Abstract

This study investigated the growth and maturation of free conchocelis of Pyropia yezoensis under monochromatic light of blue light(480 nm), green light(550 nm), yellow light(600 nm) and red light(730 nm) which measured the colony diameter, content of chlorophyll a and conchosporangium formation. In the result, the most of colony diameter and chlorophyll a showed under the blue light, $2,472.6{\pm}27.0{\mu}m$ and $1.55{\pm}0.03mg\;g.dw^{-1}$. Also, the chlrophyll a content of conchocelis was under the blue light. Therefore, the blue light might be favorable for the growth and maturation of conchocelis of P. yezoensis. This study will lead development of indoor culture technologies.

본 연구는 방사무늬김(Pyropia yezoensis) 사상체의 생장에 대한 단색광의 영향을 연구하기 위해 blue light(480 nm), green light(550 nm), yellow light(600 nm) and red light(730 nm)에서 방사무늬김(P. yezonesis)의 유리 사상체를 배양한 후 colony 직경, chlorphyll a 함량, 각포자낭 형성률을 측정하여 생장특성을 비교 분석하였다. 그 결과, colony 직경과 chlorophyll a 함량이 480(blue light) nm에서 각각 $2,472.6{\pm}27.0{\mu}m$ and $1.55{\pm}0.03mg\;g.dw^{-1}$로 최대값이 나타났고 각포자낭 형성률 역시 $37.87{\pm}1.08%$로 blue light에서 최대값으로 확인되었다. 따라서 blue light는 다른 단색광(green, yellow, red light)에 비해 김 사상체의 성장 및 성숙을 촉진하는 데에 효과적으로 작용하며, 본 연구결과는 향후 김의 실내 양식 기술 개발에 활용될 수 있을 것이라 사료된다.
