Abstract:
The effect of 0, 10, 20, 30, 40 and 50 ppm aluminium on the yield
and growth characters of the rice plant grown in solution culture was studied,
Toxicity symptoms of aluminium were not manifested on the tops while root
growth was progressively decreased in 20, 30, 40 and 50 ppm aluminium
containing pots. Decrease in root growth was associated with a tendency for
root branching and the formation of mere vascular traces in the root cortex.
The reduced root growth did not suppress the yield.
