Abstract
Practical Implications of Different Phenotypic and Molecular Responses of Evergreen Conifer and Broadleaf Deciduous Forest Tree Species to Regulated Water Deficit in a Container Nursery
Highlights
Vine growing is closely associated to climatology, which means that climate change effects have become of great concern, promoting new research lines focused on the adaptability of the different grapevine varieties to the new scenarios [1,2]
The annual average mean temperature was similar in the Ribeiro and Ribeira Sacra regions (Table 1), it was slightly higher in the Ribeiro region in 2018 with 15.2 ◦C compared to 14.2 ◦C in Ribeira Sacra
In this vineyard and season, the 68% coulure value was reached by the Godello variety, which could have been due to environmental conditions since this variety usually express higher fruitset rates
Summary
Vine growing is closely associated to climatology, which means that climate change effects have become of great concern, promoting new research lines focused on the adaptability of the different grapevine varieties to the new scenarios [1,2]. The terroir characteristics, crop management practices (e.g., pruning, tillage, planting system, or irrigation), and the cultivated grapevine variety [5–7] are important factors to considered both independently and as a whole [8]. The genetic characteristics of the different grapevine varieties determine their resistance to frost and cryptogamic disease, such as powdery mildew, grey mold, or downy mildew, which can cause serious economic losses [9,10]. To know the host resistance is useful for the long-term management of the disease [12,13]. Fertilization-related aspects are determinants for crop production. The different grapevine varieties use distinct mechanism to ensure optimal ovary fertilization and fruit development. Pollen polymorphism, which is a widespread phenomenon among higher plants [20,21], could be related to the irregular productivity of some grapevine cultivars [19–22]
