In laboratory conditions were tested some winter wheat varieties (registered in the Slovak Republic) for tolerance to low pH and Al3+ ions in juvenile stage. Experimental plants were cultivated 10 days in air-conditioned chamber in two culture media - in naturally acid soil (pH 4) and in acid nutrient solution with content of 10 ppm Al3+ (pH 4 + Al3+). As standard varieties, the Rumanian tolerant variety Albota and American sensitive variety Scout - 66 were used. The results have shown that these varieties are very suitable for testing of winter wheat varieties for tolerance to low pH and Al3+. From Slovak varieties the most tolerant variety was Rada and the most sensitive Solida. Other varieties rank among medium sensitive and medium tolerant, respectively. Positive correlation between the studied traits suggest that length and weight of roots and leaves can be used equally in testing winter wheat varieties for low pH and Al3+ ions tolerance. Positive correlations between culture media have shown that both media can be used comparably for cultivation and testing for the studied stresses
