Effects of Ganoderma boninense infection on physiological responses of oil palm. Lignin content (a), peroxidase activity (b), and salicylic acid content (c) of oil palm seedlings at four months and seven months after planting (MAP). Note: For each observation parameter, the average of 4 months and 7 months after planting with the same lowercase letter shows that they were not significantly different based on a t test at α = 0.05. Similarly, the average value of each accession with the same lowercase letter shows that they were not significantly different based on the Tukeys's Honest Significant Difference (HSD) test at α = 0.05. The t test was conducted using StatPlus, while ANOVA and HSD used Statistical Tool for Agricultural Research (STAR) program
