Abstract

Breeding highbush blueberry (Vaccinium corymbosum L.) is a goal for many researchers, as many blueberry cultivars are cultivated worldwide mainly due to their biochemical composition that can reduce the risk of many diseases. The study was carried out over a period of three years to evaluate fruit size, average weight per fruit, firmness, but also the total content of bioactive compounds, such as polyphenols, flavonoids, anthocyanins, tannins and carotenoids, along with vitamin content. C, total sugar, extracted from frozen blueberries. Three blueberry cultivars ('Delicia', 'Northblue' and 'Duke'), an advanced selection ('4/6') and their hybrid progeny ('Delicia x Duke', 'Delicia x Northblue', ' Delicia x 4/6') were evaluated. The plants were grown at the Research Institute for Fruit Growing, Pitesti, Romania in open field studies in a randomized block with three replications (5 plants/genotype/replication). The research carried out showed the following: average weight/plant recorded values between 1.42 g (hybrid 16-12-10) and 2.47 g ('4/6'), fruit firmness showed variations from 13.9 N .('Northblue') to 29.37 N ('Delicia'), soluble dry matter 11.4°Brix (16-12-15) and 17.01°Brix (16-20-22), polyphenols oscillated from 114.98 (16-12-19) to 1,652 mg GAE/100g (16-20-12), vitamin C had a lower level of 2.3% and the upper level of 16.86% (16 - 9-10). These results indicate the importance of the blueberry species for its breeding and its role in health and nutrition.

关于一些蓝莓杂交后代果实生化成分的研究

培育高丛蓝莓（Vaccinium corymbosum L.）是许多研究人员的目标，因为全世界种植的许多蓝莓栽培品种主要是由于其生化成分可以降低许多疾病的风险。这项研究历时三年，不仅要评估果实大小、平均单果重量、坚硬度，还要评估生物活性化合物的总含量，如多酚、类黄酮、花青素、单宁和类胡萝卜素，以及维生素含量。C 是指从冷冻蓝莓中提取的总糖。对三个蓝莓栽培品种（"Delicia"、"Northblue "和 "Duke"）、一个高级选育品种（"4/6"）及其杂交后代（"Delicia x Duke"、"Delicia x Northblue"、"Delicia x 4/6"）进行了评估。这些植物在罗马尼亚皮特什蒂水果种植研究所的露地研究中生长，采用随机区组，三次重复（5 株/基因型/重复）。研究结果表明：平均单株重量介于 1.42 克（杂交种 16-12-10）和 2.47 克（'4/6'）之间，果实硬度从 13.9 N（'Northblue'）到 29.37 N（'Delicia'）不等。可溶性干物质为 11.4°Brix（16-12-15）和 17.01°Brix（16-20-22），多酚含量从 114.98（16-12-19）到 1,652 毫克 GAE/100克（16-20-12）不等，维生素 C 含量较低为 2.3%，较高为 16.86%（16-9-10）。这些结果表明了蓝莓品种对其育种的重要性及其在健康和营养方面的作用。
