Fertilization with Seaweed (Laminaria japonica) on the characteristics of the bunch and the quality of the grape must of ‘Cabernet Sauvignon’

Abstract

The objective of the present work was to study the influence of the foliar application of seaweed (Laminaria japonica), on the bunch and on the must in the ‘Cabernet Sauvignon’ grape. The experiment was carried out in the years 2021/2022, in a 21-year-old commercial vineyard, in the municipality of “Dom Pedrito” – “Rio Grande do Sul” (RS). A completely randomized experimental design was used, with 4 treatments and 4 replications (7 plants per replication). The treatments were: T1- control treatment; T2- Exal Powder 5 g L-1; T3- Hidro Exal 15 ml L-1; T4- Exal Powder 5 g L-1+ Hidro Exal 15 ml L-1. Six applications were performed (every 15 days). The following were evaluated in the bunch: length (cm), width (cm), weight (g) and number of berries. Using the WineScanTM SO2 equipment (FOSS®, Denmark), the following were evaluated in the must: sugars (g L-1), pH, tartaric acid (g L-1), malic acid (g L-1), gluconic acid (g L-1), ammonia (mg L-1), potassium content (mg L-1). For all treatments and all variables analyzed, no statistical difference was obtained. It is preliminarily concluded that the application of foliar fertilizer based on seaweed (Laminaria japonica) did not influence the analyzed characteristics of the bunch and must of the ‘Cabernet Sauvignon’ vines.

New varieties descendant from Monastrell with lower sugar and high phenolic content adapted to warm climates

Given that climate change is a continuous process, it is necessary to constantly search for new strategies that help the viticulturist sector to mitigate its consequences. All adaptation strategies will have a greater or lesser effect that in turn will be marked by the times of action. As a long-term action, a genetic breeding program to obtain new varieties descendant from Monastrell has been developed in the Region of Murcia (more specifically, in the IMIDA Research Center) since 1997. In this program, new red varieties have been developed through directed crosses of the Monastrell variety with other varieties such as Cabernet Sauvignon, Tempranillo and Syrah.
