Agronomic performance of Blackberry cultivars in Lapa-PR

Abstract Phenological studies with blackberry cultivars and the physical, chemical and sensory characterization of fruits are necessary to select the best cultivar adapted to local conditions and for the correct destination of fruits. The objective of this work was to evaluate the phenological stages of different blackberry cultivars, as well as to determine the quality of fruits, focusing on the recommendation of cultivars that are more adapted to local climate conditions. Moreover, the aim was to indicate the best destination of fruits produced, for either fresh consumption or as raw material for processing. The results indicated that the cultivars studied have adequate conditions for the expression of their productive potential, being Tupy cultivar the most productive. Fruits of Tupy, Guarani and Cherokee cultivars presented dual aptitude, which means they can be consumed fresh or or as raw material for processing, whereas those of Xavante cultivar are suitable only for processing.

摘要 为筛选适配当地种植条件的最优黑莓品种，并明确果实的合理利用方向，开展黑莓品种物候学研究以及果实物理、化学与感官品质表征分析是十分必要的。本研究旨在评估不同黑莓品种的物候期，并测定果实品质，重点推荐更适配当地气候条件的品种。此外，本研究还旨在明确所产果实的最佳利用方向，即可鲜食亦可作为加工原料。研究结果表明，供试黑莓品种均具备发挥其生产潜力的适宜条件，其中‘图皮’（Tupy）品种的丰产性最优。‘图皮’（Tupy）、‘瓜拉尼’（Guarani）与‘切罗基’（Cherokee）品种的果实具备双重利用属性，即可鲜食亦可作为加工原料；而‘萨万特’（Xavante）品种的果实仅适用于加工用途。
