ABA 처리가 ‘파라다이스’ 포도의 착색과 과실품질에 미치는 영향

초록

‘Paradise’, a triploid grape cultivar, needs application of gibberellin acid in order to induce seedless fruit with large size, which can result in poor berry coloration under unsuitable growth conditions. Global warming leading to warm climates can be one of major reasons to prohibit production of ‘Paradise’ with high quality. Abscisic acid (ABA) is a well-known plant hormone that is related to the maturation of grape berries, and its application can be useful to avoid the problem of poor berry coloration. Hence, this study was conducted to investigate the effect of ABA application on fruit coloration and characteristics in ‘Paradise’ grape cultivar. ABA-treated berries were characterized by superior coloration compared to control berries. In addition, treatment with high concentration of ABA led to better fruit characteristics which result from early maturation. Therefore, ABA application seems to be an effective method for enhancing the fruit color and quality of ‘Paradise’ grape cultivar.
