This study evaluated the performance of Pinus patula Schl. et Cham. planted in two environments in Chignahuapan, Puebla, Mexico. The first environment was a low-density Pinus teocote Schl. & Cham. and P. patula stand. The second was the same stand after a prescribed low-intensity burn. Acclimatation of four height classes were tested one year after planting date, considering survival, growth in height and diameter, biomass and levels of foliar nitrogen and phosphorous. One year later (June 2001), survival of 92 and 94% for the burned and non-burned sites, respectively, was found. This variable was not affected by the factors treatment, height class, or their interaction. The small and middle size plants from both the burned and non-burned areas had the highest relative height growth rate, and the small plants in non-burned areas had the largest height increment. The largest plant in the non-burned area had the highest relative diameter growth rate, and also the highest lateral root biomass. Foliar nitrogen was lower in the burned sites, probably due to volatilization. No effects were found for phosphorous.
