Results of two-way analysis of variance (ANOVA) assessing whether principal components (PC) of leaf reflectance data differentiate <i>Metrosideros polymorpha</i> that are <i>Resistant</i> and <i>Susceptible</i> to <i>Ceratocystis lukuohia</i> by artificial inoculation.

Data were alternately grouped by species variety (left) and site of mother tree origin (right), and groupings are indicated by bolded headings. Only PCs that were significant for either resistance or the interaction between resistance and site or variety are shown. Site locations and their abbreviations on Hawaiʻi Island are denoted as: Institute of Pacific Islands Forestry (IPIF), Keaukaha Military Reserve (KEMR) and Puʻu Kaliu (PUKA) in the district of Puna.
