Boron has been described as essential micronutrient for the development of some plants, including the vine. The objective of this study was to determine whether different applications of boron directly to bunches had any effect on vineyard productivity, chemical composition and on grape physical properties. The results obtained after two years trial indicated that boron sprays increased the productive parameters of the vineyard. Application of boron directly to the grape bunches proved to be effective in the absorption of this micronutrient by the vine, increasing the boron content in the grapes treated with different concentrations. In addition, boron-treated grapes have a higher concentration of organic acids and better cell wall definition than control sample grapes. The exogenous application of this micronutrient, as a complement to agricultural treatments, can be an interesting strategy to increase vine productivity and grape quality.

硼已被描述为某些植物（包括葡萄藤）发育的必需微量营养素。本研究的目的是确定硼直接应用于葡萄串是否对葡萄园生产力、化学成分和葡萄物理特性有任何影响。两年试验后获得的结果表明，喷硼提高了葡萄园的生产参数。事实证明，将硼直接施用于葡萄串可以有效地促进葡萄藤吸收这种微量营养素，从而增加用不同浓度处理的葡萄中的硼含量。 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 此外，与对照样品葡萄相比，硼处理的葡萄具有更高浓度的有机酸和更好的细胞壁清晰度。这种微量营养素的外源性应用，
