Fig. 2. The quadratic relationship between water-soluble carbohydrate (WSC) content (mg tiller–1; H4) and subsequent herbage yield (kg DM ha–1; H5) following defoliation to 20 (filled circle), 40 (open circle), 60 (filled triangle), 80 (open square), or 100 mm (filled square) residual stubble height over seven sequential harvests. Each data point indicates an individual replicate. The standard error was 412 kg DM ha–1.
