内容記述(抄録等)In the previous paper it was demonstrated that the summer-flowering gladiolus contained thirteen kids of anthocyanins which were derived from kinds anthocyanidins combined with three patterns of glycosylation. The present investigation was undertaken to uncover the anthocyanin constitution of the early-flowering gladiolus. The results obtained were summarized as follows; 1. Twelve kinds of anthocyanins were identified. They were pelargonidin-3-glucoside, pelargonidin-3-rhamnosylglucoside, pelargonidin-3, 5-diglucoside, pelargonidin-3-rhamnosylglucoside-5-glucoside, malvidin-3-glucoside, malvidin-3-rhamanosylglucoside, malvidin-3, 5-diglucoside, malvidin-3-rhamnosylglucoside-5-glucoside, petuidin-3-glucoside, petunidin-3-rhamnosylglucoside, petunidin-3, 5-diglucoside and petunidin-3-rhamnosylglucoside-5-glucoside. 2. Of these twelve anthocyanins, eight were in common with those of the summer-flowering strain and the remaining four were identified for the first time in this investigation. These newly identified were pelargonidin-3-glucoside, malvidin-3-glucoside, petunidin-3-glucoside and petunidin-3-rhamnosvlglucoside. 3. In the previous paper it was deduced that the 3-glucoside might be the key intermediate toward the more highly glycosylated anthocyanin in the pigment biosynthesis. In this experiment the 3-glucoside was disclosed to be actually present, thus supporting the previous deduction. And this presence of fourth pattern of glycosylation may extend the number of anthocyanins potentially occurring in this genus from eighteen to twenty-four. 4. The early-flowering gladiolus had essentially the same antocyanin constitution as the summer-flowering one, except for tha presence of 3-glucoside and much smaller amount of malvidin. This fact was interpreted to indicate that the pigmentation in the early-flowering strain is controlled by the similar but somewhat recessive genetic system as against that in the summer-flowering stain. 5. Concerning the mode of hydroxulation of anthocyanin some unusual features were encountered, i. e. the distribution pattern of anthocyanin in gladilus was different from such plants as Streptocarpus hybridus and Lathyrus odoratus whose anthocyanin constitution is determined through epistatic genetic system which prevents the co-occurrence of anthocyanins having different level of hydroxylation, and also different from such plants as Primula sinensis ans Impatiens balsomina whose anthocyanin in each individual is almost exclusively composed of delphinidin (malvidin) and/or pelargonidin. The more detailed feature will be presented in forthcoming paper.
