By using two durum wheat cultivars (Triticum durum L. cvs. Balcali-85 and C-1252) a nutrient solution experiment was carried out to study i) genotypic variation in cadmium (Cd) tolerance, ii) Cd concentrations in plants, and iii) the role of ascorbic acid and non-protein SH groups (SH: sulphydryl) in Cd tolerance. Plants were grown under controlled climatic conditions for 15 days and subjected to increasing Cd supply (0, 6, 30, 75 and 150 µM). Of the two cultivars, C-1252 showed greater sensitivity to Cd toxicity as judged from the severity of Cd toxicity symptoms on leaves. Increasing Cd supply markedly reduced …
