Figure 3. Relationship of blue-based wide dynamic range vegetation indices (WDRVIs) at ‘’ levels of 0.1, 0.05, and 0.01 to leaf area index (LAI), mass shoot^–1, and shoot length. At each of the final four harvests in 2005, 20 LAI measurements and 40 mass shoot^–1 and shoot length observations were taken from each harvested plot.
