Allocation of nutrients in huckleberries
1989
Stark, N. | Baker, S. | Essig, D.
Plant nutrient content and major organic components were determined in 35 clones of huckleberry (Vaccinium globulare Rydb.) growing in seven major berry-producing areas of western Montana. Roots were sinks for Al, Cu, and Fe, while leaves concentrated B, Mg, and Si. Flowers were high in K, P, Zn, and total N. Berries had a high Na content. Leaves of young plants contained different nutrient concentrations than those of older plants without berries. Mature plants that produced berries differed in nutrient concentrations from those that did not. Productivity of wild plants under moderate climatic stress can be predicted using the concentrations of Ca and Mg in the old stems, Cu and calories in the rhizomes, Fe in the new stems, and from the total plant ash content. Large high-producing plants had significantly greater concentrations of nearly all nutrients than large low-producing plants. Plant size and age appear to be related to berry production, which was highest in soils with high organic content and high available elemental content.
