摘要：This study aims to check the tolerance potential of Solanum tuberosum to accumulate fluoride (F). For this work S. tuberosum were grown for 87 days under five different concentrations of F viz. control, 11.05(T1), 22.11(T2), 44.21(T3), 110.53(T4) and 221.05(T5) mg per Kg NaF. Study results revealed that maximum reduction of root biomass (82.5 %) at the fluoride dose 95 mg NaF/Kg soil. However, growth ratio and tolerance index showed opposite trend with concentration of F. On the other hand, F accumulation pattern was recorded highest in leaves and % of total F translocation from soil to plant linearly decreases with increasing added fluoride in soil. The F accumulation in leaves, root, shoot and potato tuber is 3.96 mg NaF per Kg, 3.02 mg NaF per Kg, 2.8 mg NaF per Kg and 1.56 mg NaF per kg, respectively. It was inferred from this study that potato (S. tuberosum) accumulates fluoride at tissues level.
