TLDR
The purpose of the review is to stimulate debate about the mechanism(s) of seed deterioration thereby improving understanding and directing future study of this important event that compromises seed and grain quality.Abstract:
Unpalatable food and unsatisfactory stand establishment are undesirable consequences of seed and grain deterioration. Considerable research has been generated in the last 15 years focusing on the physiology, repair, and assessment of seed deterioration, but this information has yet to be collated into a comprehensive review. The objective of this report is to systematically summarize these findings from a physiological perspective. A model of seed deterioration is forwarded arguing that free radical assault on mitochondrial membranes may be a primary event of seed deterioration. The purpose of the review is to stimulate debate about the mechanism(s) of seed deterioration thereby improving our understanding and directing future study of this important event that compromises seed and grain quality.read more

Active oxygen species and antioxidants in seed biology
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.

Seed treatments to overcome salt and drought stress during germination in sunflower (Helianthus annuus L.)
TL;DR: It was concluded that inhibition of germination at the same water potential of NaCl and PEG resulted from osmotic effect rather than salt toxicity, and hydropriming increased germination and seedling growth under salt and drought stresses.

From intracellular signaling networks to cell death: the dual role of reactive oxygen species in seed physiology.
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.

Vitamin E Is Essential for Seed Longevity and for Preventing Lipid Peroxidation during Germination
TL;DR: It is demonstrated that a primary function of tocopherols in plants is to limit nonenzymatic lipid oxidation during seed storage, germination, and early seedling development, and the vte mutant phenotypes explain the strong selection for retention of toCopherol biosynthesis during the evolution of seed-bearing plants.

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.
