TableĀ 1 Average Bruker score against triplicate reference spectra from seeds collected in 2017 for 12 blind-test seeds also collected in 2017 from Harmondsworth Moor, Lampeter, Rhosmaen, and Silwood Park (three seeds from each site)

From: Discrimination between regional biotypes of Impatiens glandulifera using a simple MALDI-TOF MS-based method for use with seeds
