Hydrogen peroxide (H 2 O 2 ) content and catalase activity were studied in pea ( Pisum sativum L.) seedlings with a normal (cultivar Marat) and disrupted (pea mutants) process of nodulation that were inoculated with the nitrogen-fixing bacterium Rhizobium leguminosarum strain CIAM 1026. ...
The involvement of hydrogen peroxide (H_20_2) metabolism and catalase activity in dormancy release and sprouting of potato (Solarium tuberosum L.) tubers has been investigated in nine cultivars with a contrasting dormancy length. Phenotypic characterisation of tubers dormancy was established for all ...
IN a recent letter1 Johnson and van Schouwenburg dispute Keilin and Hartree's observation2 that catalase activity depends on the presence of oxygen. In their reply, Keilin and Hartree3 point out that the experiments of Johnson and van Schouwenburg are only qualitative and therefore not ...
