Abstract

In the present study, viticultural and oenological parameters of six clones of Muscat a Petits Grains Blancs (MPG) and five clones of Muscat giallo were investigated. Differences were found between varieties and clones in the occurrence of the phenological phases: bud break, véraison, and maturity. In the MPG clones (B41-5, FR 94, MPG 154, MPG 454, and MPG 455), all three phenological phases started earlier, resulting in earlier grape maturity and higher total soluble solids content (TSS) in grapes at harvest compared to the M. giallo clones (R1, VCR100, VCR 102, and VCR 5, BEMK 33). The MPG clones also resulted in higher cluster weight, higher yield per vine, and lower must pH compared to the M. giallo clones. The only exception was the MPG clone R2, which showed more similarities with the M. giallo clones. The wines of the MPG clones showed a tendency toward higher values for alcohol, citronellol, total acids, and total dry matter. In contrast, the wines of the M. giallo clones and the R2 clone of MPG showed higher pH and higher levels of linalool, α-terpineol, geraniol, and nerol. Although R2 is classified as a clone of MPG, our results indicate a strong similarity with the M. giallo clones studied. This study has highlighted the differences in phenological development and grape and wine quality characteristics between MPG and M. giallo clones. Therefore, clone selection can be an important tool for winemakers to develop the desired wine style and adapt to climatic changes.
马斯喀特小粒、白粒和马斯喀特无性系的葡萄栽培和酿酒特性
本文对6个马斯喀特小粒白(MPG)无性系和5个马斯喀特小粒白(giallo)无性系的葡萄栽培和酿酒参数进行了研究。不同品种和无性系在芽断期、青壮年和成熟期等物候阶段的发生上存在差异。在MPG无性系(B41-5、FR 94、MPG 154、MPG 454和MPG 455)中,与M. giallo无性系(R1、VCR100、VCR 102和VCR 5、BEMK 33)相比,所有三个物候阶段都开始得更早,导致葡萄成熟更早,收获时葡萄的总可溶性固形物含量(TSS)更高。MPG无性系的单株重、单株产量和土壤pH值均高于其他无性系。唯一的例外是MPG克隆R2,它与M. giallo克隆表现出更多的相似性。MPG无性系葡萄酒的酒精、香茅醇、总酸和总干物质含量呈较高的趋势。相比之下,MPG的R2无性系和giallo无性系的葡萄酒pH值较高,芳樟醇、α-松油醇、香叶醇和橙花醇含量较高。虽然R2被归类为MPG的克隆,但我们的结果表明它与所研究的M. giallo克隆有很强的相似性。本研究强调了MPG和M. giallo无性系在物候发育和葡萄及葡萄酒品质性状上的差异。因此,克隆选择可以成为酿酒师开发所需葡萄酒风格和适应气候变化的重要工具。
