Abstract
The growth and characteristics of grapevines are influenced by numerous factors, including rootstocks, scions, vine training, climate conditions, field characteristics, and agricultural practices.
Therefore, it is essential to identify the most suitable rootstock-scion combinations tailored to each unique condition.
In this study, we assessed the growth and fruit set of two clones of ‘Muscat of Alexandria’ grafted onto the rootstocks 41 B and 140 Ru.
The experiment was conducted under a rain-fed regime in a field in La Marina Alta (Alicante, Spain), where this cultivar is representative.
The aim was to understand the effects of a dry year with anomalously high temperatures on the growth and fruit set of the rootstock-scion combinations under study.
The comparison of clones is also interesting as accumulated mutations and other changes may confer them with different abilities to acclimate to various environmental conditions.
To achieve our goal, several parameters, including fertility, budburst and flowering time, development of buds (phenological stages), vigor, fruit set, and berry quality, were measured.
Fruit set and fruit development were significantly affected in all rootstock-scion combinations, albeit to varying degrees, underscoring the importance of careful selection when choosing among them.
Berry analysis results are consistent with previous observations of differing ripening times between clones.
This work was funded by Generalitat Valenciana (grant CIAICO/2021/118) and contributes to the understanding of grapevine cultivation and adaptation.
