The development and ripening process of sweet cherry (Prunus avium L. cv. 4-70) on the tree was evaluated. For this purpose, 14 different stages were selected in accordance with homogeneous size and color. Some parameters related to fruit quality, such as color, texture, sugars, organic acids, total antioxidant activity, total phenolic compounds, anthocyanins, and ascorbic acid were analyzed. The results revealed that in sweet cherry, the changes in skin color, glucose and fructose accumulation, and softening process are initiated at early developmental stages, coinciding with the fast increase in fruit size. Also, the decrease in color parameter a was correlated with the greatest accumulation of total anthocyanins. Ascorbic acid, total antioxidant activity (TAA), and total phenolic compounds decreased during the early stages of sweet cherry development but exponentially increased from stage 8, which coincided with the anthocyanin accumulation and fruit darkening. TAA showed positive correlations (r(2) = 0.99) with both ascorbic acid and total phenolic compounds and also with the anthocyanin concentration from stage 8. Taking into account the reduced shelf life of sweet cherry and to ensure that these fruits reach consumers with the maximum organoleptic, nutritional, and functional properties, it is advisable to harvest sweet cherries at stage 12 of ripening.
对甜樱桃(Prunus avium L. cv. 4 - 70)在树上的发育和成熟过程进行了评估。为此,根据果实大小和颜色均匀一致的标准选择了14个不同阶段。分析了一些与果实品质相关的参数,如颜色、质地、糖分、有机酸、总抗氧化活性、总酚类化合物、花青素和抗坏血酸。结果表明,在甜樱桃中,果皮颜色变化、葡萄糖和果糖积累以及软化过程在发育早期就开始了,这与果实大小的快速增加同时发生。此外,颜色参数a的降低与总花青素的最大积累相关。抗坏血酸、总抗氧化活性(TAA)和总酚类化合物在甜樱桃发育早期有所下降,但从第8阶段开始呈指数增加,这与花青素积累和果实变黑同时发生。从第8阶段开始,TAA与抗坏血酸、总酚类化合物以及花青素浓度均呈正相关(r(2) = 0.99)。考虑到甜樱桃的货架期较短,为确保这些果实以最佳的感官、营养和功能特性到达消费者手中,建议在成熟的第12阶段采收甜樱桃。
