About this episode
Giulia Marino discusses her research on how pollen sources affect polyphenol deposition in pistachios.
Giulia Marino and Pat J Brown (both UC Davis) have been examining another potential influence on polyphenol deposition in pistachio: whether the pollen source impacts deposition rates. In this episode, Giulia shares her results, as well as some other unexpected findings from pistachio xenia (the effect of the pollen source on the fruit).
