| performance of several models for predicting budburst date of grapevine (vitis vinifera l.). | the budburst stage is a key phenological stage for grapevine (vitis vinifera l.), with large site and cultivar variability. the objective of the present work was to provide a reliable agro-meteorological model for simulating grapevine budburst occurrence all over france. the study was conducted using data from ten cultivars of grapevine (cabernet sauvignon, chasselas, chardonnay, grenache, merlot, pinot noir, riesling, sauvignon, syrah, ugni blanc) and five locations (bordeaux, colmar, angers, m ... | 2009 | 19280231 |
| study of the phenotypic and genotypic biodiversity of potentially ochratoxigenic black aspergilli isolated from grapes. | ochratoxin a (ota) is a mycotoxin with nephrotoxic, carcinogenic, teratogenic and immunotoxic effects, naturally found in agricultural products including grapes and wine. black aspergillus species (section nigri) are mainly responsible for ota accumulation in wine grapes and in particular aspergillus carbonarius and aspergillus niger aggregate. the biodiversity of potentially ochratoxigenic strains of black aspergilli from different french vineyards in the southern mediterranean region of langue ... | 2009 | 19386377 |
| effect of irrigation and timing and type of nitrogen application on the biochemical composition of vitis vinifera l. cv. chardonnay and syrah grapeberries. | this study reports the effect of different doses of nitrogen applied to soil and/or leaves of syrah and chardonnay grapevines in the languedoc-roussillon (france) over two years. in 2011, nitrogen treatment involved both foliar urea sprayings and soil application at two different levels, with two controls - irrigated without nitrogen and no irrigation nor nitrogen. in 2012, the same grapevines received either soil or foliar nitrogen using the same controls. results showed that foliar application ... | 2018 | 28958516 |
