Fig. 1. Linear regressions of shoot and root mass on post-emergence time for reed canarygrass cultivars and various populations selected for improved establishment capacity: (A) shoot mass of five cultivars and five selected populations, (B) shoot mass of three composite populations representing increasing selection intensities (WR00 > WR99 > WR97), (C) root mass of five cultivars and five selected populations, and (D) root mass of three composite populations.
