enzyme activity of ascorbate peroxidase (APX), for 2 varieties, Suakoko8 and IR31785, in samples of the leaf blade, the sheath of the youngest fully developed leaf of the main culm, the blade and sheath of the third youngest fully developed leaf of the main culm, and the root, samples are fresh or stored for 1-12 weeks frozen, or freeze-dried, overview | Oryza sativa |

effect of dfferent storage methods such as freeze-drying, freezing at -20°C, and freezing at -80°C on the activity of enzyme ascorbate peroxidase from two rice varieties, overview. When subjected to different storage methods, there are no differences between varieties, but strong effects of the different storage methods on enzyme activities are found strongly differing between extracts from stored tissue samples or extracts stored from freshly sampled material. Enzyme-specific storage methods and durations allow for expanding the window for analyses in large experimental studies involving destructive samplings for enzyme kinetics | Oryza sativa |
