In vitro tissue culture as a tool for Croatian grapevine germplasm management

Abstract

In vitro culture makes it possible to carry out specific studies that would not be possible with whole plants grown in the field or in a greenhouse. Cryopreservation allows long-term preservation without metabolic changes in the plant material and cryotherapy can be efficient in virus elimination, which is a major scientific challenge.
The preculture media of cryopreservation protocols were evaluated on three Croatian grape varieties with different antioxidants (salicylic acid, ascorbic acid and glutathione). The highest growth in vitro was achieved on the medium with the addition of glutathione and the lowest with the addition of salicylic acid. Growth in vitro and regeneration after cryopreservation depended on genotype and health status. The cryopreservation protocols tested (as part of cryotherapy) did not result in sufficient regeneration after cryopreservation (10-15%) in the varieties tested.
Virus elimination was tested for economically important viruses by meristem tip culture in 18 Croatian varieties. In vitro regeneration ranged 6.82-53.22%, but virus elimination was achieved in only three cultivars and was very low (23.8%). In addition, two new grapevine viruses (GVG and GBV-1) were tested. The results showed a low percentage of virus elimination (2%) by meristem tip culture in three-month-old tissue cultures.
Preliminary research activities were carried out by micrografting with Croatian grape varieties. The survival rate was good, but regeneration was difficult to achieve. A more detailed study is in progress. Overall, the presented methods of meristem tip culture, cryopreservation and micrografting should be further evaluated for the Croatian grapevine germplasm to enable wider application.

Innovative red winemaking strategy: biosurfactant-assisted extraction and stabilization of phenolic compounds

The color is the first attribute perceived by consumers and a major factor determining the quality of red wines. This depends mainly on the content of grape anthocyanins and their extraction into the juice/wine during winemaking. Furthermore, these compounds can undergo reactions that influence the chemical and sensory characteristics of the wine. Monomeric forms are prone to oxidation and adsorption on solid parts.

Terpenoids and norisoprenoids in italian red wines

AIM Terpene compounds are associated with floral notes and are characteristic of aromatic grape varieties such as Muscat (Jackson, 2008). They are generally considered to potentially contribute to the aroma of white wines. However, there is a growing interest towards the potential contribution of terpene compounds to the aroma of red wines. The aim of this work was to investigate the occurrence of different terpenes in red wines from Italian varieties. METHODS For this study wines from 11 mono-varietal Italian red wines from 12 regions were used (19 Sangiovese, 11 Nebbiolo, 10 Aglianico, 11 Primitivo, 10 Raboso del Piave, 9 Cannonau, 11 Teroldego, 3 Nerello, 9 Montepulciano, 7 Corvina). All samples were from vintage 2016 and none of them had been in contact with wood. A total of 19 terpenes and 7 norisoprenoids were analysed by mean of SPME-GC-MS analysis using a DVB-CAR-PDMS fiber. The wines were collected in the framework of the activities of the D-Wines (Diversity of Italian wines) project.

Implementation of a deep learning-based approach for detecting and localising automatically grapevine leaves with downy mildew symptoms

Grapevine downy mildew is a disease of foliage caused by Oomycete Plasmopara viticola an endoparasite that develops inside grapevine organs and can infect virtually every green organ. Downy mildew is one of the most destructive diseases in wine-growing regions, drastically reducing yield and fruit quality. Traditional manual disease detection relies on farm experts. Human field scouting has been widely used for monitoring the disease progress, however, is costly, laborious, subjective, and often imprecise.
