Antioxidant and chlorophyll dynamics differ between perennial flax (Linum perenne and Linum lewisii) and annual flax (Linum usitatissimum and Linum grandiflorum).

Abstract Among plants, there is considerable variation in maximum lifespan, with annual species living less than one year and perennial species living as long as 43 600 years. According to the Oxidative Stress Theory of Aging, the maximum lifespan of an organism is partly determined by the rate at which it accumulates oxidative damage to its biomolecules. Consequently, perennial species have likel…
