Means are from 12 seedlings (standard errors in parentheses) of each Hoheria, Aristotelia and Pseudopanax species. Each Melicope species had only six seedlings. Species within a genus (homo vs. hetero) followed by the same letter are not significantly different at the 5 % significance level. NA, data not available.
