Abstract

Outdoor cultivation experiment was conducted with artificial seeds using free-living gametophytes and zoospores of Ecklonia cava to develop FLG (free-living gametophyte) seeding technique. Growth of thalli between FLG and zoospore seeding groups was compared monthly from May to October 2009 at culture farm in Wando, Korea. In September 2009, thalli in the FLG seeding experimental group were $35.9{\pm}0.8$ cm in length, $24.1{\pm}2.62$ g in weight, $2.32{\pm}0.26$ kg $m^{-1}$ in biomass and $22.0{\pm}2.8$ individuals $m^{-1}$ in density. There were no significant differences in length, weight, biomass and density between FLG and zoospore seeding group. Therefore, the FLG seeding technique could replace the zoospore seeding method which would eventually contribute in restoration and conservation of natural resources.

감태의 인공채묘시 유주자 및 유리배우체를 채묘하여 양성 생장도를 비교하므로써, 유리배우체의 대량양식 이용 가능성을 시험하였다. 2008년 11월에 유주자 및 유리배우체를 채묘한 채묘틀을 이용하여 2009년 5월부터 10월까지 전남 완도군 약산면 시험어장에서 양성 생장도를 비교하였다. 유주자 및 유리배우체 채묘 실험구에서 감태 엽체의 엽장과 생체량 등은 유의한 차이를 보이지 않았다.
