Figure 2From: Contrasting nitrogen fertilization treatments impact xylem gene expression and secondary cell wall lignification in EucalyptusEffects of N fertilization on Eucalyptus urophylla × E. grandis xylem secondary cell walls. (a) Phloroglucinol-HCl staining of the basal stem sections from samples grown under N fertilization treatments (N-, N and N+). Bar = 100 μm. (b) SEM images from xylem secondary cell walls under limiting (N-) and luxuriant (N+) treatments.Back to article page
