在澳大利亚一项关于气候变化对酿酒葡萄产量影响的研究表明,CO_2含量增加会造成酿酒葡萄早熟。为了研究气候变化是如何影响葡萄产量和品种的,研究人员将维多利亚西北部的葡萄树暴露在预测的2050年气温和CO_2浓度中。科学家Rachel Kilmister表示,气温升高2℃、CO_2浓度提高0.02%,葡萄生长及葡萄酒风味会受到显著影响。她说:“气温升高会造成葡萄早熟,收获期会提前;气温升高还会导致葡萄品质下降,红葡萄酒中呈色化合物和风味物质都会减少。到目前为止我们发现,CO_2增加会增强葡萄的光合作用,合成更多的碳水化合物。”
A study in Australia on the impact of climate change on the production of wine grapes showed that the increase in CO 2 content will cause premature ripening of wine grapes. To study how climate change affects grape yields and varieties, the researchers exposed the vines in northwestern Victoria to the projected 2050 temperatures and CO 2 concentrations. Rachel Kilmister, a scientist, said that a 2 ° C rise in temperature and a 0.02% increase in CO 2 levels could significantly affect grape growth and wine flavor. She said: “Higher temperatures will cause premature grapes and lead to earlier harvesting periods; higher temperatures will result in lower quality grapes and less colored compounds and flavors in red wines. So far we have found that CO 2 increases Photosynthesis of grapes, the synthesis of more carbohydrates. ”
