Abstract

Young rubber plants were cultivated in BOLLE JONES nutrient solution. A separate aluminum solution was prepared by dissolving a thin aluminum foil with HCl lN. From this stock solution the following concentrations were prepared; none, 5, 10, 15, 20 and 25ppm of aluminum. The plants remained for 24 hours in nutrient solution and for another 24 hours in the aluminum solutions. This procedure was carried out during 95 days. After 95 days the plants were harvested and divided into top whorl, 2nd and 3rd whorls, stem and roots. The material was dried and analysed for Fe, Mn and Zn. Concentration and accumulation of Fe and Mn was affected by 20ppm of aluminum in the solution. The concentration and accumulation of Zn in the roots and leaves was affected by 15ppm of aluminum in the solution.
