摘要

2014-2015年,我们在mini - maderat葡萄园对费特丝卡尼格拉、赤霞珠、黑皮诺、梅洛、勃艮第和卡达卡等红葡萄品种进行了调查。通过研究,建立了作物负荷、叶面积与葡萄品质(糖含量、可滴定酸度、糖酸指数和花青素)之间的相关性和数学模型。最佳作物负荷因品种而异,取决于每种作物。研究了4种作物负荷(20、30、40和50芽/株)对产量和葡萄品质的影响。生产质量是一个指标,可以通过适当的修剪来优化。从这个角度来看,费蒂斯卡尼格拉和梅洛品种表现最好,而勃艮第和卡达尔卡在实验变种之间的质量差异较小。相关性和数学方法因品种而异;在不同的作物负荷下记录优良的品质指标,并通过统计和数学方法和解释精确确定。虽然修剪是一个广泛研究的技术阶段,但可以根据生产目的地,环境条件和葡萄园管理对每个品种进行优化。统计分析表明,赤霞珠品种在葡萄质量参数方面表现最好,而勃艮第和梅洛品种在两个试验年份的结果都很好。本研究旨在探讨作物负荷对葡萄品质、产量和光合效率的影响。

Research Concerning the Correlation between Crop Load, Leaf Area and Grape Yield in Few Grapevine Varieties

Several red grapevine varieties like Feteasca neagra, Cabernet Sauvignon, Pinot noir, Merlot, Burgund and Cadarca were investigated during 2014-2015 in the vineyard Minis-Maderat. Following research, correlations and mathematical models were made differentiated between crop load, leaf area and grapes quality (sugar content, titratable acidity, sugar-acidity index and anthocyanins). Optimal crop load varies from one variety to another, depending on each of them. The effect of four crop load (20, 30, 40 and 50 buds/vine) was study for their influence on yield and grape quality. The quality of production is an indicator that can be best optimized by proper pruning. From this point of view, Feteasca neagra and Merlot varieties had the best behaviour, while the Burgund and Cadarca recorded smaller qualitative differences between experimental variants. Correlations and mathematical methods vary from one variety to another; superior quality indices were recorded at different crop load, determined with precision by statistical and mathematical methods and interpretation. Although pruning is a technological stage extensively studied, it can be optimized for each variety according to the production destination, environmental conditions and vineyard management. Statistical analysis showed that the Cabernet Sauvignon variety perform the best concerning the grape quality parameters while Burgund and Merlot are varieties with week results in both experimental years. The aim of the study was to investigate the influence of crop load on grape quality, grape yield and photosynthetic efficiency.
