Abstract

ABSTRACT: Recalcitrant and intermediate seeds have limitations regarding conservation because of their sensitivity to desiccation and response to storage. Establishing a method for seed storage is difficult because these seeds deteriorate rapidly, which can intensify production of reactive oxygen species that cause lethal oxidative damage to plant tissues. Orthodox seeds, which have greater tolerance to desiccation and storage, are also subject to deterioration processes, in degrees that vary according to the species. Damage caused by harmful levels of free radicals can be mitigated by the action of endogenous or exogenous antioxidants. Recent studies have led to new technologies for protection coming from antioxidants, one of which is cathodic protection. This is a technique with promising results in recalcitrant species, as well as in other living organisms. This paper reviews results regarding the antioxidant activity of cathodic water produced from electrolysis of a calcium chloride and magnesium chloride solution.

Highlights

Deterioration of seeds of all species during storage is associated with the loss and oxidation of antioxidant systems (DUSSERT et al, 2006), which may lead to generation of reactive oxygen species (ROS), free radicals, peroxidation of compounds, enzyme inactivation, and loss of viability (BENSON& BREMNER, 2004; ROACH et al, 2008; WHITAKER et al, 2010; BERJAK et al, 2011).Reactive species are chemical compounds, most of which have high reactivity

The authors examined the effectiveness of known chemical antioxidants and new means of cathodic protection (PAMMENTER et al, 1974; BERJAK et al, 2011) in the aqueous and dry phase in each step of cryopreservation so as to avoid the destructive effects caused by reactive oxygen species during the cryogenic process
