Growth, Physiology and Nutrient Use Efficiency in Eugenia dysenterica DC under Varying Rates of Nitrogen and Phosphorus.

ABSTRACT: The production of high-quality seedlings and their use in commercial planting reduce pressure on natural areas. Eugenia dysenterica DC is a native fruit tree from the Brazilian Cerrado, whose nutritional requirements are still unclear. This study aimed to evaluate the effects of nitrogen (N) and phosphorus (P) supplementation on the physiology, growth and nutrient uptake, and use efficiencies of E. dysenterica seedlings grown in glasshouse conditions. The following rates were used in separate experiments: 0, 50, 100, 200, and 400 mg dm-3 N and 0, 100, 200, 400, and 600 mg dm-3 P. The experiment was conducted in a randomized block with four replications. The lowest N rate (50 mg dm-3) increased the stomatal conductance (gS) and, consequently, resulted in the highest transpiration (E), elect
