Chlorate tolerance analysis of 12 wheat varieties during the seedling stage. (a) Shapes of the shoots of XM26 and LM23 after KClO₃ treatment for 20 h. (b,c) Phenotype of whole XM26 and LM23 plants under normal conditions (left) and KClO₃ treatment (right) for 4 d. (d,e) Plant heights and chlorate inhibition rates in different wheat varieties treated with 0 (normal) and 4 mmol/L KClO₃ for 4 d. * indicates a significant difference (p < 0.05) between different treatments. Lowercase letters indicate significant differences (p < 0.05) between different wheat varieties.
