(A) Impact of exogenous supplementation of phytohormones (Indole acetic acid; IAA and Kinetin; KN) on nitrate and nitrite uptake rate of Nostoc muscorum and Anabaena sp. exposed to CrVI stress for 96 h. Data are means±standard error of three replicates (n = 3). Bars followed by different letters show significant difference at P < 0.05 according to Duncan multiple range test (DMRT). (B) Impact of exogenous supplementation of phytohormones (Indole acetic acid; IAA and Kinetin; KN) on nitrate and nitrite reductase activities of Nostoc muscorum and Anabaena sp. exposed to CrVI stress for 96 h. Data are means±standard error of three replicates (n = 3). Bars followed by different letters show significant difference at P < 0.05 according to Duncan multiple range test (DMRT)
