Hydrogen peroxide can enhance the synthesis of bioactive compounds in harvested broccoli florets

Hydrogen peroxide, at two concentrations, was used to induce phytochemical compounds in broccoli florets. This data set presents the effect of these doses compared to unexposed florets on quality, physiological aspects, redox status, secondary metabolism and gene expression for glucosinolate and polyphenol metabolic pathways.
The hypothesis of this work was to demonstrate that low doses of abiotic stresses, particularly hydrogen peroxide, are capable of maintaining the quality of horticultural products during storage, as well as inducing health-related phytochemical compounds.
The data set is divided into :
1) The determination of the hormetic (most appropriate) H2O2 dosage.
2) Quality parameters: color (hue angle), weight loss.
3) Redox state: ORAC, ascorbic acid, total phenols and total flavonoids.
4) Quantification of secondary metabolites: hydroxycinnamic acids (HCA) and glucosinolates (GLS).
5) Gene expression: chalcone synthase (CHS); phenylalanine N-hydroxylase (CYP79A2); tryptophan N-hydroxylase 2 (CYP79B3); dihomethionine N-hydroxylase (CYP79B3); dihomomethionine N-hydroxylase (CYP79B3).
N-hydroxylase (CYP79F1); flavanone 3-hydroxylase (F3H1); and phenylalanine ammonia-lyase (PAL).
