【 摘 要 】

The foliar concentrations of the macronutrients Mg, Ca, K, N, and P and the micronutrients Fe, Mn, B, Cu, Mo, and Zn were measured in field grown Pinus canariensis trees. Plots were chosen all over the range of this species in Tenerife to establish a survey of the nutrient concentrations. Compared to available data from related pine species (P. halepensis, P. pinaster, P. radiata) P. canariensis needles had lower N and P concentrations, higher Ca and Mg, and about equal K concentrations. N/nutrient ratios were in the range considered optimal for pine species. Micronutrients were in the range considered adequate for pines except for low Cu values. (C) 2003 Elsevier B.V.
