Abstract

Monthly growth of a large brown alga, Undaria pinnatifida, was investigated during 5 months from November 2005 to March 2006 from a cultivation ground at Busan, Korea. A total of 10 character of Undaria were measured determine a reliable morphological character representing its growth of sporophytes. Plant weight of Undaria sporophytes increased steadily during the experimental period, the maximum weight was recorded as 9,344.6 g m-1 rope in March 2006. The optimal condition of their growing corresponded to that when the seawater temperature was decreasing and just before the coldest period of the year. Plant weight was positively correlated and fitted well with frond length, stipe length and midrib width. We suggest that plant weight with frond length, stipe length and midrib width is the most feasible morphological character with which to estimate the growth of U. pinnatifida sporophytes in the cultivation ground.
