Title: Ponderosa pine progenies: differential response to ultramafic and granitic soils

Author: Jenkinson, James L.

Station ID: RP-PSW-101

Description: Progenies of nine ponderosa pines native to one granitic and several ultramafic soils in the northern Sierra Nevada were grown on both soil types in a greenhouse. The progenies differed markedly in first-year growth on infertile ultramafic soils, but not on a fertile granitic soil. Growth differences between progenies were primarily related to differences in calcium uptake from soils low in available calcium. On an extremely infertile ultramafic soil, progenies differed in survival. The results suggest that some ponderosa pines are better adapted than others to the nutritional conditions of ultramafic soil.

Key Words: Pinus ponderosa, genetic variation, progeny trials, nutrientuptake, serpentine soils, California
