Impact of Japanese beetles (Popillia japonica Newman) on the chemical composition of two grape varieties grown in Italy (Nebbiolo and Erbaluce)

Abstract

The Japanese beetle, Popillia japonica Newman, is considered one of the most harmful organisms due to its ability to feed on more than 300 plant species. Symptoms indicative of adult beetles include feeding holes in host plants extending to skeletonization of leaves when population numbers are high. The vine is one of the species most affected by this beetle. However, the damaged plants, even if with difficulty, manage to recover, bringing the bunches of grapes to ripeness.

The idea of this study was to chemically characterize both grapes produced from healthy plants and those obtained from damaged plants. The purpose was to highlight how the plant was able to respond positively or negatively after its leaf surface has been heavily damaged by the beetle.

Nebbiolo (red) and Erbaluce (white) are the V. vinifera L. cultivars selected for this study. These were harvested in three different sampling points, during the last phase of berry development (vintage 2020) from the vineyard located in the Northern part of Piedmont Region. Samples collection was conducted on August 26th, September 3rd and September 9th, including both healthy and popillia-affected samples.
Both the phenolic and aromatic components were characterized in the samples for 93 analytical variables (58 VOCs, 22 phenolics, 13 anthocyanins) whose information has been subjected to statistical analysis.

To further understand the different between healthy and affected state, a PLS-DA model was built. A clear separation was observed between affected and healthy grapes independently of grape variety. From the data set used, 10 phenolics were identified with VIP score higher than 1.5, namely protocatechuic acid-O-hexoside, protocatechuic acid, hydroxy-caffeic acid dimer isomer 1, (E)-coutaric acid, (Z)-fertaric acid, procyanidin dimer, catechin, epicatechin, quercetin-3-O-glucuronide, and quercetin, which are the most significant analytes to explain the discrimination between affected and healthy grapes.

Quali cantine perle strade del vino

Tutte le cantine possono aprirsi al pubblico? Evidentemente si, nessuno può impedire ad un produttore di accogliere i turisti. Tutte le cantine possono far parte delle Strade del vino? No, perché la Strada del vino mette in gioco la reputazione della denominazione di origine alla quale è legata e le possibilità di sviluppo economico di un intero territorio.

Handbook of the charter of the universal holistic metaethics  sustainability 4.1c” for certification and warranty bio-métaétique 4.1c

Defined the new paradigm, the applied philosophy, the methodology, the algorithm of the “Charter for Universal Holistic MetaEthic Sustainability 4.1C17.18”, research has continued to define and write, an
handbook that should be:”Complete Universal Holistic MetaEthics 4.1C of descriptors” of the “Charter for Sustainability Universal Holistic MetaEthic 4.1C17.18” with basic and applicative indexing. In these activities and research we have involved over 3500 Italian and non-Italian people from the research world to simple but educated, enlightened and enlightening citizens and we have analyzed over 180000
entries concerning the descriptors above, which represent the basic “descriptors”.

The role of tomato juice serum in malolactic fermentation in wine

Introduction: Malolactic fermentation (MLF) is a common process in winemaking to reduce wine acidity, maintain microbial stability and modify wine aroma. However, successful MLF is often hampered by their sluggish or stuck activity of malolactic bacteria (MLB) which may be caused by nutrient deficiency, especially when MLB are inoculated after alcoholic fermentation (Alexandre et al., 2004; Lerm et al., 2010). Identification and characterization of essential nutrients and growth factors for MLB allows for production of highly efficient nutrient supplements for MLF.

Étude de la cinétique de transfert du 2,4,6-trichloroanisole (TCA) entre des bouchons en liège naturel et le vin – premiers résultats

The last step in winemaking is packaging the wines for market placement, while preserving the quality attained during vinification. Since the 1980s, 2,4,6-trichloroanisole (TCA) has been recognised as an incidental and random contaminant of cork, with its migration into wine thought to contribute to ‘cork taint’. This molecule is not a cork component and little is known about how it is formed on trees. Its formation from the chlorine used to wash the cork stoppers, long suspected, has been excluded by the abandonment of chlorine washing.

Assessing macro-elements contents in vine leaves and grape berries of Vitis vinifera using near-infrared spectroscopy coupled with chemometrics

The cultivated vine (Vitis vinifera) is the main species cultivated in the world to make wine. In 2017, the world wine market represents 29 billion euros in exports, and France contributes 8.2 billion (28%) to this trade, making it a traditional market of strategic importance. Viticulture is therefore a key sector of the French agricultural economy. It is in this context that the nutritional diagnosis of the vine is of real strategic interest to winegrowers. Indeed, the fertilization of the vine is a tool for the winegrower that allows him to influence and regulate the quality of the wine.
