Abstract

<p>無核栽培における四倍体の赤色系ブドウ品種'安芸クイーン'および'ルビーロマン'に対する成熟後期(ベレゾーン25~40日後)でのABA含有肥料処理が着色と果実品質へ及ぼす影響を調査した.本処理がベレゾーン期処理の際に生じる深色化,糖度の低下を発生させずにアントシアニン蓄積を増加させたことから,成熟後期におけるABA含有肥料処理の着色促進効果の有効性が確認された.本処理による着色促進効果は'ルビーロマン'と比べ'安芸クイーン'でより顕著に現れた.アントシアニンの蓄積およびその生合成に関わる転写調節因子VlMybA1-2およびVlMybA1-3と生合成酵素UFGTの遺伝子発現パターンを経時的に調査したところ,品種間差異がみられた.すなわち,'ルビーロマン'は,'安芸クイーン'と比較してこれらの遺伝子発現が成熟後期において高く推移しておりアントシアニンをより蓄積しやすい品種であることが示唆された.</p>

<p>The effects of abscisic acid (ABA)-containing fertilizer treatment at a late growing stage (from 25 to 40 days after véraison) on the color development and quality of tetraploid red grape cultivars 'Aki Queen' and 'Ruby Roman', undergoing seedless cultivation, were investigated. The treatments at the late growing stage promoted ideal coloration without negative effects such as over-coloration or a decrease in the sugar content, which indicated the beneficial effect of color improvement induced by this fertilizer treated at the late growing stage. The enhanced accumulation of total anthocyanins due to this treatment was more notable in 'Aki Queen' than in 'Ruby Roman'. Time-dependent anthocyanin accumulation and the expression of genes involved in anthocyanin biosynthesis and related transcription factors, VlMybA1-2 and VlMybA1-3, and expression of the enzyme UDP-glucose:flavonoid 3-<i>O</i>-glucosyltransferase (UFGT) revealed the difference between these cultivars: all values were higher in 'Ruby Roman' than in 'Aki Queen' at the late stage of berry development, suggesting that higher levels of anthocyanins are accumulated in 'Ruby Roman'.</p>
