Appendix B. Scatterplots of glucosinolate concentration per area (mmol/m²) against tissue value and nitrogen per area.

FIG. B1. Greenhouse experiment scatterplots of glucosinolate concentration per area (mmol/m2) on (A) tissue value (% reduction in growth) and (B) nitrogen per area (g/m2). Data consist of the canopy fraction means for each trait. Statistics are shown for least squares regression. Upper (light gray), middle (dark gray), and lower fractions (black) are indicated as in Appendix A.
