Abstract

Aluminum (Al) is a biotoxic metal to most of plants which inhibits root growth, led to a series of influence metabolic abnornal and becomes the main limiting factor productivity in acid soils. In this experiment, effect of Al strees on plant growth, root growth, macronutrient uptake (N, P, K, Ca, Mg) and Al uptake in root and plant were studied. Three pineapple crown of smooth cayenne clones (GP1, GP3 and F180) was cultured from 0 to16 weeks in aquadest culture medium that contain 6 level of Al concentration treatment 0, 100, 200, 300, 400 and 500 μM AlCl3. Experiments using a factorial randomized block design with 5 replications in a greenhouse growing environment. Results of this experiment showed that the three clones have a different response of tolerance to Al stress. GP3 clone showed the highest growth in the number of leaves, number of seminal roots, production of roots sugar, P leaf uptake and the lowest roots uptake of Al compared to other clones. GP1 clone produce the highest root length, percent of weight vertical root, and K leaf uptake. While F180 clone produces the highest water volume uptake of roots, weight of fresh roots, weight of plant, leaf uptake of N, Ca and Mg, and the lowest Al toxicity morphology than other clones. For the optimal balance proportion of plant and root growth, we can be said that F180 and GP3 clones have high levels to Al toxicity tolerance for that can growth well for acidic soils that have low pH.
