Species Info

  • Guazuma crinita


  • This research addresses the intra-specific variation in the native Peruvian tree species Guazuma crinita, a fast-growing pioneer species and priority timber tree used in reforestation and agroforestry systems.
  • This paper evaluates the tree growth and wood density of G. crinita varieties from 11 provenances in the Peruvian Amazon.
  • Trees from the different provenances were planted in the lower, middle, and upper parts of the watershed in which soil fertility and mean annual precipitation increase from the lower to upper parts of the watershed.
  • Tree height and stem diameter were measured at 6, 12, 18, and 30 months and wood density was evaluated at 32 months.
  • There was little variation in the density of the trees, but in general larger trees had lower density.
  • There was much more variation in tree growth. When considered independently by planting site, the provenance closest to the test site performed better than the other provenances.
  • Together, the authors found that the effect of the planting site on growth and density was much higher than the effect of provenance.
  • Tree growth was lower in the lower planting zone with higher variation in the growth by provenance, suggesting that provenance may play a larger role in less favorable site conditions.
