ABSTRACT Prevention in the field of mycotoxin-producing fungi is the most effective strategy for controlling the presence of mycotoxins in foods. Chemical fungicides are widely used to protect crops, so their implications on mycotoxin production need to be considered. Therefore, the aim of this study was to evaluate the effect in vitro and on grapes of five fungicides commonly used on grape cultures in Brazil on Aspergillus carbonarius growth and ochratoxin A (OTA) production. At the doses recommended by manufacturers, most fungicides significantly reduced A. carbonarius growth and OTA product

Phenotypic characteristics of fruit particles, such as projection area, can reflect the growth status and physiological changes of grapes.

Résumé :

The article assesses the effect of gel fertilizers on growth (average shoot length and bush growth in general), grape productivity, quality and transportability. Studies on the effect of new generation mineral gel fertilizers on the table grape of the Italy variety in the Mountain Valley Crimea proved their positive impact on growth, yield and quality of grape plants. There was a significant increase in phytometric indicators in the experimental variant compared to the reference: the average length of one-year shoots – by 17.7 cm (9.9%) and growth of the bush – 153.6 cm3 (7.8%).

In this research, we propose a novel concept for a non-destructive evaluation of volatiles emitted from ripening grapes using solid-phase microextraction (SPME). This concept is novel to both the traditional vinifera grapes and the cold-hardy cultivars. Our sample models are cold-hardy varieties in the upper Midwest for which many of the basic multiyear grape flavor and wine style data is needed. Non-destructive sampling included a use of polyvinyl fluoride (PVF) chambers temporarily enclosing and concentrating volatiles emitted by a whole cluster of grapes on a vine and a modified 2 mL glass

AbstractThe Texas wine industry of the United States has experienced substantial growth in recent years and yet is constrained by a significant lack of supply of Texas grown grapes. Using a real options framework we examine the role that wine grape price uncertainty plays on the financial decision to invest in vineyard operations in the state of Texas. Given reasonable estimates of required rates of returns, investment and operating costs for typical Texas vineyards, it is found that grape price uncertainty results in a delay in investment and subsequently a lack of grape supply. This delay in

In 1988 and 1989 a muscadine vineyard at Tuskegee, Alabama was treated by post soil solarization (PSS) (covering of moist soil around muscadine plants with clear polyethylene plastic mulch to achieve high soil temperature) for 30 and 75 days, respectively. The average soil temperature in 1989 of 50 and 35 C at 5cm depth for solarized and bare soil, respectively during PSS. The results showed no visible detrimental effect on `Carlos' muscadine (Vitis rotundifolia) from the increased heating of the soil.

Gibberellic acid (GA3), a plant growth regulator used routinely in the production of seedless bunch grapes, was sprayed on the seeded muscadine grape cultivar Triumph. GA3 at 100, 200, and 300 mg·L-1 was sprayed on the leaves and fruit clusters at late bloom; a second spray followed 1 week later. The sprayed vines produced more than 20% seedless berries and the size of the berries with seeds increased significantly. GA3 application in commercial muscadine grape production may have potential benefits.

However, A. carbonarius was not detected in any sample. One of the samples was not contaminated by any mycotoxigenic species, and, therefore, it was selected for the isolation of potential biocontrol agents. In this context, Hanseniaspora uvarum U1
