WebFeb 2, 2024 · The content of triphenyl tetrazolium formazan (TTF) produced by dehydrogenase per gram of seed in 1 h was used as seed vigor index. The α-amylase activity was tested by the 3,5-dinitrosalicylic acid method . For detection of α-amylase activity, enzyme extract was placed at 70 °C for 15 min to inactivate β-amylase before … Webtriphenyltetrazolium chloride (TTC) to triphenyl formazan (TPF). Each soil sample was treated with 0.2 ml toluene, 0.1 g of CaCO 3 and 1 ml of 0.18 mM aqueous solution of TTC and incubated for 24 h at 30°C. The TPF formed was extracted with methanol from the reaction mixture and assayed at 485 nm in a Spectronic-20D spectrophotometer. dennis lloyd never go back
