Figure 6. Oxidative enzyme activities (mean ± SE) in soil samples collected under four different genotypes (SA = seed family from Alniphyllum fortune (A); SC = seed family from Cinnamomum camphora (C); SD = seed family from Daphniphyllum oldhamii (D) and SI = seed family from Idesia polycarpa (I)) and two genotypic diversity levels (Mo = mono-genotypic treatment; Mu = multi-genotypic treatment).

Different letters indicate significant differences (P < 0.05) between different genotypes or genotypic diversity levels according to split-plot ANOVA and LSD test (the latter only for different genotypes).
