TL;DR: Active oxygen species, which occurs during seed desiccation, germination and ageing, may lead to oxidative stress and cellular damage, resulting in seed deterioration, but cells are endowed with detoxifying enzymes and antioxidant compounds that scavenge AOS and participate in seed survival.

TL;DR: Explicit numerical methods for spatial derivation, filtering, and time integration are proposed in this article with the aim of computing flow and noise with high accuracy and fidelity, and they are constructed in the same way by minimizing the dispersion and the dissipation errors in the wavenumber space up to kΔx = π/2 corresponding to four points per wavelength.

TL;DR: The concept of the "oxidative window for germination" as mentioned in this paper restricts the occurrence of the cellular events associated with germination to a critical range of reactive oxygen species (ROS) level, enclosed by lower and higher limits.

TL;DR: The results obtained suggest that sunflower seed deterioration during accelerated aging is closely related to a decrease in the activities of detoxifying enzymes and to lipid peroxidation.

TL;DR: In this paper, the role of reactive oxygen species (ROS) in after-ripening of sunflower seeds was investigated at the cellular level by electron microscopy, concomitantly with lipid peroxidation and oxidation of specific embryo proteins.
