Home gardens are considered germplasm repositories and places for experimentation, thus they are key sites for the domestication of plants. Domestication is considered a constant process that occurs along a continuum from wild to managed to domesticated populations. Management may lead to the modification of populations and in other cases to their distribution, changing population structure in a landscape. Our objective is focused on the management received in home gardens by perennial species of fruits. For this, the management practices applied to native and exotic perennial fruits species by a group of 20 women in the periurban zone of Iguazú, Argentina, were analyzed. In-depth interviews were conducted, as well as guided tours for the recognition and collection of specimens of species and ethnovarieties. Sixty-six fruit species managed in the home gardens were recorded. The predominant families are Rutaceae, Myrtaceae, and Rosaceae. The fruit species with the highest number of associated management practices are () and (). The 10 species with the highest management intensity are (in decreasing order of intensity) ( x ), (), (), (), (), (), (), ( x ), (), and (). Among the families with the greatest modifications in their distribution, abundance and presence of ethnovarieties in domestic gardens, are the native Myrtaceae and the exotic Rutaceae. The main management practices involved are cultivation, tolerance, transplant and enhancement in decreasing order. It can be concluded that in Iguazú, fruit species management shows both in plant germplasm as in environment a continuum that through tolerance, transplant and cultivation has derived in a mosaic of species in different management situations, which in turn are representative of an anthropogenic landscape in constant domestication and change.
家庭菜园被视为种质资源库和实验场所,因此它们是植物驯化的关键地点。驯化被认为是一个持续的过程,沿着从野生到管理再到驯化种群的连续统一体发生。管理可能导致种群的改变,在其他情况下还会导致其分布的变化,从而改变景观中的种群结构。我们的目标聚焦于阿根廷伊瓜苏城郊地区20名女性对多年生果树种类在家庭菜园中的管理。为此,分析了这组女性对本地和外来多年生果树种类所采用的管理措施。进行了深入访谈,并开展了有导游引导的参观活动,以识别和采集物种及地方品种的标本。记录了家庭菜园中管理的66种水果。主要的科为芸香科、桃金娘科和蔷薇科。相关管理措施数量最多的水果种类是()和()。管理强度最高的10个种类依次为(强度递减)(x)、()、()、()、()、()、()、(x)、()和()。在家庭菜园中分布、丰度和地方品种存在变化最大的科中,有本地的桃金娘科和外来的芸香科。主要涉及的管理措施依次为栽培、耐受、移植和改良。可以得出结论,在伊瓜苏,水果种类管理在植物种质和环境方面都呈现出一种连续统一体,通过耐受、移植和栽培,形成了不同管理状况下的物种镶嵌体,这反过来又代表了一个处于持续驯化和变化中的人为景观。
