  • Intersectional differences in anthocyanin composition were observed in a survey of floral anthocyanins of 27 species in genus Hibiscus (Malvaceae). The most common suits of floral anthocyanins were 3-xylosylglucosides and 3-glucosides of delphinidin and cyanidin in species of section Trichospermum, Fucaria, Trionum, Abelmoschus, and Ketmia. Cyanidin 3-sophoroside was the predominant anthocyanin in species of section Lilibiscus. Six common anthocyanidin 3-glucosides and corresponding malonates were detected only in the species of section Bombycella. These intersectional variation coincided generally with proposed sectional boundaries based on morphological characteristics. Anthocyanin composition was more complicated in self-incompatible species than in self-compatible species. The systematic significance of diverse anthocyanin profile was discussed in the aspect of pollination ecology.

  • We analyzed the skin coloration and anthocyanin composition of 'Kyoho' and 'Heukboseok' grape berries to determine the cause of poor coloring in 'Kyoho' berry skins under high temperature (HT) at veraison. Although the skin coloration inhibited in both 'Kyoho' and 'Heukboseok' berries under HT for 30 days from veraison, the total anthocyanin content in 'Heukboseok' berry skins increased to the level of control after the end of temperature treatment, but 'Kyoho' did not increase. Malvidin derivatives were most significantly reduced in 'Kyoho' berry skins, followed by those of delphinidin and petunidin. Among individual anthocyanins, diglucosides and acylated malvidin derivatives were most decreased in 'Kyoho' berry skins. Acylated and tri-hydroxylated anthocyanins were reduced more than those of non-acylated and dihydroxylated, respectively. All different types of anthocyanin components in 'Kyoho' berry skins decreased by HT, and they were similar to that of total anthocyanin. In 'Heukboseok' berry skins, accumulations of all different types of anthocyanins were inhibited by HT, and increased to the level of control after the end of the treatment. These results suggest that the poor coloration of 'Kyoho' under HT at veraison was not caused by the decrease of specific anthocyanins but because the whole anthocyanin biosynthesis was suppressed by HT.
