Aluminum Toxicity in Sweet Cherry Trees Grown in an Acidic Volcanic Soil

Chile is the world’s largest exporter of sweet cherries. New plantings have been shifted to southern regions, where aluminum (Al) phytotoxicity could be a serious constraint on establishing orchards in acidic volcanic soils. This study investigated effects soil Al growth and macronutrient uptake non-bearing ‘Bing’ Gisela®6 trees grown 120 L pots containing with four concentrations exchangeable (0.12, 0.40, 0.60, 1.24 cmol kg−1). At end first second seasons after planting, were destructively harvested, individual organs analyzed for dry weight, concentration, concentration. Increasing had detrimental effect nutrient growth, particularly season. However, fine-root was significantly reduced from season low concentrations. In cherry trees, preferentially accumulated root tissues its translocation aerial restricted. addition, accumulation fine roots, conjunction reduction severely restricted N, P, K, Mg, and, particularly, Ca. Therefore, acidity must corrected ensure successful establishment Chile.
