Abstract

Young rubber plants were cultivated in BOLLE-JONES (1957) nutrient solutions. A separate aluminum solution was prepared by dissolving a aluminum foil with HC1 N. From this stock solution the following concentrations were prepared - none, 5, 10, 15, 20 and 25 ppm of aluminum. Plants were grown alternately for periods of 24 hours in these aluminum solutions and in the Bolle-Jones solution. This procedure was conducted for 95 days after which period the plants were harvested and divided into top whorl, 2nd and 3rd basal whorls, stem and roots. The material was dried and analysed for Ca, Mg and S. The concentration and accumulation of these plant nutrients were affected by levels over 15ppm of aluminum in the solution.
