摘要

本研究旨在确定不同水分约束条件下当地和知名酿酒葡萄2年生品种植物营养含量的变异。拥有8个有根盆栽葡萄品种(cv。在营养生长期间(5月至9月下旬),‘adakarasir’、‘papazkarasir’、‘Karasakız’、‘Karalahana’、‘Yapıncak’、‘Vasilaki’、‘赤霞珠’和‘长相思’连续两年进行5种灌溉处理(每日有效水量灌溉100%、每日有效水量灌溉75%、每日有效水量灌溉50%、每日有效水量灌溉25%、0%处理不灌溉)。叶片组织中氮、钾、镁含量随水分的减少而增加。磷和钙的含量也有类似的影响。叶片组织中硫含量基本保持不变。此外,遗传势的变异也影响了所研究品种的营养摄入量。葡萄品种应对缺水的能力必须在制定适应策略时进行评估,以使葡萄种植在气候危机的影响下可持续发展。

Influence of water scarcity on macronutrients contents in young leaves of wine grape cultivars
This study aimed to determine the variability of plant nutrition content in two-year old local and well-known wine grape cultivars under different water constraint scenarios. Own rooted and potted eight grapevine cultivars (cv. ‘Adakarası’, ‘Papazkarası’, ‘Karasakız’, ‘Karalahana’, ‘Yapıncak’, ‘Vasilaki’, ‘Cabernet Sauvignon’ and ‘Sauvignon Blanc’) were subjected to five irrigation treatments (100% daily irrigation of available water capacity (AWC), 75% irrigation of AWC, 50% irrigation of AWC, 25% irrigation of AWC, and no irrigation for 0% treatment) for two consecutive years during vegetative growth (May – late September). An increase in nitrogen, potassium and magnesium contents in leaf tissues with decreasing water amount was observed. Similar effect was found for phosphorus and calcium contents. The sulfur concentration in leaf tissues remained almost unchanged. In addition, the variability of genetic potential influenced the nutrient intake of the studied cultivars. The ability of grapevine cultivars to cope with the water deficit of the cultivars should definitely be assessed in adaptation strategies developed to make viticulture sustainable under the effects of the climate crisis.
