Cytogenotoxicity potential of Syzygium aromaticum extract, an alternative treatment for Chenopodium quinoa seed
Abstract
Chenopodium quinoa Willd (quinoa) is a pseudo cereal that has been gaining prominence in production in several regions, due to increased demand in the consumer market. In the search to reduce productivity losses caused by pathogens, this work aimed to evaluate the cytogenotoxic potential of aqueous extracts of Syzygium aromaticum L., a possible alternative treatment for quinoa seeds. The seeds were treated with extracts produced from S. aromaticum flowers buds at 2, 4, 6 and 8%. A water control was included. Germination, first germination count, germination speed index, emergence and sanity were evaluated. The design was completely randomized, composed of 100 seeds in five treatments. The incidence of fungi was quantified and subsequently, the cytogenotoxicity test was performed on Allium cepa. It was observed that the treatment of quinoa seeds with aqueous extract of S. aromaticum only affected germination and vigor at the highest concentration used (8%) and reduced the incidence of fungi. A negative effect on cell division was demonstrated but no genotoxic effect. Used at 4% (m / v) it could be an alternative for the treatment of quinoa seeds.
