Métodos de aplicação de diferentes concentrações de H2O2 em milho sob estresse salino

Abstract: Resumo: A aplicação exógena de H 2 O 2 tem demonstrado eficiência na aclimatação das plantas aos estresses bióticos e abióticos devido estimular a ativação do sistema de defesa antioxidativo. Neste sentido, objetivou-se com o trabalho avaliar a influência do método de aplicação de diferentes concentrações de H 2 O 2 sobre o crescimento inicial de plantas de milho irrigadas água salina. O experimento foi conduzido em ambiente protegido, com os tratamentos dispostos em delineamento inteiramente casualizado, em e… Show more

“…According to Gondim, Gomes Filho, Marques, and Prisco (2011), the application of H 2 O 2 has been proven as an efficient salinity stress mitigator, while Silva, Lacerda, Medeiros, Souza, and Pereira (2016) reported that H 2 O 2 is the viable way to acclimatize a plant exposed to an abiotic stress source because it makes the intracellular region activate the plant's defense responses to the stress caused by the excess of salts, resulting in cross-tolerance.…”

“…This result may be related to the lower absorption efficiency by the leaf (M1 and M3) due to cutin, present on the surface of the leaves, which determines the penetration capacity of the compounds, whereas the application via seed soaking was more efficient in absorbing the hydrogen peroxide. It is also noted that the foliar spraying of H 2 O 2 began at 80 days after sowing, which allows inferring that the H 2 O 2 may have had a late action compared to the method via seed soaking, with the previous exposure to H 2 O 2 possibly resulting in more effective acclimatization to the salt stress conditions (Silva et al, 2016).…”
