The values represent the average counts ± standard error of the mean (SEM). Numbers that have different letters in the same column (A,B,C) indicate statistical significant (P ≤ 0.05) between treatments within Plant B at each time point. Numbers in the same column that are not followed by letters indicate no significance found.
