Fig. 4. Nonlinear regressions of concentrations of lignin on time in storage for bermudagrass hay baled at moisture concentrations of 302 [high moisture (HM); solid bold line, squares], 265 [medium moisture (MM); dashed line, diamonds], and 219 [low moisture (LM); solid light line, circles] g kg^-1. Regression equations for HM [Y = 65.4 - 16.8e^-0.038t²; r² = 0.90; root mean square error (RMSE) = 3.0], MM (Y = 58.1 - 12.6e^-0.032t²; r² = 0.83; RMSE = 3.1), and LM (Y = 62.1 - 14.5e^-0.010t²; r² = 0.86; RMSE = 3.2).
