Abstract

Experiments were carried out to asses the impotance of environmental conditions upon the growth rate, length compositions seedling and spore liberation of a red alga Glacilaric verrucosa. The alga grown in water of low salinity mixed with fresh water shows better growth rate, lager length composition and excellent seedling, whereas the one vegetated in an area of tidal exposure shows a somewhat retarded growth rate and poor seedlings. The rate of growth Increases from August to October and begins to diminish from December continuing to diminish through February. Therefore the spore settling time extends from May to lune. Although the sun-drying method is the most eacient way of inducing spore liberation, further investigations are necessary in oiler to use this method for the application to artificial spore settling.

1. 꼬시래기의 환경에 따른 체장조성, 포자방출유발방법에 대한 성적, 야외채묘성적 및 채묘기별의 성장도를 조사하였다. 2. 간조시에 완전히 노산되는 곳보다는 담수나 해수에 잠길 수 있는 요소나, 물이 흐르는 곳이 성장이나 채묘가 잘 되고 체장조성도 크다. 3. 가을($8\~10$월)에는 성장이 빠르나 겨울($12\~2$월)에는 거의 성장이 안되므로 채묘시기는 $5\~6$월이 알맞다. 4. 포자방출 유발방법에는 일건방법이 가장 효과가 크지만 인공채묘에 활용하기 위해서는 더 연구가 되어야 하겠다.
