(2016)The efficacy of two strains of Lanchancea thermotolerans in preventing the growth and ochratoxin A (OTA) accumulation of ochratoxigenic fungi under greenhouse and field conditions were evaluated during three consecutive ... -
Determination of alkaloids in onion nectar by micellar electrokinetic chromatography
(2016)Nectar is the most important floral reward offered by plants to insects. Minor components such as alkaloid compounds in nectar affect bee foraging, with great influence in seed production. CE is an advantageous tool for ... -
Combined effect of prefermentative cold soak and SO2 additions in Barbera D’Asti and Malbec wines : anthocyanin composition, chromatic and sensory properties
(2016)The effects of prefermentative cold soak (CS) combined with two SO2 additions (50 and 100 mg L1) on the anthocyanin composition, chromatic properties and sensory attributes of Barbera D'Asti and Malbec wines were studied. ... -
Malolactic fermentation induced by Lactobacillus plantarum in Malbec wines from Argentina
(2016)The current market requirements to obtain wines with enhanced complexity and varietal character propose the finding of new microorganisms capable of driving the malolactic fermentation (MLF) and contributing to new and ... -
Culture-dependent and independent techniques applied to monitor yeast species on cold soak at different temperatures in winemaking
(2016)Transformation of grape must into wine is a process that may vary according to the consumers' requirements. Application of cold soak prior to alcoholic fermentation is a common practice in cellars in order to enhance flavor ... -
Whole plant open chamber to measure gas exchange on herbaceous plant
(2016)Much of our understanding about CO2 and H2O gas exchange in plants has been gained from studies at leaf level. Extrapolation of results to whole plant is difficult and not always accurate. In order to overcome this limitation, ... -
Leaf carbohydrate metabolism in Malbec grapevines : combined effects of regulated déficit irrigation and crop load
(2016)Background and aims: Regulated deficit irrigation and crop load adjustment are viticultural practices used to improve grape and wine composition. Our objective was to evaluate the combined effect of irrigation and crop ... -
Potencial alelopático de lixiviados de cultivos de cobertura y malezas sobre plantas jóvenes de vid
(2016)Las interacciones entre la vid y especies herbáceas pueden involucrar competencia por recursos y alelopatía. Se presume que determinados cultivos de cobertura y malezas poseen efectos alelopáticos sobre el crecimiento de ... -
Efecto de la combinación Adara-M2624 y otros siete portainjertos sobre las características del dosel de dos variedades de cerezo
(2016)Se estudió la influencia de los portainjertos SL64, MxM60, MxM14, CAB6P, Weiroot 13, GiSeLa® 5 y GiSeLa® 6 y Adara-Mariana 2624, sobre el comportamiento vegetativo de las variedades de cerezo Bing y Celeste, durante 9 años ... -
