Plant domestication is an evolutionary process guided by human groups who modify the landscape for their needs. The objective of this study was to evaluate the phenotypic variations between populations of Spondias tuberosa Arruda (umbuzeiro) when subjected to different local landscape management strategies. The influence of the landscape management system on these populations was evaluated in five identified regional units (mountains, base of mountains, pastures, cultivated areas and home gardens). Ten individuals were randomly selected from each region and subjected to morphological and chemical fruit analysis. The diversity index, based on Simpson's index, was determined for the different populations. We then evaluated the morphological differences between the individual fruits from the distinct landscape areas. We observed no significant differences in morphological diversity between the areas studied. Our data suggest that the umbuzeiro specimens in this region may be in the process of incipient domestication.
植物驯化是一个由人类群体指导的进化过程,他们会根据自己的需求来改变景观。本研究的目的是评估在不同的局部景观管理策略下,斯潘迪亚· tuberosa Arruda(umbuzeiro)种群之间的表型变异。通过在五个不同的区域单元(山区、山脚下、牧场、耕地和家庭花园)评估景观管理系统对这些种群的影响。从每个区域随机选择 10 株个体进行形态和化学果实分析。根据辛普森指数确定不同种群的多样性指数。然后我们评估了来自不同景观区域的个体果实之间的形态差异。我们没有观察到研究区域之间形态多样性有显著差异。我们的数据表明,该地区的 umbuzeiro 标本可能正处于初始驯化过程中。
