Fig. 1. (A) Changes in ergovaline concentrations (near-infrared reflectance [NIR] predicted) of grazed (October defoliation only) and stockpiled Jesup with the wild-type endophyte for canopy (SE = 35.6 µg kg^–1) and for the leaf (SE = 22.1 µg kg^–1), stem (SE = 126.2 µg kg^–1), and dead (SE = 10.4 µg kg^–1) fractions, and (B) the proportion of the tall fescue mass that is leaf (SE = 6.1%), stem (SE = 2.3%), and dead (SE = 6.9%) tissue (mean of three replicates and 3 yr).
