The re-emergence of Grapevine Trunk Diseases (GTDs), mainly Esca, has been observed in most the world’s vineyards during last two decades. Development necrosis grapevine wood, especially white-rot, is typically associated with Esca-diseased plants. One different methods being used attempts to eradicate GTDs curettage. This old cultural practice, which consists surgically removing necrotic speci...

The increasing adoption of dicamba-tolerant soybean ( Glycine max ) increases the potential exposure wine grape Vitis sp.) to dicamba, which off-target injury may occur via particle drift or vapor drift. In Missouri, at one site in 2017 and two sites 2018, research production vineyards focused on effects dicamba hybrid ‘Vidal blanc’ grapevines. During flowering early fruit set, bearing grapevin...

Background and Aims: Climate variation contributes to fluctuations in reproductive output, and spring temperature is thought to influence flower production in grapevines. For 3 years, we studied the influence of temperature from before budswell through to the appearance of individual flowers on reproductive development in field-grown Cabernet Sauvignon while minimising the influence of other mi...

The rhizosphere is where crucial processes for the productivity of viticultural systems occur. composition bacterial communities associated with grapevines known to depend on plant genotype. However, genotype grafted differs between scion and rootstock; role each unclear. To untangle effect rootstock, rRNA (V4–V5 region 16S rRNA) extracted from grape varieties Riesling Mueller-Thurgau ungrafted...

Climate change has the potential to impact agricultural sector and wine in particular. The impacts of climate are likely differ across producing regions wine. Future scenarios may push some into climatic regimes favourable grape growing production, with changes areas planted vines. We examine which is linkage between productivity levels global sector. Within framework supply response, we assume...

• Flower formation in grapevines follows 3 steps: 1) formation of uncommitted primordia, also called anlagen, within the latent buds; 2) differentiation of uncommitted primordia into inflorescence primordia; and 3) differentiation of inflorescence primordia into individual flowers . Steps 1 and 2 happen during the previous season, whereas Step 3 does not happen until budbreak of the current sea...

This chapter presents an overview of grapevine structure and function to provide a basic understanding of how grapevines grow. Such understanding is the foundation of good vineyard management, and the practical application of this knowledge is emphasized throughout this book. The reader should consult the references cited in this chapter for more complete coverage of these topics. Much of the c...

Burkholderia phytofirmans PsJN(T) is able to efficiently colonize the rhizosphere, root, and above-ground plant tissues of a wide variety of genetically unrelated plants, such as potatoes, canola, maize, and grapevines. Strain PsJN shows strong plant growth-promoting effects and was reported to enhance plant vigor and resistance to biotic and abiotic stresses. Here, we report the genome sequenc...
