Cultivar and Rootstock Effects on Growth, Yield and Nut Quality of Pistachio under Semi-Arid Conditions of South Mediterranean

Pistachio (Pistacia vera L.) cultivation under rainfed conditions of the South Mediterranean has not been studied in depth. Under changing climate conditions, knowledge cultivar and rootstock performances allows for optimal use genetic resources to improve yield nut quality. This study aimed evaluate growth, yield, fruit characteristics ‘Mateur’ ‘Achouri’ pistachio cultivars grafted on P. atlantica rootstocks grown northeastern Tunisia. The research was based three years worth monitoring Results showed that annual bio-climatic features had significant effects all parameters. higher vigor than ‘Achouri’. Fruit production but similar both Kernel fat contents (40.7–46.8%) fatty acid profiles were low or affected by cultivar, their combination. Oleic (C18:1) major (68.94–69.22%) kernel oil. unsaturated/saturated oleic/linoleic ratios indicated nuts obtained high lower may be related acclimation ability this cultivar. These however, seem suitable rootstocks.
