This study aimed to assess the impact of two soil managements and training systems on yield and wine aroma compounds of Negroamaro variety grown in a warm climate region (southern Italy). Cover crop (CC) and soil tillage (ST) as soil management, whilst bilateral Guyot (BG) and monolateral Guyot (MG) as training systems were compared. Free and bound volatile fractions were evaluated by GC-MS. ST and CC as well as BG and MG significantly affected yield parameters. In particular, yield was higher in ST and BG than in CC and MG, respectively; moreover, it was found to be positively influenced by interaction between BG and ST. Regarding aroma compounds, significant interactions between soil management and training system factors were observed. In case of free volatiles, the most positive interaction was found between BG and ST, whereas, for bound volatiles, the best interaction was represented by MG with both soil tillage and cover crop. Vine leaf area and development over vine growth stages along with water stress levels played an important role in determining the aroma profile as well as yield parameters. In conclusion, the training system significantly interacted with soil management and affected most of important aroma compounds in Negroamaro wine.
本研究旨在评估两种土壤管理和整枝系统对生长在温暖气候地区（意大利南部）的黑曼罗葡萄品种的产量和葡萄酒香气化合物的影响。比较了作为土壤管理方式的覆盖作物（CC）和土壤耕作（ST），以及作为整枝系统的双边居由式（BG）和单边居由式（MG）。通过气相色谱-质谱联用仪（GC-MS）对游离和结合挥发性成分进行评估。ST和CC以及BG和MG对产量参数均有显著影响。具体而言，ST和BG的产量分别高于CC和MG；此外，发现产量受到BG和ST之间相互作用的积极影响。关于香气化合物，观察到土壤管理和整枝系统因素之间存在显著相互作用。对于游离挥发物，BG和ST之间的相互作用最为积极，而对于结合挥发物，MG与土壤耕作和覆盖作物的相互作用最佳。葡萄叶片面积和整个葡萄生长阶段的发育以及水分胁迫水平在决定香气特征和产量参数方面发挥了重要作用。总之，整枝系统与土壤管理显著相互作用，并影响了黑曼罗葡萄酒中大部分重要的香气化合物。
