“…Ge, Li, et al. (2019) demonstrated that postharvest sodium nitroprusside treatment significantly enhanced PPO and POD activity in broccoli, mango, and blueberry. Nevertheless, other study showed the opposite results that higher activity of PPO and POD contributed to the chilling stress and lead to the formation of browning.…”

“…In our study, banana whole fruits were treated with the most common NO donor, SNP for analyzing the effects of NO. This treatment was effective as it generated NO and nitrite in peels (Figure S3) Though this treatment is also known to generate cyanide, SNP is a well-accepted NO donor used for studying effects of NO on postharvest shelf life, particularly owing to its efficiency in endogenous NO generation, cost-effectiveness and simple usage [40,41]. Moreover, it is known that the lateral effects of cyanide toxicity could be alleviated by the in-built detoxification system of higher plants which acts primarily through a key enzyme β-cyanoalanine synthase (β-CAS).…”

“…Barnes Fonte: Própria autoria A segunda via, tem a ver com a estimulação na atividade da peroxidase gerada pelo estresse causado pelos campos magnéticos, como acontece com outras enzimas que pertencem à categoria das antioxidantes como a catalase e a superóxido dismutase (ZHAO et al, 2018). Como reforço desta segunda via Ge et al (2019) argumentaram que o principal mecanismo de defesa dos fatores bióticos e abióticos no mirtilo é a produção de espécies reativas do oxigeno ERO (do inglês reactive oxygen species-ROS), que num nível adequado podem ajudar a manter a homeostase do fruto, no entanto, quando ocorre sobre produção, surge o efeito prejudicial que leva à senescência do produto. Em concordância com este argumento os campos magnéticos podem afetar a produção de ERO, dentro das quais está presente o peroxido de hidrogênio, substrato da peroxidase (considerada uma enzima antioxidante).…”

“…Ge et al (2019) reportaram 12 U/mg de atividade da peroxidase do mirtilo(considerando como unidade um incremento na absorbância de 0,01/min), o que resulta em 120 U/g. Esta atividade é maior que a encontrada nesta tese.…”
