Abstract

For improve the coloration of summer grapes, clusters of grafted 'Kyoho'(Vitis vinifera L. ×Vitis labruscana Bailey), tissue culture own-rooted 'Honey Red' (Vitis vinifera L. × Vitis labrusca L.) grapevines were treated with N-Propyl Dihydrojasmonate (PDJ) on the 37th day after full bloom. The results showed that anthocyanin accumulation on berry skin of PDJ 100 ppm treatment was heighter than that by 50 ppm treatment. PDJ treatments promoted berry coloration and TSS of juice, but there were not significant effects on acidity, berry size and chlorophyll content of berry skin as compared with the untreated one.為改善夏季葡萄著色不良之問題,本研究利用"巨峰"及"蜜紅"品種為材料,果穗在花後37日以(PDJ N-Propyl Dihydrojasmonate)處理後,探討對果實著色之影響。結果發現,以lOOppm處理顯著地促進果皮花青素的蓄積且糖度具上升之趨勢,有促進果實成熟的效果,而對酸度、果粒大小及果皮葉綠素含量則無顯著影響
