Effect of a biofertilizer on mycorrhizal infection and vegetal nutrition in a vineyard of Mendoza

Abstract

There are products that contain microorganisms and some are called biofertilizer. These microorganisms, when applied in the soil, can live associated with plants, favoring vegetal nutrition and plant health. The objective of this study was to evaluate the effect of the application of a biofertilizer in the mycorrhizal infection and vegetal nutrition in a Malbec vineyard in Mendoza. Under a completely randomized design, two treatments, (with biofertilizer (WB) and without biofertilizer (WOB)) were distributed with eight replicates and a dose 10 L.ha-1. Four applications were made, two during flowering and two after harvest for three years. During flowering, total N, P, K, Ca and Mg were determined in petioles, percentage of mycorrhization in root and number of spores of mycorrhizal fungi in soil. In addition, yield and pruning weight were determined too. The number of large spores was higher (671 spores.100 g-1soil) in WB soils after four applications. There was no effect on the percentage of mycorrhization (WB: 40.75 % and WOB: 29.4 %), nutritional levels (N-WB: 0.88 % and N-WOB: 0.84 %, P-WB: 0.38 % and y P-WOB: 0.35 %), yield (WB: 1.85 kg.plant-1 and WOB: 1.39 kg.plant-1). These results could be given by high amount of time needed for the efficient radical infection by fungi and subsequent increase in plant nutrition.

Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec

Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.

Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)

Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.

Phenological behavior and evolution of maturation of grapes of juice preparation

The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.
