dendroides, whose signal given by the immunocytochemical detection was
similar to that in vascular plants. However, it was reported that phloroglucinol
(Wiesner reagent) staining, commonly used to detect lignin, was negative in
Sphagnum novozelandicum (
Kremer et al., 2004
). A similar outcome was
described by
Ligrone et al.(2008)
, where the phloroglucinol test was negative
