Abstract:

【Objective】 To analyze the differences of botanical characters, berry quality, raisin polyphenols and antioxidant activity between Thompson Seedless and long-berry Thompson Seedless grape in the hope of providing new germplasm resources for grape breeding.【Methods】 V.vinefera cv.Thompson Seedless and bud mutation Long-berry Thompson Seedless were used as material, in the open field of the experimental vineyard,to investigate botanical character, photosynthetic response curve, berry quality and raisins quality and analyze the relationship between phenolic and antioxidant activity of raisins.【Results】 The results showed that, the main variation characteristics of bud mutation Long-berry Thompson Seedless were the color of young leaves, tender tips and petioles.Compared with ordinary Thompson Seedless, the color of young leaves was green with red bands, ventral new shoot color was green with red bands, dorsal internode color was green with red bands, and intersegmental ventral was green with red band.Germination rate of Thompson Seedless was higher than Long-berry Thompson Seedless, which were 65.00% and 63.82% respectively, germination rates of Long-berry Thompson Seedless were 50.48% and 53.45% respectively, in 2022, in 2023.The shape index of Long-berry Thompson Seedless were always higher than that of Thompson Seedless, the maximum shape index of Thompson Seedless and Long-berry Thompson Seedless were 1.80 and 2.12, after 16 d and 28 d after flowing, respectively.Berry quality, reduce sugar, sugar-acid ratio of Thompson Seedless were significantly higher than those of Long-berry Thompson Seedless, and there were no difference for bunch weight, bunch length, bunch width, soluble solid, titratable acid, Vitamin C, chromatic aberration.Drying rate, mean weight of Thompson Seedless were significantly higher than those of Long-berry Thompson Seedless, shape index of Long-berry Thompson Seedless was significantly higher than that of Thompson Seedless.Total flavanol, total flavonoids, total tannin, total phenol of Long-berry Thompson Seedless were significantly higher than those of Thompson Seedless, and their content were 1,808.59、2,286.43, 51.11, 98.53 mg/kg, respectively.DPPH and FRAP free radical scavenging capacity of Long-berry Thompson Seedless were significantly higher than Thompson Seedless, ABTS free radical scavenging capacity of Long-berry Thompson Seedless lower than Thompson Seedless, and no difference.The correlation coefficient were greater than 0.926 for total flavanol, total flavonoids, total tannin, total phenol, DPPH and FRAP free radical scavenging capacity, and their differences were significant or extremely significant.ABTS free radical scavenging capacity was negatively correlated with total flavanol, total flavonoids, total tannins, total phenols, DPPH and FRAP free radical scavenging capacity with litter difference.【Conclusion】 Bud mutation Long-berry Thompson Seedless can be used as an excellent variety and provide new germplasm resources for breeding.

摘要:

【目的】 分析无核白和芽变长粒无核白(长粒无核白)葡萄之间的植物学性状、果实品质、葡萄干多酚和抗氧化活性的差异,为葡萄育种提供新的种质资源。【方法】 以无核白葡萄及芽变长粒无核白为试材,调查植物学性状、光合响应曲线、果实品质和葡萄干品质差异,分析葡萄干酚类物质和抗氧化活性之间的关系。【结果】 长粒无核白葡萄主要变异特征表现在嫩叶、嫩梢、叶柄颜色和果粒上。与普通无核白相比,长粒无核白葡萄幼叶正面颜色绿色带红条带,新梢腹侧颜色绿带红条带、节间背侧颜色绿带红条带、节间腹侧绿带红条带。无核白萌芽率高于长粒无核白,其萌芽率分别为65.00%(2022年无核白)、63.82%(2023年无核白)、50.48%(2022年长粒无核白)、53.45%(2023年长粒无核白)。在整个果实发育期间,长粒无核白的果形指数始终显著高于无核白,花后16 d无核白葡萄的果形指数最大是1.80,而长粒无核白果实的果形指数在花后28 d达到最大,为2.12。长粒无核白果粒质量、果实还原糖含量、糖酸比显著高于无核白。无核白和长粒无核白果穗质量、果穗长度、果穗宽度、果实可溶性固形物、可滴定酸、VC和果皮色差差异不明显。无核白的出干率、平均质量均显著高于长粒无核白,而长粒无核白的果形指数(3.10)显著高于无核白葡萄干(2.13)。长粒无核白葡萄干的总黄烷醇、总类黄酮、总单宁、总酚显著高于无核白葡萄干,长粒无核白葡萄干的含量分别是1 808.59、2 286.43、51.11和498.53 mg/kg。长粒无核白葡萄干的DPPH自由基清除能力、对Fe2+的还原能力显著高于无核白葡萄,长粒无核白葡萄干的ABTS自由基清除能力低于无核白葡萄干,但无显著差异。葡萄干总黄烷醇、总类黄酮、总单宁、总酚、DPPH自由基清除能力、FRAP(对Fe2+的还原能力)彼此之间的相关系数大于0.926,为显著或极显著差异,而ABTS和总黄烷醇、总类黄酮、总单宁、总酚、DPPH自由基清除能力和FRAP(对Fe2+的还原能力)呈负相关,但无显著差异。【结论】 生产上芽变长粒无核白葡萄可以作为优良品种开发利用,亦可为育种提供新的种质资源。
