영문 초록

Comparative study was made on absorption spectra (300-750 ㎜) of water extracts centrifuged (5,000 rpm, 5min.) of the sporothallus of the wild-type (U-511) plant, and the red-type (H-25), the green-type (C-O giant), the yellow-type (ZY-1), the violet-type (ZV-1), the gray-type (ZGr-1), the light red-type (ZLR-1), the light green-type (C-31) and the light yellow-type (ZLY-1) mutants in P. yezoensis. The absorption was recorded with a double monochrometer recording spectrophotometer (Hitachi U-3210) not equipped with an integrating sphere attachment or a head-on photomultiplier. The wild-type plant and the red-, the green-, the violet- and the light red-type mutants showed the spectra having a maximum in near ultraviolet region (300-400 ㎜), indicating the presence of the ultraviolet absorbing substance. The wild-type plant and the red-, the green-, the yellow- and the violet-type mutants showed the spectra having two absorption maxima in 530-580 ㎜ region. The yellow- and the gray-type mutants had the spectra with markedly low absorption in a 300-750 ㎜ region. The violet- and the gray-type mutants were characterized by higher PE/Chl. a and PC/Chl. a ratios. The light green-type mutant was marked by lower PE/Chl. a and PE/PC ratios, while the light yellow-type by higher PE/Chl. a and PE/PC ratios. The light red-type mutant was featured by higher PE/Chl. a and PE/PC ratios and by lower PC/Chl. a ratio. It is inferred : that the light green- and the light yellow-type mutants might result from qualitative and quantitative variations of phycoerythrin ; that the gray- and the light red-type mutants might originate from qualitative variation of phycoerythrin and quantitative variation of chlorophyll a and phycocyanin; that the violet-type mutant might arise from quantitative variation of chlorophyll a; that the yellow-type might stem from quantitative variation of phycocyanin.
