Methyl jasmonate versus nano methyl jasmonate: effects on anthocyanins mature evolution in monastrell grapes

Abstract

AIM: The climate change is afecting particulary to the South of Spain, with high temperatures. It is important to develop new strategies in order to mantain the quality of wines. One of this strategies is the use of elicitors which increase the defense in plants and also increase the content of secondary metabolites, such as anthocyanins . On the other hand, the use of use of nanoparticules joined to methyl jasmonate could diminish the concentrations applied in plants but obtaining similar effects in Monastrell anthocyanins profile as using only methyl jasmonate.

METHODS: The treatments were carried out in an experimental vineyard of Monastrell located in South East of Spain, foliar application of each treatament, by triplicate, in verasion and a week later. The differents treataments were i) control, ii) methyl jasmonate and iii) nano methyl jasmonate (nanoparticles of hydroxyapatite doped with methyl jasmonate). A study of mature evolution was done, the samples were taken at the previous moment of the firts time treataments and every ten days and finaly in the moment of harvest. The analysis were performance by HPLC following the Gil Muñoz et al. (1) procedure.

RESULTS: The treatment with methyl jasmonate increased the anthocyanins composition in the differents points of maturation and also in the harvest moment. Similar results were obtained in the treatment with methyl jasmonate and hydroxyapatite doped with methyl jasmonate.

CONCLUSIONS

The used of nanotechnology in the treatments with methyl jasmonate would allow to reduce the dose of this elicitor obtaining similar results, in the way to reduce costs and contribute to a sustainable agriculture.

Carbon isotope ratio (Δ13C) and phenolic profile used to discriminate wines from Dealu mare and Cotnari regions (Romania)

Regarding the food quality, authenticity is one of the most important issues in the context of ensuring the safety and security of consumers, but is also more important when it comes to wine (one of the most counterfeited foods in the world).

Evaluation of a biological foliar fertilization system, in the production, agronomic and quality characteristics of three wine grape varieties

Evaluation of the fertility management practices in wine grape varieties production. Wine grape represents one of the most important productions in Greece with major impact to the socioeconomic characteristics of the country. The objective of this study is to evaluate, with the support of Geospatial Technologies, the potential effects of an innovative foliar fertilizer system, which is composed of three parts: a mineral fertilizer in a micronized formulation, a biostimulant as an enhancing factor of the process and, an amino acid compound (SANOVITA concept). The study was established at a collaborative, private vineyard, in the area of Trilofos-Thessaloniki, at the region of Northern Greece.

Evaluation of the enological potential of red grapes in southern Brazil

The Campanha Gaúcha is located in the pampa biome and has unique characteristics, as it is the hottest producing region with the lowest volume of rain in Southern Brazil. Furthermore, the large extensions of flat or low-sloping areas, harsh winters and great sunshine during the ripening period, made this the second largest producer of fine wines in Brazil.

Influence of edapho-climatic factors on grape quality in Conca de Barberà vineyards (Catalonia, Spain)

Soil and climate of 3 vineyards have been characterised in order to determine their influence on grape quality. These vineyards are located in Conca de Barberà (Catalonia, NE Spain) and belong to Cabernet sauvignon and Grenache noir cultivars. All 3 plots are very close, so only interannual climatic data of the nearest meteorological station have been considered.
