Rare earth elements distribution in grape berries

Abstract

Rare Earth Elements (REEs) include 15 lanthanides, yttrium and scandium. Their occurrence in soil and plants seems to be closely tied to the geological composition of the underlying mother rock, to the physical and chemical properties of the soil and to the specific ability of the plant to take up and accumulate these microelements. To date knowledge regarding the composition and distribution of trace elements in Vitis vinifera has been lacking or is inadequate. The aim of this research was to study REEs distribution in Chardonnay berries harvested at ripeness in 2006 in Trentino (north-eastern Italy).
After washing and microwave acid digestion, both the total REEs content in the berries and the REEs distribution within the skin, seeds and flesh were quantified. Analysis of 13 elements (yttrium, Y; lanthanum, La; cerium, Ce; praseodymium, Pr; neodymium, Nd; samarium, Sm; europium, Eu; gadolinium, Gd; dysprosium, Dy; holmium, Ho; erbium Er; thulium, Tm; ytterbium, Yb) was carried out with an inductively coupled plasma mass spectrometer.
The total REEs content measured in berries was 2.079 μg/kg of fresh weight. The order in terms of percentage content within the berry was skin > flesh > seeds (p<0.05) for Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Ho and Er. For Tm and Yb there were no significant differences between the skin and flesh. Eu showed a significantly different distribution pattern.

Variety specific thresholds for plant-based indicators of vine nitrogen status

Aim: Several plant-based indicators of vine N status are reported in the literature. Among these, yeast assimilable nitrogen in grape must (YAN) and total N concentration of petiole and leaf blades are considered to be reliable indicators and so is the chlorophyll index, measured with a device called N-tester. The N-tester index is used to measure the intensity of the green colour of the leaf blade, and therefore to estimate its chlorophyll content.

Impact of oenological tannins on microvinifications affected by downy mildew

AIM: Vine diseases are still responsible for economic losses. Previous study in our laboratory, have shown effects of oenological tannins against Botrytis cinerea1,2. According to this, the aim was to evaluate the wine protection by oenological tannins against an another disease, the downy mildew. METHODS: During the 2020 vintage, infected grapes by downy mildew (Vitis vinifera cv. Merlot) were collected from the dispositive ResIntBio. The 100 kg were crushed, destemmed and dispatch into 10 aluminium tanks. SO2 was added at 3 g/hL. Oenological tannins (grape, quebracho, ellagitannin or gallotannin) were added at 100 g/hL into eight different tanks (4×2 tanks). The two last tanks were considered as control without addition of oenological tannins. Alcoholic fermentation was achieved with Actiflore 33® at 20 g/hL. Malolactic fermentation was achieved with Lactoenos B7at 1 g/hL. Finished wines were sulfited to obtain 45 mg/L of total SO2.
