초록

톳의 유성생식을 통한 인공종묘생산 방법을 확립하기 위하여 초기 생장에 미치는 조도, 광주기 및 온도의 효과를 연구하였다. 각기 다른 조도 (500, 1,000, 2,000, 4,000, 8,000 lux), 광주기 (8 : 16, 12 : 12, 16 : 8 (L : D))와 온도 (10, 15, 20, 25, $30^{\circ}C$) 조건에서 유배를 70일간 배양한 결과 초기 생장 단계의 최적 조건으로는 조도 2,000-4,000 lux, 광주기 16 : 8 (L : D)와 온도조건으로는 15-2$0^{\circ}C$가 효과적인 것으로 나타났다.

Abstract

Effects of light and temperature on the early growth of Hizikia fusiformis were investigated for establishment of artificial seed production. Young germlings were cultured for 70 days under different culutre conditions : light intensities (500, 1, 000, 2, 000, 4, 000, 8, 000 lux), photoperiods (8 : 16, 12 : 12, 16 : 8, (L : D)) and temperatue (10, 15, 20, 25, $30^{\circ}C$). Growth of the germlings was facilitated in 2, 000~4, 000 lux of light intensities, 16 : 8 (L:D) of photoperiods and 15~$20^{\circ}C$ of temperature. Culture conditions were revealed for the mass culture of artificial seeds of effective early growth in Hizikia cultivation.
