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.

The relationship of wine store customers with the areas of production, considering provenance and tourism

This work aims at identifying the most appropriate marketing strategies to inform consumers of the global market about the added value of the wines of Friuli Venezia Giulia.

Modification on grape phenolic and aromatic composition due to different leafroll virus infections

Viral diseases are reported to cause several detrimental effects on grapevine. Among them, leafroll, due to single or mixed infection of GLRaV1 and GLRaV3, and rugose wood, associated to GVA, are considered the most widespread and dangerous.

Autochthonous non-Saccharomyces extra-cellular metabolism of tryptophan, tyrosine, and phenylalanine

Amino acids are crucial nitrogen sources in yeast metabolism, influencing both biomass production and fermentation rate. The breakdown byproducts of amino acids contribute to the aroma of the wine and wine’s health benefit compounds. This study focused on the yeast’s extracellular metabolic profile of tryptophan, tyrosine, and phenylalanine belonging to the group of aromatic amino acids in experimental Maraština wines. Alcoholic fermentations were conducted on sterile grape Maraština must using seven autochthonous non-Saccharomyces yeasts in sequential fermentation with commercial Saccharomyces cerevisiae.

The surprising role of VvLYK6 in grapevine immune responses triggered by chitin oligomers

For sustainable viticulture, the substitution of chemical inputs with biocontrol products has become one of the most considered strategies. This strategy is based on elicitor-triggered immunity that requires a deep understanding of the molecular mechanisms involved in plant defense activation. Plant immune responses are triggered through the perception of conserved microbe-associated molecular patterns (MAMPs) which are recognized by pattern recognition receptors (PRRs) at the plasma membrane.

Can soil nitrate explain polyphenol and anthocyanin content in vineyard with similar available soil water regime?

Nitrogen (N) is quite important nutrient in grapevine development and must quality, but under Mediterranean climatic conditions, available soil water (ASW) during grapevine development can also influence vigour and must quality. The aim was to determine the influence of soil nitrate (NO3-) availability on N foliar, yield, and must quality in vineyards with similar available water holding capacity (AWC). For this purpose, four cv. Tempranillo (Vitis vinifera L.) vineyards were selected. All of them are placed in Uruñuela municipality (La Rioja, Spain), separated less than 2.5 km and in a slope <1 %, in soils with similar soil chemistry properties and with similar rooting depth (ranging between 105 cm and 110 cm).
