Changes of Fruit Quality and Anthocyanin Composition of ‘Kyoho’ and ‘Heukboseok’ Grape Berry Skins under High Temperature at Veraison

Abstract: 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.Additional key words : poor coloration, anthocyanidin, acylation, abnormal high temperature 서 론 과피의 색은 포도의 품질을 결정하는 중요한 요소 중 의 하나이다.착색계 포도의 과피 색은 안토시아닌의 함 량 및 조성에 의해서 달라지며(Castellarin과 Gaspero, 2007), 이는 품종 고유의 유전적인 특성 및 환경적인 요 인에 의해 결정된다(He 등, 2010b).안토시아닌은 당과 배당체인 안토시아니딘의 결합으로 합성되며, 포도에는 pelargonidin(Pel), cyanidin(Cya), delphinidin(Del), peonidin(Peo), petunidin(Pet), malvidin (Mal)의 6가지의 안토시아니딘이 존재한다(Holton과 Cornish, 1995).이 중에서 Mal이 대부분의 품종에서 가장 많은 비 율을 차지하며, Pel은 극히 적은 양으로 존재하여 일반 적으로 관찰되지 않는다(He 등, 2010a
