Colour and chemical composition of fruits of 10 red raspberry genotypes grown in Nordic climate during three harvest seasons were studied. The main phenolic compounds in the fruits were ellagitannins and anthocyanins, contributing 57% and 42% to the quantified phenolic compounds, respectively. Cyanidin-3-sophoroside was the most abundant anthocyanin (61%). All quality parameters were significantly affected by genotype. The genotypes could be categorised into three groups. 'Veten' and 'RU984 06038' were characterised by high concentrations of flavonoids, i.e., anthocyanins and quercetin glycosides, and dark red colour. 'Octavia', 'Glen Magna', 'RU004 03067', 'Glen Ample' and 'RU974 07002' were characterised by light colour, high titratable acids and low flavonoid concentrations. 'Malling Hestia', 'RU024 01003' and 'RU004 04095' had high content of dry matter, soluble solids, ascorbic acid and ellagic acid containing compounds, in addition to high hue and chroma values. All quality parameters, except ascorbic acid and lambertianin C, varied significantly between harvest seasons. The lowest seasonal variation in fruit quality was observed in 'RU024 01003' and 'Glen Ample' and the highest 'RU004 03067' and 'Glen Magna'.
研究了 10 种红树莓品种在北欧气候下三个收获季节的果实颜色和化学成分。果实中的主要酚类化合物为鞣花单宁和花青素，分别占定量酚类化合物的 57%和 42%。矢车菊-3-槐糖苷是最丰富的花青素（61%）。所有质量参数均受基因型显著影响。可将基因型分为三组。'Veten'和'RU984 06038'的特点是类黄酮（即花青素和槲皮苷）和矢车菊素糖苷浓度高，颜色呈深紫红色。'Octavia'、'Glen Magna'、'RU004 03067'、'Glen Ample'和'RU974 07002'的特点是颜色浅、可滴定酸含量高、类黄酮浓度低。'Malling Hestia'、'RU024 01003'和'RU004 04095'的干物质、可溶性固形物、抗坏血酸和鞣花酸含量高，此外色调和色饱和度值也高。除抗坏血酸和 Lambertianin C 外，所有质量参数在收获季节之间均有显著差异。在 'RU024 01003'和'Glen Ample'中观察到果实品质的季节性变化最小，而在 'RU004 03067'和'Glen Magna'中观察到的季节性变化最大。
