Abstract
The current water scarcity forces farmers to adopt new irrigation strategies to save water without jeopardizing the fruit yield and quality. In this study, the influence of 3 regulated deficit irrigation (RDI) treatments and 3 rootstocks on the functional quality of pistachios were studied. The functional parameters studied included, polyphenols, triterpenoids, and inhibition of α-amylase. The results showed that P. terebinthus and P. atlantica rootstocks led to pistachio kernels with higher contents of polyphenols and triterpenoids (mainly betulinic acid with 111 and 102â¯Âµgâ¯gâ1, respectively) than pistachios obtained using P. integerrima rootstock (81â¯Âµgâ¯gâ1). On the other hand, the use of moderate RDI (T1 treatment) increased the total content of polyphenols (â¼10%), quercetin-O-galloyl-hexoside (â¼15%), keampferol-3-O-glucoside (â¼19%), and polymeric procyanidins (â¼20%), as compared to the control trees, resulting in pistachios with a better functional profile, lower economic cost and with a lesser environmental impact.
