 note = {application/pdf, 三重県志摩半島，浜島沿岸のカジメ藻体における相対生長の季節変化を比較・検討し，次のような結果を得た。 1） カジメの茎長に対する茎部･葉部および個体重量との間には，それぞれの組合せで明瞭な相対生長関係が成立することが認められた。 2） 茎長と茎径との関係は，茎径の値に上限値をもつ拡張相対生長式で表わすことができた。 3）生長輪数は3輪まで認められた。また，生長輪の形成時期は，11月頃から3月までの間と考えられる。 4） 各輪群ほ年級群として把握することができ，各年級群の季節変化から，更新の様相が明らかにされた。 5） 茎長は藻体各部との間に相対生長関係が成立することや測定が容易であることなどから，群落構造を解析する基準形質として適切と思われる。, Ecklonia cava is widely distributed along the Pacific coast of central Japan, and forms a dense marine forest on the rocky bottom. In the present report, seasonal changes in the relation between the length and diameter of stipe and the weight of stipe, blade and frond, respectvelly, were compared to obtain the primary data for analyzing the structure of the Ecklonia population. The materials examined were collected seasonally at a depth of 8m, in the coastal area of Hamajima, at the mouth of Ago Bay, Mie Prefecture. 
 There is an allometric relation between the length of stipe and the weight of stipe, blade and frond, respectivelly. The allometry of these was continuous. The equations for stipe weight to stipe length were regular nearly all the year round, but those for blade weight to stipe length varied seasonally. This clearly shows that the seasonal changes in frond weight depend on the changes in blade weight. 
 The allometric relation was not observed between stipe diameter and stipe, blade and frond weight, respectivelly. The relation between stipe length and stipe diameter was represented by extended allometric equations which had the upper limit of stipe diameter. 
 From one to three growth rings were counted among the materials collected, and each ring group was distinguished from another in the figure of allometry. The growth rings were formed from about November to March. The growth rings are definitly a reliable meaure of age. 
 It was confirmed that the stipe length is the most suitable standard factor for analyzing the Ecklonia population considering the relation between stipe length and other parts of the frond, and because of the ease it affords in measuring unter water.},
