Abstract
Beyond pest resistance, rootstocks significantly influence the performance of grapevine varieties. However, the effect of the rootstock is strongly affected by its interaction with the environment, and it is therefore necessary to evaluate their influence in a particular terroir. With the aim of evaluating the influence of 12 rootstocks on the agronomic performance of 'Syrah' and 'Tempranillo', a trial was established in 2011 and 2012 in Miranda de Arga (Navarra, Spain), under the typical environmental conditions of the Ebro Valley. Growth and yield, as well as industrial and phenolic maturity parameters were analysed during four consecutive seasons (2015-2018). Most rootstocks showed a similar performance with both varieties, not always following the trends reported in bibliography, which highlights the relevance of studying rootstocks in different conditions. 3309 C was the rootstock conferring the highest vigour, whereas the lowest were provided by 420 A MGt and 'Fercal'. The implications on grape composition were much more diverse, and were partially conditioned by yield. Results were obtained during the four first harvests of the vineyard, and could therefore change to some extent as the vineyard reaches stability.
除了抗虫害外,砧木对葡萄品种的性能也有显著影响。然而,砧木的效果受其与环境的相互作用的强烈影响,因此有必要评估它们在特定风土中的影响。为了评估12种砧木对“西拉”和“丹pranillo”农艺性能的影响,2011年和2012年在西班牙纳瓦拉的Miranda de Arga进行了一项试验,试验条件是埃布罗河谷的典型环境条件。在连续四个季节(2015-2018年)对生长和产量以及工业和酚成熟度参数进行了分析。大多数砧木在两个品种中表现出相似的表现,并不总是遵循参考文献中报道的趋势,这突出了研究不同条件下砧木的相关性。3309 C的活力最高,而420 A MGt和‘Fercal’的活力最低。对葡萄成分的影响更加多样化,部分是由产量决定的。结果是在葡萄园的前四次收获期间获得的,因此随着葡萄园的稳定,可能会在一定程度上发生变化。
