영문 초록

To advance seeding of conchospores of Porphyra dentata, P. seriata and P. tenera, the effects of light intensity and photoperiod on growth of shell-inhabiting conchocelis, and formation and maturation of conchosporangia were studied from May to October in 1998. Growth of shell-inhabiting conchocelis of these species was similar to one another in early culture under natural light intensity, photoperiod and room temperature; growth of P. dentata and P. seriata was higher than that of P. tenera at 800 lux from August to September; growth of these three species was similar to one another at 800 lux in October. The color of shell-inhabiting conchocelis of P. dentata and P. seriata was red and the color of P. tenera black, but all the species were reddish-purple after mid-september. Formation rate of conchosporangia was 90% or more in P. tenera, 70% in P. seriata and less than 40% in P. dentata at September. Maturation of conchosporangia under 500 and 800 lux was better than 1,500 lux in the three species. Numbers of released conchospores were more at 18℃ than at 22℃, and the short-day treatment(8L:16D) gave rise to promotion of conchospore release. Numbers of conchospore germlings attached 1 ㎝ long netting-twine after 30 days of seeding were 35 individuals in P. tenera, 10 individuals in P. seriata and 3 individuals in P. dentata. Attached germlings of P. seriata were increased after 45 and 60 days; it suggests that monospores might be released
