FIGURE 2.

Leaf reflectance of specific wavelengths in susceptible cultivar 23, 31, 36, and 51 DAP in addition to the reflectance of the resistant cultivar 36 DAP. (A) Average reflectance in the far-NIR (800–1300 nm) and (B) SWIR (1450 nm range). O. cumana attachments first observed at 31 DAP. There were eight replicates for each treatment. Bars refer to SE of the mean and asterisks indicate significant differences between treatments (0.05 ≥ α).
