Pteridium caudatum

Figure 16-A/B. Variation of low (LMP) and high (HMP) molecular weight phenolics with elevation in Pteridium caudatum (plot A) and P. arachnoideum (plot B) along elevation gradients in the northern Andes. Continuous lines are the calculated regressions for HMP only. Data from Alonso-Amelot et al., 2004)...

Fig. (1). Growth of pteridium aquilinum var caudatum fronds in a tropical mountain environment at 1850 m asl, from day of emergence above ground following fire. (A) variation in crozier density as a function of time. (B) elongation of blade central rachis. Accumulation of biomass may reach 5 g/d per frond each day at the maximum growth period. Data from Alonso-Amelot and Rodulfo, 1996, [18].
