Phytochemical Enhancement in Broccoli Florets after Harvest by Controlled Doses of Ozone

This depository contains data obtained from several experiments in which broccoli florets were exposed to various concentrations of ozone by fumigation. The hypothesis is that under controlled (hormetic) doses of ozone, the secondary metabolism of plant tissue can be modified. Specifically, we focus on two metabolomics pathways: hydroxycinnamic acids and glucosinolates. However, it is also essential that these doses do not affect the quality of the products, and for this reason, physiological and quality parameters were also studied in the florets. The doses applied were essentially 5 uL/L for 60 and 720 min.本数据集收录了通过熏蒸法将西蓝花花序（broccoli florets）暴露于不同浓度臭氧的多组实验所得数据。本研究的核心假说为：在受控的（hormetic）臭氧剂量条件下，植物组织的次级代谢过程可被调控。具体而言，本研究重点关注两条代谢组学通路：羟基肉桂酸类（hydroxycinnamic acids）与硫代葡萄糖苷类（glucosinolates）。此外，为确保此类臭氧剂量不会影响产品品质，研究团队同时对西蓝花花序的生理与品质相关参数展开了测定。本次实验所采用的臭氧剂量主体为5 μL/L，处理时长分别为60分钟与720分钟。
