Activated Charcoal Alleviates Fluoride Stress By Restricting Fluoride Uptake And Counteracting Oxidative Damages In The Rice Cultivar Mtu1010, Ankur Singh, Swarnavo Chakraborty, Aryadeep Roychoudhury

Turkish Journal of Botany

This work was aimed to explore the efficacy of activated charcoal (5 mg g^-1 soil) in abating fluoride (25 mg L^-1 NaF) stress in rice seedlings, since the protective role of charcoal is widely reported against other forms of abiotic stress. Application of NaF solution reduced germination rate, dry and fresh weight, and shoot and root length of seedlings. Extensive fluoride accumulation lowered the chlorophyll level along with higher electrolyte leakage and formation of H2 O2 , malondialdehyde, and methylglyoxal. Administration of activated charcoal lowered the extent of oxidative damages by inhibiting the uptake of fluoride ions. Exogenous …
