Vol. 36, No. 5, September/October 1993, p. 1383-1386.# of Pages: 4 Publishing Information: St. Joseph, MI Keywords: TIC Keywords: Festuca arundinacea ; Lolium perenne ; Seed mixtures ; Seed harvesting ; Seeds Abstract/Contents: "Samples from two mixed lots of tall fescue (Festuca arundinacea ) and ryegrass (Lolium perenne ) seed were hand separated and 10 physical properties of the individual seeds of both species were measured or calculated using a machine vision system (MVS). Data from measurements were subjected to logistic regression analysis, and models were created to distinguish the two species. A model created from the combined data from both lots characterized 83.13% of the tall fescue and 79.87% of the ryegrass. The combined regression model from both lots was then incorporated into a MVS algorithim, and previously unseparated quantities from each lot were separated based on the model. Using this procedure, an average of 83.87% of the tall fescue and 72.64% of the ryegrass seed were correctly classified. This procedure demonstrates potential for future automated MVS purity analysis and separation of mixtures of tall fescue and ryegrass and other difficult-to-separate seed lots."
