Abstract

Eleven Zea mays L. varieties were tested for acid phosphatase activities in excised roots treated with solutions containing 0, 10, 50, 100, 1 000 and 5 000 uM Al. The varieties Tuxpeno Caribe, Shaba I and Bandundu had the highest root acid phosphatase activities in Al treatments relative to the control. There was a correlation between root acid phosphatase levels under A1 stress and the differential A1 tolerance exhibited by Zea mays L. varieties in field trials.
