Dario Autovino | Tommaso La Mantia
This study examines the changes that have occurred in the specific and varietal composition of fruit trees in one of the world&rsquo:s most famous agricultural areas, the Conca d&rsquo:Oro, a plain surrounding Palermo (Sicily, Italy). Changes in specific and varietal composition over the centuries are the result of endogenous changes to the orchards (e.g., the spread of cultivation techniques such as irrigation or the introduction of new species and varieties), social and economic changes (e.g., the development of citrus farming in response to the demand from citrus markets). The disappearance of traditional germplasm is a complex phenomenon due to the changes occurring since the middle of the last century in the agricultural system. The more recent changes occur, unfortunately, mainly due to the expansion of the city, which has erased many orchards and vegetable gardens, but also due to the loss of the emotional, economic, and social value of orchards. The protection of this germplasm becomes indispensable in a period of climate change that, among other things, reduces the effectiveness of agrochemicals. Some germplasm protection and product enhancement initiatives are currently in place in this area and can be applied in other fruit-growing areas as well.
