Umimidori are found in Hokkaido, while Hamamatsuna and Narrow-leaved Hamaakaza are found throughout Honshu. Other representative halophytes include Shichimenso (northern Kyushu), Hamasaj (central and southern Honshu), and Fukudo (west of the Kii Peninsula). The beautiful autumn foliage of Saltwo on the shores of Lake Notoro in Hokkaido is well known. [Kazuo Kotaki] A lagoon with an area of 58.4 km2 located at the northwestern edge of Abashiri City. It is separated from the Sea of Okhotsk by a sandbar, but is a brackish lake that connects to the open sea at its northeastern end, where flatfish fishing and scallop farming are carried out. The Ubaranai area on the southwestern shore (photo) is known as a habitat for glasswort, and in early autumn the entire area is dyed red. It is part of Abashiri Quasi-National Park.

植物体中の塩分濃度を高くして、海水に浸っても生きていける植物。わが国では砂州で囲まれた波の静かな海岸沿いの塩沼地(塩湿地)に生育する。塩沼地だけでなく、干拓地や塩田跡地の塩だまりにもみられる。しかし現在では、このような場所が少なくなっている。アッケシソウ、チシマドジョウツナギ、ウミミドリなどは北海道に、本州各地にはハママツナ、ホソバノハマアカザなどが分布する。また、シチメンソウ(九州北部)、ハマサジ(本州中部以南)、フクド(紀伊半島以西)なども塩生植物の代表的なものである。北海道能取(のとろ)湖畔のアッケシソウの秋の紅葉は美しく、よく知られている。 [小滝一夫] 網走市北西端にある面積58.4kmの潟湖。オホーツク海とは砂州で仕切られているが、北東端で外海と通じる汽水湖で、湖内ではカレイ漁やホタテガイなどの養殖が行われている。南西岸の卯原内地区(写真)はアッケシソウの群生地として知られ、初秋には一面が赤く染まる。網走国定公園に含まれる。北海道網走市©網走市観光協会"> 能取湖(アッケシソウ群落) 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
