Abstract:
A greenhouse experiment was conducted to establish the optimal fertilization management for Leucadendron 'Safari Sunset' (Leucadendron salignum x L. laureolum). Addition of NPK and micronutrient fertilizer or raising phosphorus concentration by itself increased total fresh weight and improved plant growth. Elevating the total nutrients or P concentration increased N and P concentrations. Clusters of proteoid roots were present along the root system of plants irrigated with tap-water, whereas few proteoid roots developed on plants irrigated with complete nutrient solution when only P was omitted, and none developed in any of the other treatments with P present. The pH in leachate of plants irrigated with tap water or with high nutrient levels (100, 20 and 100 mg L-1 of N, P and K, respectively) was consistently lower compared with leachate without plants. Increasing concentration resulted in a significant change in the ΔpH values (pH in leachate with plant - pH in leachate without plant) from negative to positive. This phenomenon is probably related to rhizosphere effects due to plant and microbial activity.
