Root parameters and main and interactive effects of zinc and SaMR12 on root tips, root total length, and root surface area of S. alfredii.

Values represent the mean ± standard deviation of three replicates.*Significant at the P**Significant at the PThe different letters following the values in the same column indicate significant differences between the treatments at PSaMR12 on the root tips, root total length and root surface area of S. alfredii were examined by two-way analysis of variance. Both SaMR12 and zinc treatment significantly affected root tips (F = 199.2, PF = 47.6, PF = 140.3, PS. alfredii (PS × Zn) at the PThe surface areas did not include root hairs which cannot be detected using the root automatic scan apparatus.Root parameters and main and interactive effects of zinc and SaMR12 on root tips, root total length, and root surface area of S. alfredii.
