“…Furthermore, some researchers carried out comparison studies on the absorption and usage efficiency of nitrogen fertilizer applied to leaves and soil during veraison to determine the optimal fertilizer 32,60,61 . Since 2014, the Institute of Vine and Wine Science in Spain has carried out comprehensive studies using local cultivars (Tempranillo and Monastrell) and focusing on the effects of different foliar nitrogen fertilizer types on nitrogen and flavor components 45–47, 62–67 . Other researchers found that the effect of nitrogen supplementation after veraison was better than before veraison 68 .…”

“…Therefore, a small amount of leaf nitrogen supplement can promote the accumulation of nitrogen in the grape and meet the nitrogen needs for grape in a timely and efficient manner, establishing a foundation for the accumulation of nitrogen during the fermentation process. (ii) FNAV could promote the accumulation of certain phenolics such as anthocyanins, flavanols and stilbenes 46,47,67 . With regard to this, there are two possible reasons: (a) moderate nitrogen supply may increase phenylalanine content, which is the precursor of phenolic components 83 and thus contributes to the accumulation of these metabolites during veraison 84 and (b) during veraison, essential growth is focused on grape development, so supplemental nitrogen may lead to an increase in photosynthesis of grapevine and promote the storage of excess photosynthesis products (i.e.…”

“…Moreover, FNAV has the potential to promote the synthesis and metabolism of secondary metabolites in grape, including accumulation of phenolic 45,46 and aromatic compounds 47 and finally modify wine flavor. 47,48 Currently, low nitrogen addition into soil is a prevailing agricultural management method, so FNAV is an adaptable and promising viticulture method for nitrogen supply to improve the components of flavor and YAN in grape and to finally modify nitrogen storage and flow processes from grape and must to finished wine.…”

Nitrogen is involved in the winemaking process from grapevine growth to wine fermentation, and its precise utilization in vineyards can regulate grape and wine quality. Foliar nitrogen application during veraison (FNAV) could prevent nitrogen deficiency in grape and must in nitrogen‐deficient vineyards. Moreover, FNAV also could improve certain flavor components of grape and wine, but little attention has been paid to FNAV. Therefore, this paper mainly reviews the difficulties encountered in current applications of nitrogen in vineyards and wineries, and the advantages of FNAV over the addition of nitrogen in soil and wineries. And it discusses that FNAV can increase yeast‐assimilable nitrogen and phenolics, and scarcely affect volatile components of grape (must and wine), and points out the existing problems including the core issue and then puts forward future research directions. This information may indicate future directions for research, and provide a reference for viticulturists and winemakers on the precise application of nitrogen on grapevine and must to further improve grape and wine quality in nitrogen‐deficient vineyards. © 2020 Society of Chemical Industry

BACKGROUND The influence of foliar nitrogen fertilizer during veraison (FNFV) on anthocyanin accumulation and chromatic characteristics of ‘Cabernet Sauvignon’ grapes over two seasons was investigated. RESULTS Urea and phenylalanine fertilizers (TU and TP, respectively) and a control were sprayed three times at veraison. In 2018, TU displayed a significant enhancement in total individual anthocyanin content and a* and Cab* profiles. In 2019, FNAV significantly improved the content of total non‐acylated, acylated anthocyanin and total individual anthocyanin, and the profiles of L*, a* and Cab*, except a* in TU. The whole process from phenylalanine variation to anthocyanin accumulation in grape skins was analyzed. On the whole, after the first FNFV to harvest, the increase in phenylalanine metabolism, abscisic acid content, effects of PAL (Phenylalanine ammonia lyase), UFGT (UDP glucose‐flavonoid 3‐O‐glucosyltransferase) and transcript concentrations of VvPAL and VvUFGT involved in anthocyanin biosynthesis were also strong evidence explaining the increased anthocyanin and chromatic profiles in 2019. CONCLUSION Overall, FNFV for nitrogen‐deficient grapevines could significantly improve grape color, especially in the 2019 veraison with a proper climate. © 2021 Society of Chemical Industry.
